I'm not quite sure how to describe this issue I have been experiencing. The closest thing I can come up with is that if you have ever played a game on a dual core CPU, but the game doesn't use both cores. So you have to go into the process properties and disable one of the CPUs in the affinity settings.

Basically what happens is that when I get into a dungeon, building, or other indoor setting, I almost always have my mouselook movements accelerated, and my character movements do the same thing as well. The feeling is that frames are skipped or something like that.

I also experience this when playing Minecraft, so I always run it with only one active CPU affinity enabled and then the game is smooth. In fact when I first started playing Minecraft I tried doing multiplayer. This was before I figured out the CPU affinity fix. Someone accused me of using a speed hack because when I ran around. If I only run on one core, then my movements are normal.

Just for the heck of it I disabled one CPU affinity when I was in a cave while playing Skyrim, and the game became smooth. Unfortunately as soon as I went outside I found that the video portion of the game would freeze for several seconds at a time, every ten to fifteen seconds. At times the freezing was even more frequent.

One other thing - When I started to play, I had no problems. I went to my first dungeon, through the entire thing, and didn't experience this issue. But then the next time I went indoors then the problem started. Ever since then I've been seeing it when I go indoors.

Hopefully all of that makes sense. Has anyone else been dealing with this? Is there a fix?
