Left4Dead2 Visuals Multihack

what's your screen res?

2560 x 1600
Sometimes it feels like there's something with my addons. I mean without addons it doesn't crash, but whenever i install an addon, when i start the game i hear a crackling sound which pretty much cues me in into the fact that the game is more than likely to crash. But i cant seem to be able to isolate the culprit or the culprits.
I swear it's downright enraging.

I tried switching between resolutions but i pretty much met up with the same situations. However, i noticed across different resolutions that if i alt tab out then back into the game, the game crashes. Every, single, time. Why? No idea. I already cut down on the amount of addons i'm using. So far it seems be working, although, i didn't get to test too much. It's really damn stupid. There's something obviously conflicting with the multi hack. And i'm not sure what.

so i didnt understand, without addons it doesnt crash?
