Hello, for a while now I try to figure out very poor performance in Ghostwire: Tokyo when ray tracing is on.
I tried to run this game on both Windows and Linux and the RT performance difference is huge. (45 FPS vs 15 FPS).
My hardware is R5 2600 6c12t CPU and RX 6700 XT so not too old not too new. I was hoping for someone with the same GPU could confirm the same issue and/or maybe point to solution.
There’s also a few very weird things I also noticed that happen when I turn on ray tracing:
- When I move (or open game) the CPU spikes to 100% and game often freezes for a 2-6 seconds. CPU spike also happens when I break some objects or just environment changes. It feels like the issue is with textures loading but how could this be connected to ray-tracing?
- Trying to just hold still for a few minutes will result in normal CPU usage. GPU goes to 99% but power draw is around 150W. (Card under heavy load can pull 195W and it does so in Windows). But still performance is bad. No more than 15 FPS compared to running game on Windows 45 FPS with same settings.
- Very laggy in start menu. Like 4 FPS.
More detailed info about my system:
OS: Manjaro Linux x86_64
Kernel: Linux 6.13.5-2-MANJARO
CPU: AMD Ryzen 5 2600 (12) @ 3.40 GHz
GPU: AMD Radeon RX 6700 XT
Memory: 31.27 GiB
Mesa: 24.3.4-arch1.1
Proton: I tried GE, Experimental, Hotfix.
For perf deficits in rtrt with heavier effects (reflections, GI, AO), you may find some luck in leveraging AMDVLK instead of RADV. I don’t doubt the latter will catch up in good time.
I tried AMDVLK but then the whole PC crashed when launching the game…
Fingers crossed for RADV then.
