No ray-tracing capable GPU found with RX 6600 Arch Linux Wayland

[raining]

From what I've read, it should be possible to run this game on linux with RX 6600 and vulkan drivers, but I get this message anyway. I am updated to the latest GPU drivers and have tried both AMDVLK and MESA RADV. It seems like it just doesn't recognize this GPU as a raytracing capable one for some reason. Heres the output of Steam System Information for my video card:

Q2RTX searches for Vulkan's raytracing extensions. You can check if you have them by running

vulkaninfo|grep VK_KHR_ray

If it's present you'll see something like

        VK_KHR_ray_query                            : extension revision 1
        VK_KHR_ray_tracing_pipeline                 : extension revision 1

If output is empty then your driver does not have required extensions.

Last I heard several months ago - only proprietary driver AMDGPU-PRO supported raytracing on Linux.

Thanks for letting me know the name of the ray tracing extensions! I guess those articles I read must have been talking about dev drivers or something, cuz yeah I didn't get those in my vulkaninfo output.

[Raph]

I believe the AMDGPU PRO driver supports it, but has worse performance for games overall

Runs great on my RX 6800 not sure why its not running for you op.

Running that command shows me

WARNING: lavapipe is not a conformant vulkan implementation, testing use only.
WARNING: lavapipe is not a conformant vulkan implementation, testing use only.

instead of blanc output. I take it I should just wait for a future driver update? I didn't buy this GPU with raytracing in mind, but I am a bit curious to see it, just not enough to try installing AMDGPU PRO.

[Ravo]

It's quite convenient that I ran into this thread. I was looking for a reason why my new AMD GPU wasn't launching, and ray tracing not being implemented into AMD's open source drivers is a good enough excuse for me. Still, the 6000 series of cards have been out for a couple of years now. I wish there was more to work with than the latest beta drivers.

Ray tracing on AMD cards.... LOL!

how much u getting paid by nvidia to shill for them on random forum posts lmao

To finish up the post, I actually can't remember how I got it working. I think it was actually a vulkan related thing maybe with the 32 bit libs... The command MASTIAN mentioned in the first post did help me find it though. I don't have AMDGPU-PRO installed and it runs fine on the regular AMDGPU driver, just needed some tweak i sadly forgot

He's probably running some low end crap nvidia card anyways.

On my 6800, zero issues with Ray Tracing in Q2RTX.

I didn't realize the 3070 RTX I have paired with an i5 12600k and 5200 DDR5 ram was low end crap! Keep "Tweaking" the game guys, so it runs "Just fine!" On your AMD trash with no viable Ray Tracing solution.

Yeah, unless you had a 3080 you're not beating my 6800, even if it was a 3070 ti. Run along kiddo.

Let's both go head to head in a Cyberpunk 2077 benchmark, or Metro Exodus. Turn on some DLSS and ray tracing and we'll see who wins. (Spoiler alert, your card has no value for the future, much less the present in exciting game titles)

i will never be a tru MLG gamer... not enough FPS's :c

I was gonna look for a solution myself and ask you to let me know if you remember how you made it work, but luck has it I don't have to. :P Raytracing for AMD cards is enabled by default in Mesa as of version 22.2.0, which appeared in my distribution's repositories today.

Damn. I have Mesa 22.2.0-rc3 (Linux Mint) and still no dice on ray tracing for me. Only game I have currently is Quake II RTX. Were you able to successfully test any games after updating?

Output of vulkaninfo

For the errors, I found https://stackoverflow.com/questions/65512916/running-vulkaninfo-returns-error-vulkaninfo-h477-failed-with-error-initializa suggesting my GPU isn't supported (RX 6900)...? That would be weird. Further critical thinking & research reveals it may be an issue of trying to load 32bit libs on a 64bit system. Not even sure those errors are related to this issue or not.

Cheers.
