The game plays great on the PC
and the graphics are FAR better than either the 360 or ps3. Its true at first it was flawed (dev build) but with the patches released it has come a long way. Me and my friends play 4 player co-op and have not had any issues at all sense version 1.20
There is v-sync and two different ways to enable it. First and easiest way is to just force it using your graphics driver. Second way is to edit the video.scr file. The v-sync option is there, along with all your AA and other advanced graphic settings. This is not hard to do just takes a little know how.
I NEVER use in game voice chat. They are ALL inferior to TeamSpeak and Vent. If your having issues with voice chat download TS. Its free. Its easy it install.
All the complaints made here are to just bash the PC.
They are all hollow and have no substance. And to still be saying the PC version sucks because they "originally" released the dev version is fucking retarded. It wasn't even up for 12 hours before they replaced it with the correct version.
Buy this game on PC if you know how to fucking use a PC. Otherwise get it for a console.
Last thing we need is more complaints about it sucking on PC because of the users incompetence.
