Hi Guys!Now I have a problem as follows:- when I am in Full screen mode then everything is OK - FPS ~30- when I am in Windowed mode then FPS drops to 1-3 ...My config is:WinXP, FS9.1, ATi Radeon 9800 Pro - I use Catalyst v4.10 drivers, same problem with newest Omega drivers...Oh:FS: anti-aliasing UNCHECKED, T&L checkedCatalyst Center: both Smoothvision AAx2, FAAx2 ON, let application decide UNCHECKED.Same drop when FS decides on AA...It returns to 30 FPS only when BOTH AA in FS9.1 and AA nad FAA in Catalyst are UNCHECKED...It was OK before and now it is not- I can not identify cause and can not obtain 30 FPS in windowed mode back again...Please Help!.

i may be wrong but isn't windowed mode software rendering without hardware support, therefor all the rendering is provided by the cpu instead of the gpu.

Should be also handled in hardware mode...OK, my problem is solved as for me, but I don't know why :)I just simply reverted back to previous state using ghost backup of system patition (I've got one!!!). Now I have 30 FPS in windowed mode also!My hipothesis is that it would be corrupted fs9.cfg file...
