RDNA2 doesn't really have any "hardware accelerators" for RT anyways, just some extra intersection instructions, there is no tool to show it, either on windows or linux. Bad performance also...
It has exactly as many "ray accelerators" as normal compute units because they are the same thing. Anyways, it's up to the vulkan driver to use the hardware as efficiently...
Also, the bad performance in Persona 3 might not be because of RT at all but because of: https://gitlab.freedesktop.org/mesa/mesa/-/issues/6260#note_2272979 You can try to run it with `RADV_DEBUG=nongg` as environment variable...
Yes, you would add `RADV_DEBUG=nongg %command%` as launch option for the game in steam. Normal Proton has everything.
Did RADV_DEBUG=nongg change anything?
@nokia8801 I think this would be needed https://wayland.app/protocols/commit-timing-v1
It's normal that apitrace slows the game down a lot, the trace will also be multiple gigabytes in size. You don't need to disable dxvk when tracing.
At least since your Windows+DXVK results also seem significantly better than DXVK+linux, I would suggest that you report it over at https://gitlab.freedesktop.org/mesa/mesa as a driver bug. You could also double...
And this doesn't happen without dxvk?
> But even having only Steam in the background caused huge performance drops. Make sure to disable "GPU accelerated rendering in web views" in the steam setting as it's a...
