No Windows 7 WDDM 1.1 drivers for T60's X1400?

#1 Post by briansmith » Sun May 03, 2009 10:00 pm

Is there going to be a WDDM 1.1 version of the X1400 video driver? I found version 8.561.0.0 of the driver on the Windows Update Catalog but it is WDDM 1.0.

Even the default Vista driver (from *2007*) works, but I was hoping for better performance and especially better power/heat management.

Thanks,
Brian

You don't really need 1.1 driver as changes aren't that big and everything works just fine without it (and sometimes even better, as 1.1 drivers are in beta).

I did some more research. It seems that the advantages of WDDM 1.1 over WDDM 1.0 only come into play when the graphics card supports DirectX 10. The X1400 only supports DirectX 9, not DirectX 10. Consequently, as Don said, there's probably no advantage to having a WDDM 1.1 driver for the X1400.
