About GMA500 driver development
I have a simple question: will the driver for the GMA500 support WDDM 1.1? The hardware is DX10.1 capable, but lacks driver support. Vista GMA500 driver is not compatible with Win7, using it leads to a lot of bsod in many operations. With wddm 1.1 memory usage for the dwm hopefully will be reduced, and maybe will get a better 2d acceleration, useful for flash apps. As a last chance, if wddm 1.1 support is not planned, will wddm 1.0 Vista driver be patched to work well under Win7?

Is anyone aware of any progress regarding the above? Recent Win7 drivers release has made vastt improvements in terms of stability (no more BSODs), but performance is still embarasing (i.e. even Aero is very choppy).

For instance, IEGD driver (sadly only XDDM version is available) for GMA 500 almost doubles 3D performance comparing to the latests Win7 drivers (from about 900 points to 1800 points in 3D Mark 2001 SE). However, Aero obviously won't work on these IEDC drivers and also DXVA is broken.

Also, support for WDDM 1.1 is very badly needed - this should bring up significant performance improvement (2D acceleration, lower memory usage)

Any information would be really appreciated.

I couldn't agree more with you guys above.

Any information/updates on this topic would be tremendously appreciated.
