Are you playing on a computer from 1995 or do you simply refuse to turn down your settings if your FPS is low?
uh, no
when tf2 first came out I was averaging over 60 fps on high with 8x AA
nowadays it stutters constantly and the FPS is horrible, and i've
upgraded my specs since then
if I can play MWLL or X3TC on (respectively) low/medium and high settings, i should damn well be able to play tf2 on high with no AA fine
