I can't seem to connect to that site to download those drivers.
However I'll go ahead and try to test the 14.21 drivers, I'm currently at 14.10 (I haven't really had a chance to test the card because I've been too busy to play games).
BTW, my driver info for GMA950 shows 14.10.4670. According to Intel, that's actually 14.24 for GMA950.
You can see from the Readme file. It says:
Graphics: 14.10.4670
HDMI Audio: 5.10.0.1014
(Not sure why they show audio driver version as it should be a seperate driver, not that important for us anyways)
14.21 is actually 6.14.10.4624.
I suggest you test the older versions of 3D Mark like 2001 or 2003. The scores aren't important now as the drivers aren't complete, and if you can't run 06, run 05 or 03. Check out what the fillrate for the card is on the test though, it should be same across all 3Dmarks(since its measuring the same thing).
Hope that helps.
