VRto3D

• OpenVR Driver that can render in SbS or TaB 3D with other formats converted to through ReShade
• Compatible games play great with a XInput controller. No motion controls required!
• VRto3D itself does not “fix” games for 3D, but it allows you to run VR modded (fixed) games on a 3D Display
• Supports User Profiles for individual games
• Provides HMD Pitch and Yaw emulation for games that require it
• Currently targeting OpenVR 2.5.1.
• Windows-only solution currently, but there are other solutions on Linux like Monado XR.
• Check out the video guide here (there are 2 parts):

Compatible 3D Displays

• 3D TVs & Projectors - work great, use Base Installation in SbS/TaB mode or potentially Frame Packing instructions
• Passive/Interlaced 3D displays - work great, use Interlaced instructions
• AR Glasses (Rokid, Xreal, Viture, RayNeo) - work great, use Base Installation instructions. If you don’t have a USBC port with DP-Alt mode on your PC, they require a compatible adapter - choose one with SBS and audio support. A USBC extension is also recommended
• Lume Pad - works great, use Base Installation instructions, requires Sunshine/Gamestream + Moonlight
• SR Displays (Acer Spatial Labs / Asus Spatial Vision / Samsung Odyssey 3D) - work great, use SR Displays instructions
• 3D Vision/Frame Sequential - works well, use Frame Sequential instructions
• Virtual Desktop with a VR headset - works with additional setup

Compatible VR Games & Mods

Checkout the Compatibility List to see if a game has been tested

Hotkeys

• Adjust Depth (Separation) with Ctrl + F3 and Ctrl + F4
  • Synchronize the convergence setting by also holding Shift - this often has issues in VR mods
• Adjust Convergence with Ctrl + F5 and Ctrl + F6 - this often has issues in VR mods
• Save all current settings (ones indicated with a "+" under Configuration) as a profile for the currently running game with Ctrl + F7 A beep will indicate success
• Reload the profile settings (ones with a "+") from the current game’s game.exe_config.json with Ctrl + F10 A beep will indicate success
• Reload the profile settings (ones with a "+") from default_config.json with Ctrl + Shift + F10 A beep will indicate success
• Toggle locking the SteamVR Headset Window to the foreground and focusing the game window with Ctrl + F8
  • This also works with WibbleWobbleReshade active
• Adjust HMD position and yaw origin with Ctrl + Home/End for Y, Ctrl + Delete/PageDown for X, Ctrl + Insert/PageUp for Yaw, and Ctrl + Shift + PageUp/PageDown for Height
  • Save hmd_height, hmd_x, hmd_y, hmd_yaw using Ctrl + F9
  • This is useful if you want to align the HMD to a lighthouse tracked position
• Check the Controls section and the Configuration table below to setup HMD camera controls for VR games (check the compatibility list to see if they are needed)
• Check the User Presets section for instructions on setting up your own Depth/Separation and Convergence presets and also reference the Configuration table below
• When Pitch/Yaw emulation is enabled, you can adjust the ctrl_sensitivity with Ctrl - and Ctrl + and the pitch_radius with Ctrl [ and Ctrl ]
• Toggle Auto Depth listener off/on with Ctrl + F11 (only works with VR mods that support it)
• Attempt to take a SbS Screenshot with Ctrl + F12 (doesn’t always work)

Configuration

• VRto3D has to be installed and SteamVR launched once for this config file to show up
• Modify the Documents\My Games\vrto3d\default_config.json for your setup
• Some changes made to this configuration require a restart of SteamVR to take effect
• Fields with a "+" next to them will be saved to a game’s profile when you press Ctrl + F7 and can be reloaded from either the game’s profile using Ctrl + F10 or the default_config.json using Ctrl + Shift + F10
• Reference Virtual-Key Code strings for user hotkeys

Base Installation

• A Single Display configuration is recommended, but you can also use a multi-display configuration if desired
• Install SteamVR
• Download the latest VRto3D release and copy the vrto3d folder to your Steam\steamapps\common\SteamVR\drivers folder
• Launch SteamVR once to generate the default_config.json and you should see a 1080p SbS Headset Window
• Close SteamVR
• Edit the Documents\My Games\vrto3d\default_config.json as needed - see what each setting does
  • Set your window resolution to match your fullscreen resolution (i.e. 3840x1080 for Full-SbS or 1920x1080 for Half-SbS)
  • Set your render resolution per eye to what you want - can save some performance by reducing this. If your display is half-SbS or half-TaB, then you can try setting this to that half-resolution
  • Configure any Virtual-Key Code settings to use keys that you want (especially user_load_keys settings as these load a defined depth+convergence preset)
• Download the latest VRto3D profiles for games and extract them to your Documents\My Games\vrto3d\ folder
• Run SteamVR to verify that you see the Headset window covering your entire display. This is usually not needed before running games.
  • The Headset window must be on your primary 3D display
  • Dismiss Headset Notice about Enable Direct Display Mode as this does nothing
• Try launching a VR game

