I noticed lately with all these tweaks and ex frame rate limiter and all that my rig runs nice but won't go in full screen mode, and if i'm running 30 frames and put in in full screen she drops right down to 15 frames which is 1/2. i kinda noticed some thing was out of wack when i undocked the over head panel of the level d 67 and when i dragged it up to my 2nd monitor,she all dropped to 15 frames and the whole upper panel stayed black only. So now i just put it in full screen and she locked up solid.Must of done some thing along the way to upset this little critter, but in windowed mode i'm real happy with my rig but some things out of wack. Any thing i Undock and drag up to my upper monitor she's all black and drops to 15 frames-- Umm any ideas??

Confirmed.The second monitor is the culprit. You'd have to ask ******* but I think you will have to double the frame limit in the FPSLimiter BAT file.

Experimenting with what you said looks like your right.
