Not sure if this has been discussed yet and if so, I apologize but I thought this was interesting:
Ever since this last patch I've noticed a fairly significant drop in FPS w/ my 8800gt. A few minutes ago, while fiddling with some video options to see if the patch had inadvertently done some damage, I noticed an increase of 20FPS while the window was open. As soon as I closed it, my FPS dropped again. Seems like a reversal of the skill window FPS drop bug. Anybody else run into this?
NOTE: this only occurs while viewing the VIDEO tab of the options screen... none of the other tabs seem to have this effect.
