Brief FPS drops

Issues & Assistance
1

Hello!

I’m new to CachyOS, having recently migrated from Debian. While trying to set up a local AI environment, dealing with CUDA proved challenging due to updates. However, I discovered that CachyOS offers a pre-packaged Local AI SDK, which solved my issues! So far, it’s been incredible… except for gaming performance.

FPS Drops:
When playing any game, my FPS significantly drops for about 5 seconds before returning to normal. I’ve tested this across multiple titles:

• Detroit: Become Human
• Everspace 2 Demo
• No Man’s Sky

Troubleshooting Steps:

  1. Steam Flatpak with NVIDIA GPU launch commands:

    • I first noticed the issue here.
    • I considered that it might be related to Flatpak’s containerization.

  2. CachyOS Gaming Package + Steam Native:

    • Used the game-performance launch command but still experiencing frame drops.

  3. Followed A1RMAX tutorial for gaming setup:

    • Despite this, I’m still encountering the issue.

Any insights or solutions would be greatly appreciated!

System Specs:
• Kernel: Linux 6.10.9-2-cachyos

I ran the game (everspace2) as an example,
and waited for the frame drops to occur, going down from 70fps, to 50fps, to 20fps and then quit.

How doy ou launch games? You need to use prime-run.

Otherwise, try to disable the GSP firmware.

UPDATE:

I reinstalled cachyOS but swapped btrfs for ext4 - Ive had no issues since!

I had previously used: __NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia %command% as the steam launch command, and I had disabled the GSP firmware -

I’m unsure what the cause was for the fps drops, but swapping to ext4 has fixed it.

Thanks for getting back to me!
