Yesterday i add a autoexec.cfg to my Crysis 2 folder to get better Grafik and that work fine, but today i wanted to play Multiplayer and my Crysis 2 just crash after giving me an error box : "Crysis 2 have a problem". So i went to my Crysis 2 folder and deleated the cfg but it doesn′t help (and i also restarted my PC).

So what can i do now ?

PS.: This is my autoexec.cfg

It can be just coincidence, I use almost same config and it work fine. You can try to cleanup shader cache, but I not sure this helps.
