RADV Ray-Tracing To Become Much Faster With New Driver Code
RADV Ray-Tracing To Become Much Faster With New Driver Code
MR: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/24587
tl;dr big performance improvement in ray tracing on AMD cards coming, with the dev claiming a 3x performance boost in Hitman 3.
You're viewing a single thread.
Wait, AMD can raytrace on Linux? All the games I play on my 6800xt have the raytracing graphics options disabled.
Edit: I'm an idiot, I forgot the 7xxx series has actual RT cores.
I think you have to start the game with some arguments to enable ray tracing. Atleast that's what i had to do to enable ray tracing in cyberpunk. Game crashed instantly after i turned it on though lol.
6xxx does support it, it's just slower than 7xxx. I don't bother because I don't want the perf hit (even with these improvements) as I care more about high refresh rate/resolution support but good to see nevertheless, particularly for future cards where performance will improve further.
You might want to upgrade Mesa too as I believe at least some of the RT options should now be enabled by default, but I haven't tested myself. And you can force it with env variables, as the other commenter suggested.
You've been able to enable RT on a SteamDeck with the native (Linux based) OS for about 5+ months now. Performance may vary and it's certainly not going to measure up to a 69xx/79xx series card, but it can do about 30FPS on Doom Eternal, at the native 800P screen which is pretty neat for a portable running an APU :-)
I case you want to try it out, the setting I've used in Steam was:
RADV_PERFTEST=rt VKD3D_CONFIG=dxr11 %command%
