Inspite of i have a good pc i can't play skyrim with ultra settings. İ can play any other pc games with highest settings without any problems but in Skyrim i'm getting constant 60 fps usually but in many areas when i turn the mouse fps drops suddenly to 25 ~40 and its very annoying and makes the game unplayable.(Looks like huge number of objects or textures loading slows down the fps)
Have latest drivers and crossfire profiles.
I have similay problem with Gta 4 but i know that it's a bad codded game.

2 x hd6970 can't handle the skyrim @ultra settings ? I know people can play @ultra settings @ constant 40~50 fps with a way less powerfull pc's.
Like the above posters suggest, try running it on one 6970. Many times, the issue is attributed to crossfire/ SLI setups. Anyways, you really 'shouldn't' need more than 1 6970 to run it on ultra. Give it a shot though.
some very specific areas of the game are really heavy for rendering, if you wan't to fix that, drop the shadows down on level from ultra. this will maintain 50fps even on those areas. you can also set the AntiAliasing to 2x will improve performance too if the above don't help you.
the peoples who say that can play on ultra (with less graphics) with constant 40-50 fps didn't get to those areas yet, or have shadows set to high too.
