Left4Dead2 Visuals Multihack

I was shooting my gun having rapid fire enable then the game crashed. No crash log either, which is odd, to say the least. To be honest, there may be multiple reasons that lead to a crash not just this. For instance, i went to the bathroom and when i came back my game already crashed to deskstop. No crash log. Also, the weapon info doesn't correctly. It's showing symbols and stuff instead of the weapon's name. For most of them anyway, ammo for instance, is displayed correctly. Also, i'm not sure yet, but some of the options, chams related i suspect, cause massive fps drops. Maybe some optimization issues? I don't know. Anyway, that's all i have for now. Unfortunately, i can't play and experiment since the game usually crashes after the huge fps drops, so i'm sorry i can't provide anything useful, but i'll keep an eye out.
