Full screen I got my new 4800 series card last night and played with it for 2 hours before I got it to work right. Do not try and OC the 4870 1 gb card. It totally screwed up the driver and card. I had to take the drivers out twice to get rid of artifacts popping up on the screen and freezing it. I researched and it may be a voltage issue on the 1 gig cards. I also do not have a full screen for Far Cry 2 any more. According to the post I read it may be as simple as just hitting to keys mentioned in the quote above. Has any one else had any or all of these issues?
