1. Download the KHARVOX: ARGENT release ZIP.
2. Extract the complete archive into a new, writable folder of your choice. Do not run the launcher from inside the ZIP file, and do not copy ARGENT into the DOOM Eternal installation folder.
3. Make sure DOOM Eternal, your headset software and your OpenXR runtime are installed and ready. Steam and Microsoft Store installations are supported.
4. Run ArgentLauncher.exe from the extracted ARGENT folder.
5. Select DOOMEternalx64vk.exe, configure your VR options and press PLAY.

Keep all extracted ARGENT files together in the same folder. Start DOOM Eternal through ArgentLauncher.exe whenever you want to play in VR.

Connect your headset and controllers and start your OpenXR runtime. Select the DOOM Eternal executable, then press PLAY. Steam and Microsoft Store installations are supported.

Keep the game window focused for input. The native VR intro runs before the game. After its first start, Disable VR Intro appears under Rendering.

KHARVOX: ARGENT is a private project developed with limited resources. Compatibility and performance can vary between hardware configurations.

AMD graphics cards currently have known rendering issues. Compatibility may improve with future updates. Some effects, particularly water, can also produce visual artifacts in VR.

The mod has been tested with VDXR, SteamVR�s OpenXR runtime and Meta�s OpenXR runtime. Other runtimes have not been validated and are unsupported.

Quest: VDXR or MetaXR

Index: SteamVR

Please do not use SteamVR with Meta headsets. It�s known to cause issues!

70% Renderscale, FSR on, DLSS off, HighDetails

The game world is rendered in stereoscopic VR. Supported menus and tutorials automatically appear on a virtual screen.

Enable 3D Cinematics for stereoscopic presentation of supported cinematic sequences. Restart the game after changing rendering options.

100% is the native reference pixel count. Lower values reduce rendering work.

Enable FSR Upscaling to upscale reduced eye images and sharpen the result. FSR is disabled at 100% or higher. Start at 100%, then reduce gradually if needed.

The SteamVR path uses 100% and does not apply the launcher�s FSR resolution reduction. Adjust resolution through SteamVR instead.

Select DLSS in the game�s graphics settings if your graphics card supports it. Stereo DLSS uses separate histories for each eye but remains experimental.

DOOM Eternal normally applies temporal anti-aliasing, which can make the image look blurry in VR. ARGENT blocks native TAA in stereo rendering.

Disable FSR Upscaling in the launcher when using DLSS. FSR forces the game�s anti-aliasing off, so choose either FSR or DLSS. Compare image clarity, stability and performance in your headset.

Enable Desktop Mirror (Right Eye) under Rendering to display the right-eye view on your monitor. This is useful for spectators, screenshots and recording. It is disabled by default.

The mirror preserves the eye image�s aspect ratio. Black bars may appear because a VR eye image does not usually match a 16:9 desktop window.

Choose the desktop output resolution from the dropdown:

• 720p: 1280 � 720
• 1080p: 1920 � 1080
• 2K / 1440p: 2560 � 1440
• 4K: 3840 � 2160

The default selection is 1080p. When Desktop Mirror is disabled, the desktop window uses 720p.

Mirror resolution controls the desktop output size, not the headset�s rendering resolution. Higher output resolutions may increase GPU overhead and will not add detail beyond the rendered eye image. Restart the game after changing these settings.

Index controller can access the Pause Menu with Touchpad click.

See Controller Binding for the full mapping.

Under Movement, choose smooth or snap turning, adjust turning speed or snap angle, and select head-directed or off-hand-directed movement.

Enable Left Handed Mode to reveal the layout selector:

• Button Swap: Moves weapon trigger/grip and Use/melee stick-click to the left controller. Equipment trigger/grip and Mission Info/Dossier stick-click move to the right. Face buttons and stick directions stay on their original sides.
• Button and Stick Swap: Also swaps the face-button pairs and stick directions. Move and select weapons with the right stick; turn, select Crucible and open the weapon wheel with the left stick.

The physical Menu button remains Pause.

Enable Virtual Gunstock for two-hand support. Hold the off-hand grip near the weapon�s support point to grab it. Release the grip to let go. A grip press away from the weapon cycles equipment.

