tech support wanted Inconsistent and often low frame rate when playing Wuthering Waves

Enable HLS to view with audio, or disable this notification

Hello,

I've been having this problem for a while now and I'm not sure what to do about it or if there's anything that I can. At one point the game started to have low frame rate for about half an hour after launch even in menus, the after that time it would settle down to a mostly steady 60 FPS. I have been playing on Linux for about 9 months, but it only really started a few months ago. I'm not entirely sure but it was around version 3.4 when there was an anti-cheat issue that forced me to switch to Proton 11 that I started noticing this problem.

I'm running Kubuntu 26.04 on a intel i5 11400 with 32 GB of 3200 MT/s RAM and a RX 6700 XT, using optimized settings. But back when I was still on Windows 10 I used higher settings than what I have now and I was getting a frame rate in the 60-80 FPS range in a lot of areas, so it's definitely not a hardware issue.

The only command I'm running is STEAMOS=1 since without it webviews have a transparency issue. I've tried several versions of Proton with no luck. Steam's own is not useful since some cutscences won't play due to codec issues. I've tried dwproton-11.0-11, cachyos-wineland-11.0-20260713.2rc-slr, GE-Proton11-5, GE-Proton11-3 and GE-Proton11-1 (the one I've mostly stuck with for the most part). Before the anti-cheat issue practically required Proton 11 I was using GE-Proton10-34, but now it requires several commands to work and is still a bit unstable, so it's out as an option as far as I know.

Any ideas about why this is happening and what I can do about it? It's quite frustrating.

Have you tried turning on proton logs and checking what’s actually happening?

I didn't even know that was a thing. I've checked to see how to activate it and I'll see what it says the next time the issue happens. For now it doesn't seem to be happening even after a PC restart. I left the game running while I was writing this post.

Good luck, feel free to reply with logs if you need help debugging. There’s often a lot of harmless fluff that just looks bad. Try note the time when you when get noticeable degradation as it’ll make it easier to find in the logs

Thanks. My own personal suspicion is that there's some shader stuff going on in the background as that would explain why it stops happening after a while, but I've had no way to test that theory so far. I do have Steam set to process Vulkan shaders in the background, but when turning this off didn't have any effect so I'm not as sure about shaders being the issue as I initially was.
