Interesting. In a bad way.
People with the gtx 4xx, 5xx. Have had a flawless experience with skyrim. At the very least, 9/10 people say they don't get the 64hz microstutter bug with these cards. Which is more important than getting 100fps vs 60fps. (mid range card vs powerful card)
With a hd 5xxx and 6xxx and 7xxx the microstutter bug is still relevant. The 7xxx has performance tweaks which give it a better fps, but still. Both single cards and multi gpu's suffer from this problem, it worsens when you raise the AA, raise the resolution, and doubles when you add second gpu.
After going through about 18-20 threads on the bethesda pc hardware forums, I have found that people with gtx 680's seems to be getting this bug. People who upgraded from flawless experiences with gtx 460, 470, 480, 560ti, 570, 580, and sli variants of the aforementioned cards – are complaining about it. It often feels like a downgrade with a much higher fps.
The reason I say 'bug' is because skyrim does not have 'normal everyday microstutter' – it has a special kind that gives you actual, physical, choppiness in specific areas of the game. It also is one of the worst offenders of a perception shift (real micostutter). – That however is not what this post is about.
The bug kicks in when the framerate of the game hits about 64fps within the game logic of what 64fps is, people often use framerate cappers – be it msi afterburner or something else – to enforce a limit of 59 or 60fps. Which mostly eliminates the effect.
I originally thought that getting a 120hz monitor or a gtx 680 would solve this 64hz bug in skyrim, because a: the gtx 680 is and evolved fermi, which seems to not suffer from this problem, and b: – in regards to the 120hz monitor, because it would bypass the offending refresh rate.
However perhaps the architectural changes, however slight, of the gtx 680, have actually put the 680 in line with the hd 6xxx/7xxx cards. Or perhaps it's the latest beta drive revision, and it will be ironed out.
Either way. I am going to sit back and watch what happens. Mostly because I am waiting for a gtx 690 and stock. Partially because skyrim is one of my favorite games, and I don't want to suffer from the same problems as before.
This might not be relevant to anyone who does not suffer from this bug, or who does not notice it. Regardless – i thought it needed mentioning. As for the 120hz problems, it seems the bug does in fact crop up when you go over 64hz. And when you go over 80-90fps/hz, the physics goes rather insane, and lot's of game breaking strangeness starts to kick in.
