So, I finally got Skyrim to run ok...decent I guess...with Xfire on with Ultra settings.

At first, I was getting horrible framerates outside AND inside as most others have had. As a probable result of needing a CAP from ATI for Skyrim. Also, I was getting the bad texture/decal pop-in problem and horrible input lag. Starting framerates were 5-15 fps outside and 15-20 inside.

I changed the settings to HIGH from Ultra (which was the game's recommended setting) and NO CHANGE in fps. I disabled Xfire, NO CHANGE in FPS.

I fixed the input lag with the vsync shutoff ini change.

I managed to fix the texture/decal pop-in problem by turning AA off in game and turning FXAA on. Viola! No more texture popping. Doing this also (no kidding as it disabled AA) improved my framerate indoors, which went from 20-30 fps to about 50-70. Still no change outdoors...

I have also downloaded that temp .dll fix from Radeon Pro and put it into my Skyrim folder. Doing this increased by fps indoors from 50-70 to 80-140 and fps outside from 5-15 to 20-35 still all with Crossfire on and Ultra settings (minus the AA)

Now my problems that I still have are:
*FPS outdoors svck...probably going to need to wait for the CAP for Skyrim from ATI to fix this...
*Shadows look HORRIBLE in some places...Extremely pixelated (Anyone know a workaround/fix for this?)
*Now that my fps indoors shoots above 100 at times...I will get temporary blurred screen lines (tearing?) when I run indoors or move the mouse too quickly. I tried the fpslimiter fix...but it crashes Skyrim upon startup (Anyone else get this to work?)
*Also, I have noticed mouse input is directly proportional to fps...outdoors mouse input seems a bit slow/laggy/delayed, esp VERTICAL movement. Indoors however, the mouse moves more fluid, but my vertical is INSANELY fast. Looking up and down is too quick compared to side to side...makes fighting
and searching for things a little sickening which I sure isn't helped with the super close FOV in first person (How to change this?)

If anyone has any helpful comments/fixes it would be much appreciated. Those others of us ATI Xfire users experiencing similar problems, would like to hear from you as well, perhaps we can find some common grounds.

Update to above:

I also tried Bandicam as suggested in these forums to limit the fps, but just like fpslimiter, it locks up Skyrim upon launch. Phooey...

On a side note, I did decrease shadows, which did increase fps all-around. At that point, on low shadow settings I was getting 30-80 fps outdoors, and over 140 indoors. Problem is I cant solve that stupid mouse Vertical acceleration problem for indoors...so I reverted my shadows back to ultra to limit indoor fps...GRRR

Can't wait for patches and new ATI drivers/CAP for Skyrim...

What is the temp .dll fix?

You need to download this dll and put it in u're skyrim folder in steamapps: http://www.megaupload.com/?d=ICEDIU66

It improved some performance for me. I read it is a workaround for Xfire users until ATI releases a CAP for Skyrim.

See this topic and send an email.

Well, haven't managed to change much since my last post...just went ahead and started playing as the game is playable...decently anyways. Outside is definitely worse. But anyways, Skyrim is just......

Gorgeous! So far I have just traveled to Riverwood and listened in on the conversations. The water, the sounds, the graphics are all very immersive...I can't wait to see it with Xfire working properly and the bugs in the game fixed...

Speaking of bugs, I also have the low sound that others have...clicking the "loud equalization" to enabled helped it. Hope they fix this too.

I LOVE lighting oil puddles on fire >

I had exactly the same issues to fix it I just put the game on high and turned OFF both Anti aliasing and Anisotropic Filtering OFF. and that seemed to fix everything
