I have just replaced my Nvida graphics card with a Radeon 9800Pro and setting AF & AA does not seem to have any impact on the jaggies either in windowed mode or full screen.I am currently using the drivers that came with card, shown as 6.14.10.6444.On the 3D tab of the ATi control panel I have AA set to 6x and AF set to 4X, AF method is Quality, texture and mipmap set to High quality.I have OK'd the settings and saved them to FS9 profile.Strange thing is, if I change the settings while FS9 is minimised and then restore FS9 the settings take effect and I can switch to full screen with the settings still having an effect.However if I then set FS9 back to windowed mode the jaggies are back but in windowed and full screen mode.If I close FS9 and reopen it I still have the jaggies.mo/bo is an Abit NF7 with the Nvidia NF2 chipset.Anyone any solution?TIA

Yep update to the latest drivers and it's solved ;-)Andr
