Help with games Vista 5840 + Asus GF7700 in A8Js

Hi all. Got my A8Js saturday, and its growing on me even if I have some complains. Installed Vista on the 2nd partition. Build 5840, pre RTM, not RTM. I installed the nVidia 96.85 drivers at: http://www.laptopvideo2go.com/forum/...howtopic=11477

Vista, Aero works very well. Almost as quick as XP, very quick and smooth. Google Earth works excellent on it, Office 2007. BUT my games do not work:
- Half Life 2 has artifacts all over, surfaces without textures or flashing, etc.
- Prices of Persia Arena of Time: menu partly not showing, program with tons of artifacts, very bad performance.
- Doom 3, buggie, black screen when entering level, Alt Tab results in distorted screen (a fourth of viewing area shown, etc).
- Far Cry performing very bad, crashing.

As you see, not much working in the 3D part.

Any suggestions on this, anyone has their games working under Vista and the A8Js? Or stuff just not ready yet as OS is still not out on the market fully - I have to wait for nVidia to finish their stuff. Was not expecting this, I thought drivers would be mature enough to run them well - maybe not score as high as XP's on benchmarks, but work well enough.

Thanks,
