Well there have been some strides. Games using EAC (Easy Anti-Cheat) seem to work fine now. EAC tends to be more acceptable because it's well known that it shuts down as soon as the game is quit.

A lot of these other solutions like Riot's thingy or whatever Battlefield 6 uses, seem to enjoy (and insist upon) running even while the game isn't, which is positively sus.

So yeah in the case of Nprotect, I really don't know. I've heard on Windows it's pretty invasive and jank though, with the usual security assurance of "Lol just trust us bro."

It'd be neat if it would be contained on a Linux system but also...wouldn't that void the point? It seems they wouldn't be satisfied with allowing Linux players if that were the case.

The uncertainty is the frustrating part. =\