Physical Glory Kill / melee uses controller speed, the Punch speed threshold and the selected punch hand. A valid target and the game�s normal activation conditions are still required.

PSVR2 Adaptive Triggers is experimental and requires PlayStation VR2 hardware, a working PSVR2 SteamVR setup and PSVR2 Toolkit installed separately. PSVR2Toolkit version 1.0 or higher is required.

It provides weapon-specific adaptive-trigger resistance on the weapon hand. Normal controller rumble works independently.

Missing or inactive Toolkit software does not block game startup, but adaptive-trigger effects will be unavailable.

Use compatible bHaptics gear and bHaptics Player for Windows. Pair and test your devices in the Player before starting the game, then enable bHaptics under VR Options.

Missing hardware, an unavailable Player or a local bridge error does not block game startup, but suit feedback will be unavailable. Normal controller rumble works independently.

Extended Logging is disabled by default. Enable it under Rendering before pressing PLAY when investigating a problem.

Additional logging can affect performance. Disable it again when you have finished collecting logs.

This repository contains the ARGENT source code. The instructions below describe the Windows build and its required dependencies.

• Windows x64.
• Visual Studio with the Desktop development with C++ workload, MSVC x64 tools, MASM and a Windows SDK. The current release build uses Visual Studio 2026.
• CMake with support for your installed Visual Studio generator, Git and PowerShell.
• The complete project assets and dependencies under third-party, including the OpenXR loader, Vulkan headers, MinHook, SPIRV-Cross, cgltf, pocketmod, bHaptics and PSVR2 Toolkit runtime components.
• An x64 Release installation of glslang and SPIRV-Tools compatible with the MSVC toolchain. Its install directory must contain include/glslang/Include/glslang_c_interface.h, bin/glslang.exe and these libraries under lib: glslang.lib, glslang-default-resource-limits.lib, SPIRV-Tools-opt.lib and SPIRV-Tools.lib.

The bHaptics runtime DLL is not included in this repository. Obtain bhaptics_library.dll from the bHaptics SDK and place it in third-party/bhaptics/ before building the runtime package.

Clone the repository and initialize its submodules:

git clone --recurse-submodules https://github.com/CactusVRStudios/KHARVOX-ARGENT.git
cd KHARVOX-ARGENT
git submodule update --init --recursive

Run the following from the project directory in a Visual Studio Developer PowerShell. Replace the example glslang path with your own installation path. If using a different Visual Studio version, select its matching CMake generator.

cmake -S . -B build-clean -G "Visual Studio 18 2026" -A x64 `
  -DARGENT_CLEAN_RELEASE=ON `
  -DARGENT_BUILD_SFS_TOOLS=ON `
  -DARGENT_GLSLANG_ROOT="C:/Dependencies/glslang"

cmake --build build-clean --config Release --target `
  ArgentLayer ArgentLauncher ArgentRuntimeProbe `
  KharvoxBhapticsBridge KharvoxPsvr2Bridge --parallel

The binaries are written to build-clean/Release. Keep the required runtime DLLs, shader binaries and assets with the launcher; the EXE alone is not a complete installation.

After building, use the release packaging script. Choose an unused release number and set -CrtDirectory to the x64 Microsoft Visual C++ redistributable directory installed with your Visual Studio toolchain:

.\tools\package_release.ps1 -ReleaseName ARGENT-Alpha-Test-r999 `
  -CrtDirectory "C:/Path/To/VC/Redist/MSVC/<version>/x64/Microsoft.VC145.CRT"

The script creates a runtime folder and ZIP under releases, verifies the bundled integrations and preserves calibration defaults. It refuses to overwrite an existing release. Playable packages contain runtime files and assets only; source documentation, logs and debug symbols stay outside the package.

To build and run the test suite:

cmake --build build-clean --config Release --parallel
ctest --test-dir build-clean -C Release --output-on-failure

Some tests require a Vulkan-capable GPU, an OpenXR runtime or developer capture fixtures that may not be included in the source distribution. Automated tests do not replace gameplay and headset testing.