  Single-Display Setup:

• Keyboard and Mouse are usable, but you may run into issues with accidentally clicking the wrong window or the cursor escaping the game window if the game’s mouse control is coded poorly
  • Can try using AutoCursorLock if the mouse keeps escaping
• Make the game run in windowed mode either in-game settings or with Alt + Enter This will alleviate controller input and fullscreen issues
• If needed, press Ctrl + F8 to lock the 3D window to the foreground and focus the game window
  • This is automated by default with the auto_focus setting when a VRto3D profile exists for the game
• If game controls & audio aren’t working, use Alt + Tab to switch to the game window
• To quit, exit the game and try to Alt + Tab out
  • If the 3D window remains in the foreground, press Ctrl + F8 to toggle the foregrounding off, and then Alt + Tab out

    Multi-Display Setup:

• Keyboard and Mouse are usable, but make sure the mouse is captured by the 2D game’s window
• Make sure you set your displays to EXTENDED MODE or this will not work
• Move all windows besides the Headset Window over to your second display
  • Some games provide the option to change which display to use - this is preferred over the options below
  • Can use mouse to drag over
  • Can use Windows shortcut keys to move windowed programs around Win + Left/Right
  • Can use Windows shortcut keys to move fullscreen programs and the SteamVR Headset Window around Shift + Win + Left/Right
  • May need to make the game windowed either in-game settings or with Alt + Enter

Interlaced, Checkerboard, and Anaglyph Installation (only if you need this output format)

• Complete the Base Installation section
• Optionally set tab_enable to true in Documents\My Games\vrto3d\default_config.json if you prefer to lose half vertical resolution instead of half horizontal resolution
  • If using interlaced mode, you want SbS for Column Interlaced and TaB for Row/Line Interlaced
• Download the latest ReShade with full add-on support
• Run the ReShade installer
  • Browse to to your Steam\steamapps\common\SteamVR\bin\win64 folder
  • Select vrserver.exe and click Next
  • Select DirectX 11 and click Next
  • Click Uncheck All and click Next, Next, Finish
• Download 3DToElse.fx and save it to Steam\steamapps\common\SteamVR\bin\win64\reshade-shaders\Shaders
• Run SteamVR
• Press Home to open ReShade and click Skip Tutorial
• Select To_Else in the menu to enable 3DToElse
• Disable ReShade’s Performance Mode checkbox
• Change 3DToElse settings:
  • Set Stereoscopic Mode Input to Side by Side (or Top and Bottom if you set tab_enable above)
  • Set 3D Display Mode to the type needed for your display (even anaglyph)
  • Eye Swap can be toggled if needed
  • Don’t touch Perspective Slider
• Enable ReShade’s Performance Mode checkbox
• Once configuration is complete, you can run everything the same way as the Base Installation
• If settings don’t save, you may have to manually edit Steam\steamapps\common\SteamVR\bin\win64\ReShade.ini and disable Tutorial with TutorialProgress=4

FramePacking, HDMI 3D (only if you need this output format)

• Complete the Base Installation section
• In Documents\My Games\vrto3d\default_config.json set these settings:
  • window_width to 1920 or 1280 depending on your desktop resolution
  • window_height to 2205 or 1470 depending on your desktop resolution
  • tab_enable to true
  • framepack_offset to 45 for 1920x2205 or 30 for 1280x1470 (this may vary by display)
• More instructions and discussion are in this forum
• Create one of these Custom Resolutions in Nvidia Control Panel or CRU:
• frame_packed_720p : resolution 1280x1470, 60Hz
  • horizontal: 1280 active; 110 front, 40 sync, 220 back (1650 total)
  • vertical: 1470 active; 5 front, 5 sync, 20 back (1500 total)
• frame_packed_1080p : resolution 1920x2205, 24Hz/60Hz
  • horizontal: 1920 active; 638 front, 44 sync, 148 back (2750 total)
  • vertical: 2205 active; 4 front, 5 sync, 36 back (2250 total)
• May need to use CVT reduced blank specs for success with 1080 60Hz, but 60Hz is not standard and may not work at all
  • horizontal: 1920 active; 48 front, 32 sync, 80 back (2080 total)
  • vertical: 2205 active; 4 front, 5 sync, 36 back (2250 total)
• It may be necessary to remove other resolutions with CRU to avoid games changing the resolution. Hopefully running them in windowed mode (required for VRto3D) will prevent issues though

