Symptoms

Starting ca. August 11, 2026, Train Sim World 6 started crashing on Linux upon UEVR injection, if started in DX12 mode using -dx12 parameter. It could be linked with the TSW6 patch released on August 6 (https://steamdb.info/patchnotes/24589550/ ), although I encountered it a few days later.

After clicking "Inject", the UEVR overlay appears for a few seconds, but the game is not displayed in the headset in VR mode, and then crashes.

The game continues to work in DX11 mode, but graphics quality is very poor.

Reproduction

1. Launch Train Sim World 6 in DirectX 12 mode (-dx12 launch option)
2. Launch UEVR
3. Select openvr or openxr
4. Inject
5. The UEVR overlay is displayed, there is no video in the headset, then he game crashes and an UE crash window is opened.

No repository file or test is named. Start by reproducing the reported DX12 and UEVR injection sequence, then inspect the attached steam-3656800.zip Proton log and compare it with the working DX11 mode. Done would require identifying and addressing the cause of the crash or documenting the relevant compatibility finding.
