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! Graphic card is PowerColor Radeon X850 XT.Any suggestions would be appreciated!EDIT: This has been posted in the Hardware Discussion Forums, though not really many people read it. So I'm trying here, so hopefully someone will have some ideas!And just to clarify exactly what I mean (the red circle represents where the mouse was located):http://forums.avsim.net/user_files/111865.jpghttp://forums.avsim.net/user_files/111866.jpgThis is the area affected!http://forums.avsim.net/user_files/111867.jpgAnd one more thing, when in full screen, and I click on the panel with my right mouse, to open a menu for closing of the panel, there is aprroximate lag of 3-5 seconds, depending which panel.I don't know if this is a system problem or a driver, but I hope someone MIGHT have some ideas!

HiCant really help with the problem :(Just letting you know I have the same prob with the same drivers but different systemI do think it maybe a driver prob as I had a simular problem in the aircraft selection menu with some of the older drivers but with the 5.3 its fine.CheersWozza

Wozza, thank you for your reply. It might be 5.3 driver. Although, as I mentioned, I used to have 9700, and I tried it I think with 5.1 driver, which worked OK back then. And now, X850 with 5.1 has the same problem!

BUMP!

HelloThere are some new ATI 5.4 drivers just out now.Maybe you should give them a try.Cheers
