Hi!
I have a Sapphire 5870 and has been enjoying it for the last two weeks.
I have played Men of War without any problems and World in Conflict both runs great.
A few days ago I installed Operation Flashpoint: Dragon Rising. When I tried to play it I had a horizontal line on the monitor about 2" wide that was flickering.
I then tried to play COD 4 and there I had white dots flashing all over the screen when I tried to play. This was all done with stock speed on the card and no heat issues detected, I even had the fans running at highest speed just to make sure it wasnt a heat problem.
So I thought that this maybe a driver issue with dx 9. I installed other drivers without success.
Then I tried to run OFR and COD 4 and underclocked the card to 600 Mhz on Core and 900 Mhz on memory and then all the issues were gone.
I have 750w psu and used to run a 9800gx2 and a 8800gtx simultaneously so it should not be a psu issue.
The only thing left for is if it might be a problem with Windows 7 and the drivers but I havent found anyone with the same problem as I.
Any input on what might be causing the problem would be great before I return the card.
Thanks!
