Ah yes, GTA Online now has kernel-level anti-cheat – but only got it recently. It used to work.
I’m also on all AMD. I do play almost exclusively single player, so maybe that’s the main difference.
There shouldn’t really be anything about Mint to cause such different results – even though they’re both derived from Ubuntu, I’d be curious if your experience changed with something like PopOS (more designed with gaming in mind, so could eliminate some possibility of setup issues or similar).
I don’t feel bad. It’s a big number, but it was spread out over 20 years. I’m sure I’d be shocked at a lot of numbers amalgamated over 20 years.
