Star Ocean The Divine Force VR

A native VR mod for Star Ocean The Divine Force (Steam, PC). You play in third person with a gamepad as
usual; the game is rendered in true per-eye stereo on your SteamVR headset through OpenXR.

Features

• Native stereo: each eye is rendered separately, with real depth. This is not alternate-eye rendering (AER).
• Head tracking: look and lean around the game world.
• Rendered at your headset's resolution: the mod uses the headset's recommended per-eye resolution, with a render scale.
• HUD on its own panel: the HUD floats in front of you. You can set its distance, size, height, and whether it stays fixed in the world or follows your head.
• In-headset settings menu: open it with Insert, or hold L3 + R3 on the gamepad. Changes apply live and are saved to config.txt.
• Foveated rendering (NVIDIA RTX): the outer area of each eye is shaded at a lower rate for more fps. Fixed mode keeps the sharp area at the centre of each lens. Eye-tracked mode moves it with your gaze on headsets with eye tracking (OpenXR XR_EXT_eye_gaze_interaction).
• TAA control: turn the game's TAA off, reduce its camera jitter, or add sharpening to counter TAA softness.
• Smooth output: frames are sent to the headset at its full refresh rate, independent of the game's frame rate. The mod corrects each frame for your latest head rotation.

Requirements

• Windows 10/11 and the Steam version of the game. The mod checks the game build and does nothing on an unknown one.
• A SteamVR headset, with SteamVR set as the OpenXR runtime.
• A gamepad.
• A strong PC. Native stereo renders the scene twice per frame, so expect a high CPU and GPU load. Foveated rendering needs an NVIDIA RTX GPU.

Install

1. Download the zip from Releases.
2. Copy xinput9_1_0.dll and openxr_loader.dll into the game folder, next to SO6.exe. For example: ...\steamapps\common\STAR OCEAN THE DIVINE FORCE\.
3. Start SteamVR, then start the game from Steam.

On first start the mod creates config.txt and so6vr.log in the game folder.

Uninstall: delete xinput9_1_0.dll and openxr_loader.dll from the game folder. You can also delete config.txt and so6vr.log.

Controls

Key	Action
Insert, or hold L3 + R3	Open or close the settings menu
F8	Switch between the flat virtual screen and stereo
F9	Recentre the view (also moves the HUD panel)
F10	Show or hide the HUD panel

The title screen is always shown on a flat virtual screen; stereo starts in game.

Settings

Everything is in config.txt in the game folder. Each setting is documented there, and most can also be
changed in the settings menu. The most useful ones:

Setting	Values	Notes
RenderMode	Flat, Native	Flat = virtual screen; Native = full stereo
RenderResolution	Auto, Game, WxH	Auto = the headset's recommended per-eye size
RenderScale	0.5–2.0	Lower for more fps, higher for sharpness
Foveation	Off, Fixed, Gaze	NVIDIA RTX only. Gaze needs eye tracking (falls back to Fixed)
FoveationStrength	Low, Medium, High	Start with Medium
TAA	true, false	false = sharpest image, but edges shimmer
TaaJitter	0.0–1.0	Lower = less TAA blur, more aliasing
Sharpen	0.0–1.0	Sharpening of the headset image
HudDistance, HudWidth, HudOffsetY, HudAnchor	metres; World / Head	HUD panel placement
ReticleInScene, ReticleDistance	1/0; metres	Draws the D.U.M.A. aim crosshair in the 3D view (default 10 m) instead of on the HUD panel
MenuDistance, MenuWidth, MenuOffsetY, MenuAnchor	metres; World / Head	Settings menu placement
WorldScale	1.0 = real scale	Larger values exaggerate head movement and depth

Troubleshooting

• Nothing in the headset: check that SteamVR is running and is the active OpenXR runtime. Then look in so6vr.log.
• Low frame rate: lower RenderScale (for example 0.8), or turn on Foveation = Fixed.
• Image too soft: try TaaJitter = 0.5, Sharpen = 0.3, or TAA = false.
• Reporting a problem: please attach so6vr.log, and for crashes the game's SO6.crash.* files.

Troubleshooting

• Image too soft: try TaaJitter = 0.5, Sharpen = 0.3, or TAA = false.
• Reporting a problem: please attach so6vr.log, and for crashes the game's SO6.crash.* files.

How it works (short version)

• Loading: the mod is an xinput9_1_0.dll proxy that the game loads at startup.
• Stereo: the game renders the left eye with a head-tracked camera. The mod then replays that frame's render commands for the right eye, with the camera matrices swapped at constant-upload time. Temporal effects, TAA's linear-depth state and the game's frame-history textures are kept separate per eye.
• HUD: UI draws are redirected to their own texture. A black/white matte recovers correct transparency.
• Headset output: a separate thread with its own D3D11 device runs the OpenXR frame loop at the headset's refresh rate.

Technical notes are in docs/.

Building

The DLL is cross-compiled on Linux with clang-cl and lld-link.

What you need:

• LLVM 22 (the MSVC STL needs Clang ≥ 22).
• The MSVC STL/CRT and Windows SDK headers and libraries. Copy them from your own Visual Studio installation; they are not included here.
• MinHook.
• The OpenXR SDK headers and the prebuilt Windows loader.

Steps:

1. Run scripts/setup_env.sh /path/to/toolchain.zip. It sets everything up (paths in scripts/env.sh).
2. Run scripts/build.sh. The output is build/xinput9_1_0.dll and build/openxr_loader.dll.

• Dear ImGui (Omar Cornut), MinHook (Tsuda Kageyu), the Khronos OpenXR SDK and loader, and the RenderDoc in-application API header.
