No raytracing on Linux?

[Tevur]

I have an AMD GPU and at least on Benchmark, the option to set raytracing is off and grayed out.

On Windows you can activate it.

Is this a bug? Will it get fixed? Do I need any commands to enable it?

raytracing worked on linux for years. works for me on my 7900xt to. guess there is something with your config.

you need mesa and amdvlk for it.

[Tevur]

Hmm, amdvlk is the worse AMD version. The Mesa Vulkan driver is vulkan-radeon and far better for gaming performance wise.

So the question is why is, why is raytracing blocked with vulkan-radeon

Edit: I installed and tried amdvlk... it crashes the whole desktop environment on startup. not worth the meddling

[MCNacho-ナチョ]

mhh...


VKD3D_CONFIG=dxr %command%

add this to steamlaunch options maybe it works

No, unfortunately not working

I can't find Ray tracing option on Windows either, I like to disable that thing but I can't find it.

Oh, this explains it. I'm on OpenMandriva Linux and also can't choose RT. I thought it was an AMD thing.

Launch the game with the

/WineDetectionEnabled:False

parameter

amdvlk is AMD's official driver. radeon-vulkan is the open source driver
take a guess how many people with AMD gpus actually care about the ray tracing

also, ray tracing in this game only replaces SSR, it's not worth using

[DDENN]

its only for water reflection anyway, dont affect much

RT is fine with the open source driver, although often not with as high fps as on windows. Depends on the game.
MH Wilds (Benchmark) is the first game I have, which disables RT.

And no one uses the AMD Drivers for gaming on Linux. They are crap, if you want competing GPU performance.

Windows Ray tracing isnt showing up for windows either i dont think maybe its just the beta

OP is talking about the benchmark. Ray Tracing is definitely an option for AMD cards in the benchmark. The SSR is...uh...not good, but neither are the ray traced reflections. I don't think anyone is missing much either way.

That is good, but doesn't work.
Though I have found the issue on vkd3d-proton's Github...
https://github.com/HansKristian-Work/vkd3d-proton/issues/2331
Seems as they know of the problem, that's why they set up a wine detection to deactivate RT...
So, hope they work on it till release.

As to why I want it:
I occasionally do benchmarks with raytracing to do camparative statistics for windows, other kernels or mesa updates and would like to use this benchmark (and later the full game) for that.

[BEEP!]

I wouldn't even bother with the RT it's looks like it's just reflections and the RE engine has never done good RT reflections. it looks better with it off.

This one worked perfectly for me: thank you !
