Left4Dead2 Visuals Multihack

I can barely have any addons in game that do not crash the game.

Without addons the game doesn't crash. And i can't figure out which addons cause the crash. Maybe this crash file will tell you something.

make sure in display setting shaders are set to medium, also I think lowering msaa helps too, I have many addons including campaigns and the game barly ever crashes if i lower those settings

Many thanks dude. Your suggestion has worked wonders!
