I'm sure you already know my answers
1) Are you seeing major random FPS swings? Yes
How low? Down to 15fps from 40-90fps depending on what I have maxfps set at (once down to 0, but believe that to have been a unique situation)
2) Are they interfering with your game play? Yes
How so? Because when fps drops there's a second or two of not being able to do anything and has proven deadly in PvE and PvP most of the time.
3) In what zones do you see these swings? So far I've seen it in all zones a level 1-34 character can (safely, to a point..lol) play in.
4) Do you have FPS issues in non-raid instances? Yes
5) Do you have FPS issues in Battelgrounds? Yes
6) Do you have FPS issues in 25/40 man raids? I don't raid (yet)
7) If you disable just nUI leaving all other mods active and repeat the same activities in the same zones under the same conditions, do you still see *any* FPS drop? No
Thanks again for your great support and great UI!
