As we say in the UK - This is doing my head in!!I have an NVIDIA GeForce4 Ti 4600 which works great - gives me around 20 FPS at KPHX with dense scenery. Just bought a Radeon 9800SE which constantly underperforms the NVidia. Looking at Toms Hardware Website which gives benchmarks and general FPS figures for various settings for FS9 I should be doing a lot better. Done all the usual stuff - used Driver Cleaner 3, changed the Video Driver line in the FS9 cfg file etc. Played around with various settings including the standard of setting all sliders to the left and then incrementally increasing.All I get is stutters and a framerate 6 - 7 fps less than the NVidia TI4600.As I said, Its doing my head in!I would greatly appreciate any views or help. Not sure whether I would go as far as parting with $60 for the FSGS solution though.Kev

I am sorry but you fell in a well laid out trap. The 9800SE don

Also if you indead have any problem run dxdiag and look especially what it says about your GART drivers. If it says AGP status not available is quite common when changing from nVidia to ATI as an example.
