HiI am running Intel Core Duo E6850 3ghz, 2 gig mem, x1950pro 512mb.Problem is in windowed mode the screen updates around 1 fps. In full screen the update is ok. If I disable AA the screen in windowed mode updates ok but without the AA, obviously! Why is the AA slowing the windowed mode when my nvidia 7800 didnt? I need windowed for dual monitor!Also if I use Aerosoft AES or Active cam config menu or any other addin window it doesnt display on the screen. If I alt-tab out of fs9 then bring it up again I can see the menu in the centre of the screen flicker on then off quickly but it doesnt display.Any ideas please? I have tried different settings/drivers ie 7.5 to 7.9 official, NGO, tweaksrus etc and all the Traytools but nothing seems to help.thanksGraham

Hi Graham,After you installed the new drivers, did you also rebuild the .CFGs and re-installed DirectX each time round?
