SHADER DETAIL!!!111
Apparently that's what's killing L4D2, i had all options on the highest setting, and Shader Detail was on Very High and i had Multicore Rendering enabled, after this update, i could no longer have my Shader Detail on Very High or High, only Medium and Low, which sucks because now L4D2 looks like it did before we got this sweet new processor D:
I'm not sure if the Multicore Rendering will stop my game from working as well, but i haven't turned it back on yet
now that the voices are working it ain't half bad the old characters sometimes give you items too
I saw you send me a game invite when i was playing, sorry i didn't accept it, i was busy playing The Passing while trying to see if L4D2 worked
I got more achievables though! :D
