This could be an issue where the AMD GPU is only being used. I, like some of the others would suggest Linux Mint.

I hate to say this but we are in a post anti cheat world and have been for a good 5 years now. There is no anti cheat which is 100% effective and that’s probably not going to change. This is why game developers are focusing on single player and co-op content. I’m not going to go into specifics and make things worse, but yeah valorent etc have just as many cheats.
