I've always felt you get better performance with fullscreen, because that window has 100% focus. I also get input lag in borderless window (more noticeable in other games though).Is full screen better than borderless window? Ive auto had it set to borderless window.
Just a little gripe so far with how Geralt moves. He seems to take an extra step or two after you release analogue stick? Whilst ill probably get used to it and ajust, right now im finding it hard to accurately loot things or get on horse, end up fidgeting around the damn thing.
