Skyrim crossfire issue?

This update seems to have broken the game for me. Prior to the 1.4 patch and the 12.1 catalyst drivers my game ran very jittery. My FPS would be pegged at 60 but the game had horrible stuttering when i would be turning or running through tunnels etc. I run duel 6870's in crossfire. This would only happen when I would play Skyrim in crossfire mode. I found a workaround though where I could just turn the shadows to high instead of ultra and the stutter was gone completely. I had everything else maxed completely including AA and would get a solid 60fps.

I thought my issue was solved until this high res pack was downloaded. Now all the sudden my game has the same horrible jitter issue except nothing I do seems to get rid of it unless I run Skyrim on a single card. Tried completely removing all traces of my drivers and reinstalling the latest 12.1 catalyst package and CAP. Turning off the HD texture packs doesn't help at all. Even if I turn all the graphic settings on low I still get the stuttering. Nothing had changed on my computer except I downloaded this HD texture pack.


See sig for specs.

I have tried basically everything I can think of besides re-installing the game. I was hoping to fix it without needing that. Thanks for the help.
 
You can disable the texture pack if you're willing.

I get that horrible jittery-ness on mine as well. I run a single 6870. Previously I turned off mouse acceleration and that fixed the issue for me. But the last time I played (pre-texture pack) it was back and mouse acceleration fiddling didn't help.
 
Yea I've tried that already, it seems having the texture pack on or off has no effect on the issue. I didn't mess with the mouse acceleration yet so I will give that a go when I get home.
 
So it ended up being vsync that was causing the problem. After changing iPresentInterval to 0 in the Skyrim.ini file (\Documents\My Games\Skyrim) I now have no stuttering issues. thanks Maplehamwich
 
I have this same problem but doesn't disabled vsync cause physics glitches with you? Things fly all over the place and it's even worse when I have my dog follower with me. I get weird screen flashes as well. I'm really hoping for more driver improvements soon.
 
my 6870 crossfire issues only arise in skyrim when im in 1st person view sometimes, otherwise it's buttery smooth.
 
Mine's in first person with vsync on and in either certain lighting issues or certain artifacts on screen. Either way I fixed it with the anti-lag patch that limited the framerate and I also disabled vsync. Runs great now.
 
If you're going to disable v-sync, make sure you use some other program to cap your FPS at 60. Otherwise, like bboynitrous said, you'll start having crazy physics glitches.
 
This game has some crazy glitches. Some days I'll have the stutter issue (even on a single card not xfire). It's not really bad, just a fraction of a second stutter every 5 seconds or so.

I haven't seen the crazy physics issues, but yesterday while investigating an enemy camp my horse decided to go on a killing spree. It also had fun attacking Alduin during the time rift where you learn Dragon Rend haha.
 
Are you guys actually getting positive crossfire scaling? I lose about 10fps when I have crossfire enabled. I have to keep it disabled to get the best performance (it still runs nicely but I would like to get full use of crossfire if I could).
