So the Catalyst problems in 1946 are back... Shame on you AMD (ATI).
AMD and some flight sims (unfortunately my favorite one's) don't get along. I bought the HD 5xxx series (5870) and it had major bug/performance issues regarding 1946 and FSX. It was OK with Eagle Dynamics products (Black Shark, Flaming Cliffs 2 and Warthog) and with WoP (demo only). Don't own RoF.
My HD 5870 broke after almost 2 years, send it back to RMA, and they've send me the new HD 6xxx series (HD 6950 1 gig). And once again I faced more problems comparing to the green ones (e.g. blue lines in the horizon).
