I got my new HD6870 yesterday and put it in my PC. Played a brief bit of COD last night to see what it was like and had no problems.
Tonight I put Fallout 3 on to carry on with that and as soon as I got into the game I had lots of weird lights and graphical corruption. I took some screenshots in game but when I viewed them afterwards there was no corruption. After I quit Fallout it was still weird in Windows when I sent my mate a message on MSN and had bits of text missing.
I rebooted and its been fine since. Even in Fallout! I'm running the 10.10 drivers and I did have some issues with them on my HTPC.
Any ideas or is my new graphics card faulty?