SR (Simulated Reality) Displays (only if you need this output format)

• If you don’t need VRto3D features (User Hotkeys, Per-Game Profiles, Pitch/Yaw Emulation, etc) and XRGameBridge is more stable, that may be preferable to use instead of VRto3D for games/mods with OpenXR support
• SR displays work in either Multi or Single Display environments
  • For both, read the Base Installation configuration and usage instructions to ensure that you get a proper 3D image and can control the game
• Complete the Base Installation section
• Install the software package provided with your SR display, if yours did not come with one, install the SR-VERSION-win64.exe and simulatedreality-VERSION-win64-Release.exe from the LeiaInc Github
• Download the latest ReShade with full add-on support
• Run the ReShade installer
  • Browse to to your Steam\steamapps\common\SteamVR\bin\win64 folder
  • Select vrserver.exe and click Next
  • Select DirectX 11 and click Next
  • Click Uncheck All and click Next
  • Select 3DGameBridge by Janthony & DinnerBram and click Next
  • Click Finish
• Run SteamVR
• Press Home to open ReShade and click Skip Tutorial
• Click on the Add-Ons tab
• Select srReshade in the menu to enable it
  • Expand the srReshade dropdown and if you get a Status: Inactive - Unable to load all SR DLLs then you need to install the SR Runtime + SDK from Leia’s Github above
  • 3D can be toggled on and off by using srReshade’s Ctrl + 2 hotkey
• Click on the Home tab
  • Enable ReShade’s Performance Mode checkbox
• Once configuration is complete, you can run everything the same way as the Base Installation
• If settings don’t save, you may have to manually edit Steam\steamapps\common\SteamVR\bin\win64\ReShade.ini and disable Tutorial with TutorialProgress=4
• If you experience a super dark screen, try enabling a random ReShade shader

Frame Sequential (WibbleWobble) Installation (only if you need this output format)

• Using WibbleWobble is at your own risk to your monitor/emitter/glasses. It works well but is unofficial
• WibbleWobble works with 3DVision, Open3DOLED, and several DIY hardware solutions
• WibbleWobble Hotkeys may not work on non-english keyboard layouts
• If you don’t need VRto3D features (User Hotkeys, Per-Game Profiles, Pitch/Yaw Emulation, etc) it will be easier to use the WibbleWobbleVR plugin directly

  Initial Install

• 3DVision installation detailed below. Other configurations can still follow the WibbleWobble Reshade Add-On instructions but will need to check the WibbleWobble GitHub for other WibbleWobble Settings
• Complete the Base Installation section and modify these VRto3D settings in Documents\My Games\vrto3d\default_config.json:
  • Set the Render Resolution to match your Fullscreen Resolution or something lower for performance
  • Set the window_width to 2x your render_width (i.e. 3840x1080 for 1920x1080 per-eye)
    • This sometimes causes SteamVR to crash. If you want more stability and are ok with half-width, you can set window_width and window_height to your desktop resolution
  • Leave it in the default SBS display mode
  • May need to test and see if async_enable provides better performance
  • If you decide to target 100Hz refresh rate (recommended for performance/stability), set display_frequency to 50.0
    • If using async_enable, you may want to set this value to x1.5 your target refresh rate (i.e. 75.0 for 50.0)
• Use 3D Fix Manager to install the 3D Vision Driver
  • If the emitter driver didn’t install, browse to the place you installed the manager and run the Drivers\3DVisionControllerDriver\3dvisioncontrollerdriver.exe
• Download the latest WibbleWobble Release and extract it somewhere without spaces in the path like C:\
• Under the WibbleWobbleClient folder, run Register.bat as an administrator and reply Yes if prompted
• Under the WWReshadeAddon\Reshade folder, run the included ReShade Setup
  • Browse to to your Steam\steamapps\common\SteamVR\bin\win64 folder
  • Select vrserver.exe and click Next
  • Select DirectX 11 and click Next
  • Click Uncheck All and click Next, Next, Finish
• Under the WWReshadeAddon\Release\x64 folder, copy all files to your Steam\steamapps\common\SteamVR\bin\win64 folder
• Check if there is a WibbleWobble.zip folder you can download from here and extract to %APPDATA%\..\LocalLow\PHARTGAMES\
  • If one is available for your monitor, you can skip CRU, NVTimingsEd, and WibbleWobble Config steps below
• Download the latest CRU Release and save it to your WibbleWobble folder
• Run CRU.exe and grant it admin
  • Take note of your monitor’s EDID (first 7 characters in the dropdown list)
  • Exit CRU
• Download the latest NvTimingsEd Release and save it to your WibbleWobble folder
• Run NvTimingsEd.exe and grant it admin
  • From the drop down list, select your monitor’s EDID you got from CRU (AUS_27B1 for Asus PG278QR for example)
  • Choose your target refresh rate / framerate you want to run 3D at
  • Click Edit but don’t change anything
  • Copy the nearest integer refresh rate for WibbleWobble’s Sync Rate HZ
  • Copy the X value for WibbleWobble’s Open Delay Microseconds

