seems to be specific games, kingdom come deliverance (the original) stuttered & hitched badly on other distros, but cachy was 👌

I would remove all of the commands and see if the issue persists.

If it fixes it, add each command one by one until you find whats causing the issue.

If it doesnt fix it, at least you can rule that out.
