i just lately installed a Nvidia 7800 gs GPU to support the game Arma II. i downloaded the demo and it works fine with the card but the graphics are terrible. it's like i cant see 50 yards in front of me because the secnery is so terrible. i was wondering if anyone knows is it my GPU that's causing this problem or is it the fact that the downloaded demo just isnt that great. if anyone has any insight please help me.
