As I understand it there are only two cards that support DX10 right now and the rest are supposed to be coming out in March?I have an ATI X1950 Pro which says that it's "Vista Ready." When I run dxdiag it says I'm running DX10 (at least on RC1 it did).I don't think my card supports DX10, and Vista appears to have shipped with DX10. I read in another post that FSX on Vista will only work with DX10 and a DX10 compatible card...What am I missing? Is the DX10 that is in Vista backwards compatible, and I'm really just getting the functionality of version 9c?Thanks,Jim

Hi,Vista ready means that the card will run under Vista and it does. However, it is not DX10 ready so you are seeing nothing from DX10.Jimhttp://www.hifisim.com/Active Sky V6 Development Team Active Sky V6 Proud SupporterHiFi Beta TeamRadar Contact Supporter: http://www.jdtllc.com/AirSource Member: http://www.air-source.us/FSEconomy Member:http://www.fseconomy.com/

Vista does include DX10. But it also includes DX9.0L, a version of DX9 specially for Vista. There are no DX10 games, no DX10 features you are missing as all Vista display features run fine under a modern DX9-based card.Allcott

The DX10 runtime is present.Neither your graphics card nor any application are utilizing it.Vista itself uses DX9.0L
