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.
Sorry, I’m confused on what the question is here. Is it just that a Windows developed game doesn’t perform as well on another platform that isn’t Windows?
With Proton it should perform just as well, or better than on Windows.
There are some pieces missing (NTSYNC, Wayland HDR protocols, etc) but there has been significant progress is Wine/Proton.
It’s far more likely that there is a configuration issue or old software version than it simply being a “Oh, of course it works worse because that’s Windows software” situation.
Exactly! It should, from what I heard Wine/Proton/Mesa developers strive to keep performance as close as possible to native or if possible even surpass it. So every time game doesn’t run as well on Wine like it does on Windows there is something that can be improved.
I don’t know anything about programming GPU drivers but I want to help with debugging as much as I can.
That is a myth. There are all kinds of reasons why this may not be the case, but I won’t get into that. Let me just dispell that myth though.
The performance difference is way to big, and a weird CPU behavior. Most games run with very minimal performance impact on Linux. Some games can even run better on Linux than on Windows and I’m not talking about native versions. Most developers don’t care about Linux at all.
Currently 100% of my gaming is done on Linux. I only switch to Windows partition to test, compare and diagnose issues with Proton/Wine.
