RDRVR 0.4.0: native-stereo VR for the PC port of Red Dead Redemption.

Requires RedHook v0.8 (not included). Install it first and set [DirectXHook] Disabled=true in its RedHook.ini.

What's new

• Render resolution (General tab, "Render resolution"; off by default; from the next start). The game now renders at your headset's height, whatever your monitor's resolution, without NVIDIA DSR or any driver setting. Until now the game's resolution list only held your monitor's modes. You can choose:

  • Automatic: the height your headset's runtime asked for in its last session (with Virtual Desktop, its quality preset), never below your own resolution; the first start with a runtime uses the game's own size;
  • a height named for the headsets (and Virtual Desktop quality levels) it fits, 1600 to 3264 tall, for example "2208 tall: Quest 3 (3926 x 2208)", "1600 tall: Valve Index", "2560 tall: Bigscreen Beyond", "2688 tall: Virtual Desktop High".

  In Windowed mode your window keeps its size, and the larger frame is scaled into it. The game's own Graphics menu shows the size, and graphicsOptions.xml keeps your own resolution, so the game starts as before with the option off or without the mod. With "Eyes in the headset's shape" on, each eye is now drawn up to this height (before, at most your game resolution's height), so the two together give the headset its full sharpness for fewer pixels. Larger costs more GPU time; a size too large for your graphics card's memory is greyed out.

• Safer resolution changes in VR. Changing the resolution in the game's Graphics menu while in the headset used to leave the mod copying images of the old size. Now the mod switches to the flat game on the cinema screen, and its menu asks you to restart the game.

• The HUD panel and the cinema screen are now filtered down to at most 2560 pixels wide, so a large frame doesn't shimmer on them. At 2560x1440 they're unchanged. This also applies with a 4K monitor or DSR: [XR] UiQuadMaxWidth=0 and CinemaMaxWidth=0 in RDRVR.ini bring back 0.3.0's full-size images.

This release was checked in a simulator (Windowed mode); it has not been tried in a headset yet. 0.3.0's changes are in it too (other game builds, the menu, the options off by default).

Install

1. Install RedHook into the game folder (see above).
2. Download RDRVR-0.4.0.zip below, unzip it, and run Install.cmd. It finds the game through Steam, or asks for the folder. It replaces an earlier RDRVR install, and your settings in %LOCALAPPDATA%\RDRVR are kept.
3. Start your headset's OpenXR runtime, then the game.

To uninstall, run RDRVR_Uninstall.cmd in the game folder.

Known issues

• "Render resolution" has been tried in Windowed mode only (the game's Screen Type): use Windowed with it for now. In Fullscreen the game may undo a size smaller than your monitor's at the start.
• Vaulting over a fence or a low wall has not been checked yet.
• DLSS (in the anti-aliasing choice) is experimental and feels laggy in the headset; FXAA is the default.
• Rarely, the game freezes or slows to a few frames a second (seen a few times in testing; the cause is not known yet). If it happens, please attach RDRVR.log to an issue.
• Only a Quest 3 (Touch controllers) has been tested on real hardware.
