I upgraded recently to a Gecube HD3870 512Mb Radeon card. Frame rates are now brilliant, but I can't get anti-aliasing to work in FS9 or FSX (or any other games). The only game that gives me AA is Crysis (DX9 on XP SP3).I am using XP on an Asus A8N-E mobo, Athlon 3700+ CPU, 2Gb RAM, Catalyst driver 8.9 (latest one). I've tried setting AA in CCC, in ATI Tray Tools and within the games. No joy.I've also tried a clean install of XP SP3, ensured all drivers are up to date etc. I've also had no luck with AA on Vista SP1 Ultimate.Since Crysis is doing AA (but within the game's options), is it possible that the card itself is not doing AA, but relying on the graphics engine rather than DirectX / hardware ?
