Hi, first of all , great work on xp11... loving it so far BUT......
ive had this same problem since the beginning... today i did a full reinstall of the game... once ready, i started it up, chose my settings (no AA) and got 100fps, i tried to put AA to 2 and got 80fps, fair enough, but then i went back to no AA and i still get 80...... moral of the story, where did those 20fps go?
