Game loses frames after being open a while on Linux

[clairdelune25247]

Hello, I am playing deadlock on Linux, I am using the native version with Vulkan. The game runs perfectly fine for a little bit, and then it will start running MUCH slower (around a quarter of the frames) after playing for a bit; I haven't been able to pinpoint exactly when the dropping starts but it's around 15 to 30 minutes after launching. After doing some looking on ProtonDB I saw other people complaining of the same issue, and my friend who also plays on Linux is experiencing the same issue.

If it matters, I am on Arch Linux using CachyOS' v3 repos, and my other Linux-using friend is just on CachyOS. I do not believe it to be an issue with my system as the problem has persisted across several system updates (kernel/driver versions, etc)

Below is my Steam hardware scan in case it's needed. If any other information is needed please let me know.

I'm on EndeavourOS with a 2080 Super and I have a weird thing where I have microstutters when my mouse is bound/moving the camera but fine if I press tab or I am dead. I'm also using vulkan


I thought the native linux client wasn't available yet? Running vulkan is using the Windows Vulkan api, not the linux version.

I've also noticed some logs in journalctl saying that I'm out of vram (8gb, playing on all low FSR3 2x) and nvidia-smi showing deadlock capping my vram at the end of the game but these are only when big freezes are happening.

No logs for when just the microstutters happen though.
