Any help on how to fix it is appreciated.
Can you try running Windows in a Selective Startup and see if that helps at all:
If that doesn't, check that your graphics adapter drivers are up to date:
If you still get errors after that, can you try resetting the Interface options in-game back to defaults, then see what happens?
I wouldn't call it an error either, it's just something that's really really annoying to play with and it's hardly worth logging into the game with that studder.
I don't really know what's causing the stuttering, it's only happening when you turn your character around while holding mouse2 or using keyboard turning. I don't really use that so, I only see this happend when I hold mouse2 down and "spin" around. So it could be a problem with they're mouse / look options, idk. It's freaking annoying, and it should be a fast hotfix for it asap!
Instead of enjoying MoP to its fullest with a new graphics card (even a blizz employee called it awesome and said it should run the game perfectly) all I've been having is more and more problems...5.1 adding the most annoying one so far, the character flickering/stutter turn issue.
That tells me it's not my comp that's wrong, at least. Both these these setups ran WoW perfectly pre-5.0.4.
Can you let me know which mouse you're using?
As well as which keyboards you've got? This'll help us gather more info on this issue.
Also, can you try repairing the game client by removing the wow.mfil, wow.tfil and wow.pfil files found in your World of Warcraft folder, then running the World of Warcraft Launcher, then seeing if that helps at all?
Please let me know what happens, as well as the info requested above. Thanks!
I tried to remove the wow.mfil, wow.tfil and wow.pfil files then running the launcher, that didn't change a thing either
I'm currently using a "Steelseries 7g" keyboard and a "Zowie EC1" mouse.
