Hello fellow Linux gamer 🙂
There used to be an issue which resulted in getting higher and more consistent FPS with vsync enabled ingame. As far as I know, this has been fixed a few updates ago, but I’d try re-enabling vsync ingame when trying other changes, if I were you.
You can check if you have enough VRAM using `nvidia-smi` or `nvtop`. I’ve had some issues with 2 GiB of VRAM in the past (I was trying to drive a 3440 × 1440 monitor, though). I too have read some people play with similar amounts of VRAM and I understand that amount is enough on Windows, but that’s worth checking.
You can also check if a single of your CPU cores is used at 100% using `htop`. I’ve an older CPU with similar single-thread performance compared to a R5 1400 (it’s an i5-6500), and while it offers great performance ingame, it’s a performance bottleneck for some parts of the UI (the menus and the replays overlay — don’t ask me why it’s more demanding than the game itself).
One more thing: you can check if your CPU is being throttled because of temperature using `journalctl -b 0 –dmesg –grep throt`. Thermals and frequency scaling are handled very differently on Windows and Linux, so that could explain some differences if your box is getting a bit hot.
