I just put together a new machine, i7 950 with a 560 Ti gpu with 6gb of 1600 ram. Everything running at stock currently.
I copied the wow folder from my m11x c2d with a 350m gpu.
I went to play on new desktop and it was super choppy at the same settings. I renamed the launcher and config .wtf's and redid everything and still had issues with bad frame rates. (Doing lateral 360's were the worst.)
I restored the old config and launcher .wtf's. I then made a shortcut to the wow.exe and renamed the target to include -"d3d11" and now it runs perfect.
Graphic drivers are up to date from nvidia website.
However i cannot bump up the settings to high or ultra on some items, and the graphics slider bar is red beyond 'fair' just like it was on my m11x.
I manage about 60 addons across 4 character and would prefer not to redo all their ui's and would prefer not to delete the entire WTF, Cache, and addon folder if possible.
I dabble in IT and am currently researching the issue, thought I would post here in the mean time.
Thanks for the help.