• Start SteamVR
• Press Shift + END to start WibbleWobble
• Press Shift + / or Ctrl + F8 to unfocus WibbleWobble
• Launch VR Game/Mod
• If using VRto3D auto_focus the WibbleWobble window should be brought to the foreground and the game window focused
  • If needed, press Ctrl + F8 to foreground WibbleWobble and focus the game window
• If needed, use Shift + , to flip eye output
• If controls or audio aren’t working, Alt + Tab to the game window
• Mouse controls can work on a single display as long as you are clicking somewhere on the game window that is covered by WibbleWobble

  Troubleshooting

• If SteamVR crashes, close everything, you may need to temporarily edit your VRto3D window_width to half, run SteamVR and activate WibbleWobble, close everything, then revert to full
• If you get a black screen, open WibbleWobble config with Shift + END and under Game Config set Window Size X to either half or double your current setting, and then immedietely set it back to the original value. If SteamVR crashes, close everything and try again.
• If you experience ghosting, try turning on your monitor’s Lightboost or Ultra Low Motion Blur or ULMB feature. You may have to enable 3DVision in Nvidia Control Panel for this setting to be available
• If your 3D Emitter doesn’t activate, try the following:
  • Unplug/replug the emitter
  • Toggle 3DVision On/Off
  • Restart SteamVR
• If you are getting too much wobbling, try the following:
  • Toggle VSync off or on in-game
  • Close all other applications
  • Toggling GSync On/Off
  • Toggling 3DVision On/Off
  • Or try rebooting
• If WibbleWobble settings are really messed up, delete your %APPDATA%\..\LocalLow\PHARTGAMES\WibbleWobble folder

Notes

• The primary display will be where the “Headset” window is located and should be 3D capable
• The game’s main window has to be in focus for control input from your mouse/keyboard/controller to work
• SteamVR may still complain about Direct Display mode, but this can be safely dismissed
• Exiting SteamVR may “restart” Steam - this is normal
• Overlays generally won’t work on this virtual HMD
• XInput controller is recommended
• SteamVR doesn’t support HDR currently
  • AutoHDR may work, but some games will be too dark or too bright
• DLSS, TAA, and other temporal based settings can create a halo around objects. Most VR mods have fixes for this, but some may not

Controls

• If you want to use Steam Input
  • Open Steam->Settings->Controller
  • Toggle on Enable Steam Input for Xbox Controllers
  • Click Edit on the Desktop Layout and then select Disable Steam Input
  • On SteamVR’s library page, click the Controller Icon and select Disable Steam Input
  • Generally you need to start SteamVR first and separately from the game for Steam Input to work
• This project is primarily targeted for VR mods of flatscreen games, not full VR games. As such, there is only HMD pitch & yaw emulation and no VR controller emulation
• You can setup a Lighthouse + Vive Tracker + tracked controllers with VRto3D for a seated play area. See this guide for details
• Several VR controller only games can be made to work by using Driver4VR, a paid SteamVR Vive controller emulator. Games with mainly pointer controls work ok. Games with a lot of interaction/movement don’t work well.
• Optional HMD pitch_enable and yaw_enable emulation can be turned on to help with games or mods that need it (maps to XInput right stick)
  • Reference Virtual-Key Code to find the strings to use for these hotkeys
  • The ctrl_toggle_key can be set and used to toggle these settings on/off in-game (only functions if pitch_enable and/or yaw_enable is set to true)
  • The ctrl_toggle_type can be set to either "toggle" pitch/yaw on/off or "hold" that disables them while the button is held
  • The pose_reset_key can be set to allow resetting the view to the original position and orientation
  • Both of these keys can be set to XInput buttons & combinations or single keyboard/mouse keys as outlined in User Presets - Load Keys below
  • The pitch_radius can be set to make the pitch emulation move along a semicircle instead of just tilting up/down in place. Use the Hotkeys to adjust this in-game
• OpenTrack 3DoF support is available over UDP loopback at the configured open_track_port when use_open_track is true. It can be used in combination with Pitch/Yaw emulation

