I'm still waiting for some NICE optimization.
Every time I join SOMETHING (Casual,Competitive,MvM,Pub,etc...) I start lagging/getting big-ass FPS drops/game freezes,or even EVERYTHING at the same time for like 10-15 minutes. Before the MyM update it was fine. Maybe some FPS drops,but that was it.
Now I can't play properly with all the problems I get every time. Can't escape from an attack because the game freezes,can't kill someone properly because my fps drop to 12,etc.
Right now I'm just opening TF2 to see if I'm doing good with my maps. It's like i'm quitting tf2 (sort of). And that's something I truly hate: Stop playing something that I love.
