Ok, here's the problem: Whenever I go over the area marked with red, my FPS drop to 1-3 fps, and the mouse gets incredibly jerky!!!I'm using latest Catalysts 5.3, but I also tried 5.1, and the problem remained!Any suggestions would be appreciated!http://forums.avsim.net/user_files/110462.jpgAnd just to clarify exactly what I mean (the red circle represents where the mouse was located):http://forums.avsim.net/user_files/110463.jpghttp://forums.avsim.net/user_files/110464.jpg

BUMP! Doesn't anyone have ANY ideas?!?

Ideas..? Hmmm, great question, Word Not Allowed! Did you install any other software lately? Maybe something which relates to your browser? Have you checked the 'Add/Remove Software' section to perhaps discover any unfamiliar entries or programs you never use? Anything unfamiliar running under your taskmanager's 'Processes' tab? Did you check with the developer? Case you cannot get any support, perhaps try one of Sysinternal's tools, i.e. ProcessExplorer. Good luck and kind regards Jaap

This is an issue since I upgraded my system. I used to have Radeon 9700 and this was not happening. A friend of mine has X800, and it's not happening. And I have PowerColor X850XT, and it's happening! I'm pretty sure it was happening since the first installation of FS.
