Before this stupid update, I was averaging 300+ fps for tf2, but after it I am averaging 60fps and with a lot of noticeable lag. Does anyone have any ideas what may be the cause, because I can't play TF2 with this lag 
Donno if this is of importance, but the update bugged out and force me to re-download 2 gigs of TF2, twice.
