Raytracing not available in game. From Graphics menu, Presets you can choose the Raytracing preset, and then the Raytracing option is changed to Normal or High or Off. However you can't manually change it directly and there is no visual indication that Raytracing works.

As per https://gitlab.freedesktop.org/mesa/mesa/-/issues/8372 Raytracing with RADV works on the other Remake games, I tested at least Resident Evil remake 2 and 3.

Same issue on Nvidia hardware. RT is greyed out. You can choose a preset, but it doesn't actually enable RT.

Launch options:

GPU: Nvidia RTX 3060

Yeah, we don't know what libraries the game is using to determine DXR support, clearly not just D3D12 though (or it depends on some weird features we don't expose for some reason).

It's possible to enable RT in the game when using VKD3D-Proton on Windows with VKD3D_CONFIG=dxr11 and VKD3D_FEATURE_LEVEL=12_2.

So it comes down to some other library.

Which Nvidia driver version do you use on windows?

Latest Vulkan dev one.

This was recently confirmed to be a deliberate decision by the game; raytracing options are not available if it detects wine. Not much we can do here.

@doitsujin raytracing is available if you hide wine exports its somewhat working with amdvlk if you force SM/FL with vkd3d env vars, i was able to finish the demo with RT on. however an "assertion failed" error dialog does pop-up, which i can ignore and just keep playing.

Previous amdvlk would just crash after a while, i did open an issue on mesa issue tracker a while ago https://gitlab.freedesktop.org/mesa/mesa/-/issues/9559

For anyone watching this issue, figured out that if you put /WineDetectionEnabled:False onto the launch options for RE4 then you can enable/disable raytracing (just from the main menu!) and it works and there's an actual difference. On NV, anyway.
