It has to do with me changing the textures for Online campaign is fine. When I was using a 5770 I couldnt get it to run on high so I set the textures to low then the rest on medium. Now with upgrading to a 670 same thing but now it seems to run on all medium settings. Now all my other games are not giving me a problem what so ever. I've tried a lot of methods, drivers,new audio driver and different hdd. What's going on anyone know?