User Presets

• If you swap between different convergence settings in-game, sometimes you will end up with black bars on the sides of the screen or you may not see a change immediately. If you reload/restart/reinitialize the VR mod, you should see the change
• It is recommended to use a single convergence setting for all your presets given the above issue with some VR mods
• Create any number of user depth/separation & convergence hotkeys in the user_settings area of the default_config.json
  • A user preset looks like this:

  •   {
          "user_load_key": "VK_NUMPAD1",
          "user_store_key": "VK_NUMPAD4",
          "user_key_type": "switch",
          "user_depth": 0.4,
          "user_convergence": 4.0
      },
    

• A Load key and a Store key can be configured to load and save Depth/Separation and Convergence settings for a preset
  • Load keys can use XInput buttons & combinations as well as single keyboard/mouse keys
    • The Guide button can be used, but not in combinations
    • XInput Combinations can be set like this "XINPUT_GAMEPAD_A+XINPUT_GAMEPAD_B"
  • Store keys can only use single keyboard/mouse keys
  • Reference Virtual-Key Code to find the strings to use for these hotkeys
• The Load key can be configured to "switch" to the user depth/separation & convergence setting, "toggle" between the preset and the previous setting every 1.5s, or "hold" the user setting until the key is released
• The Store key will update your user Depth/Separation and Convergence setting to the current value (this only saves while the game is running - you need to create a game profile as detailed below to store it permanently)
• It is recommended to have a single user preset of "switch" type that matches the default depth/separation & convergence so you can easily get back to the default

Profile Creation Steps:

1. Modify or copy and create user preset(s) in default_config.json (or preferably in the Game.exe_config.json if one already exists) for the game you want to play
2. If applicable, modify hmd_height, fov, pitch_enable, yaw_enable, pose_reset_key, ctrl_toggle_key, ctrl_toggle_type, pitch_radius, ctrl_deadzone, ctrl_sensitivity for the game profile
3. If the game is already running, use Ctrl + Shift + F10 to reload the default_config.json (or Ctrl + F10 to reload the Game.exe_config.json) with your new settings and presets
4. Adjust depth/separation (Ctrl + F3 and Ctrl + F4 with + shift if possible) & convergence (Ctrl + F5 and Ctrl + F6) for a preset
5. Use the configured user_store_key to temporarily save the current depth/separation & convergence values to the preset
6. Repeat 4 & 5 for each preset you need
7. Adjust depth/separation & convergence back to what you want the default to be (if you have a default "switch" preset, you can use its configured user_load_key)
8. If applicable, adjust the ctrl_sensitivity with Ctrl - and Ctrl + and the pitch_radius with Ctrl [ and Ctrl ]
9. Save the profile with Ctrl + F7
10. Open your new profile from Documents\My Games\vrto3d in a text editor and make final adjustments like: making all the convergence values match to avoid rendering or performance issues, changing virtual-key mappings, or tweaking other values/settings
11. Close out of SteamVR and the game and restart the game. You should hear a loud beep to indicate the profile loaded. Test the profile and you can still make any adjustments per above instructions
12. Share your Documents\My Games\vrto3d\Game.exe_config.json with others

Troubleshooting

• If you set the Window Resolution to anything above your desktop resolution, SteamVR won’t start
• If SteamVR crashes and disables add-ons, you will need to re-enable VRto3D in the SteamVR Status window
• The first thing to try is deleting your Steam\config\steamvr.vrsettings and Documents\My Games\vrto3d\default_config.json
• If you have used other SteamVR drivers that also create a virtual HMD, you will need to disable and/or uninstall them
  • Run SteamVR
  • On the SteamVR Status window, go to Menu -> Settings
  • Change to the Startup / Shutdown tab
  • Click Manage Add-Ons
  • Turn Off any virtual HMD drivers (ALVR, VRidge, OpenTrack, VCR, iVRy, etc)
  • if issues still arise, try a Clean SteamVR Install and delete your Steam\steamapps\common\SteamVR folder
• If you have a VR headset and run into issues with this driver, here’s some things to try:
  • Disconnect VR headset from computer
  • Clean SteamVR Install
  • Set SteamVR as OpenXR Runtime

Building

• Clone the code and initialize submodules
• Define STEAM_PATH environment variable with the path to your main Steam folder
• Open Solution in Visual Studio 2022
• Use the solution to build this driver
• Build output is automatically copied to your SteamVR\drivers folder
