Skyrim is a very CPU dependant game, unfortunately Bethesda didnt do a very good job optimizing the game probably because they had to optimize for 3 systems.

Fortunately for PC gamers, unlike console gamers our hands arent tied, we dont need to wait until a developer decides to fix stuff.

Any PC gamer looking for better performance with Skyrim could try this mod:

http://skyrim.nexusmods.com...

It replaces many calls to functions that would have been inlined if the compiler optimizer settings were set to something higher than "off" with actual inline code that nicely fits in the five bytes the jump instruction was previously taking up. It also overwrites several functions, replacing them with SSE implementations instead of the very painfully slow original x87 implementations.

Reynod's link to the PC mod works well. It should be mandatory for anyone playing the game on PC because no matter what system you have you should see fairly significant performance boosts.

I for one saw a performance jump of 20 percent, which is pretty significant. The game was fine before for me but any boost in frames is welcome so even in a worst case scenario it is even more fluid than before.

MY xbox version still runs perfectly. I have about 80 hours in my game, and no framerate issues.

I'm about 178 hours in on my PS3. I get a little bit of lag in Whiterun and a couple of other places, but other than that it works great. Hopefully this patch will make it run smoothly 100% of the time.
