Hey, just letting you know I sorted the issue, the thread I opened about it on the mint forums is here if you’re interested in more details: https://forums.linuxmint.com/viewtopic.php?p=2691196#p2691196

It turned out that the base mesa and mesa (extra) packages were duplicated on my system, so just uninstalling both of them and reinstalling only one copy fixed it. It wasn’t the mesa-vulkan-drivers though, but very similar to your problem. Your information did help me to the solution.

Thanks for your help!

Oooh, interesting, so you’re right that when I get the lag, there’s a lot of CPU usage. Also there was definitely a system update before it started happening - although I can’t say exactly when because I wasn’t gaming on this system for a few days.

I’m on Mint 22.1 and I’ve tried uinstalling and reinstalling through the software manager GUI, and I’ve also tried:

sudo apt purge mesa-vulkan-drivers
sudo apt install mesa-vulkan-drivers

None of that changed the problem. I also made sure I restarted the system.

Am I doing that right? Are there any other steps that I’m missing?
