I just installed FSX, and it just won't work with my GEForce FX5600 with 256 MB DDR.I get the dreaded error message:"Invalid Hardware or Driver Detected:Flight Simulator is not working with your video card. Verify that you have the latest drivers installed for your video card." Well, duh.What is the minimum video card required for FSX?I have driver 93.71,the latest DirectX, and my 3DMark score is 2274. dxdiag can not "see" the memory (!), but the tests pass, anyway.What the heck? Anybody else seen this problem?- Jeff

Hi Jeff,I do have the same card with the same amount of memory.The latest driver, after a FULL uninstall form previous NVIDIA drivers, i have is 91.47_forceware_winxp2k_international_whql.exeBut FSX did work out of the box at once.So the chipset or memory can't be the bottleneck.So maybe something else is bothering your PC.Kind regards,Gert from Holland

Thanks for the encouragement, Gert.How do I do a ''FULL uninstall''? Is there a special procedure?I would really like to get this FX5600 working again!- Jeff
