I've just found out something very interesting. Well yesterday I decided to fill out an RMA request because I pretty much gave up on this card. Today I packed the card in the box and reinstalled my 5770 to see how games played. The first game was Crysis because the first 5 minutes showed artifacts when jumping out of the plane. Amazingly, I actually saw the same exact artifacts in Crysis when I used the 465 GE. I just sat there in disbelief, wondering what the hell could be causing this. I then thought of CoP and the artifacts I saw when lightning flashed in blowouts (emissions in the game that kill literally everything). I ran the game at the part I saved right before a blowout to check for artifacts, and holy ****, they were there! The same horizontal lines that cut through the screen when some lightning flashed were clearly visible.
My 5770 has never been overclocked, modified, etc in anyway. It's ran stock since January when I bought it. Now I honestly have no idea what can be causing these artifacts.Edited by JPJ5624 - 8/18/10 at 8:36pm
