Anyone with the NVIDIA GeForce Go 6150 should stick with Windows 7. The tx2000z appears to give up capability under Windows 8. I installed Windows8Pro x64 on Sunday and the Windows Experience Index dropped from 3.0 to 2.7. Specifically, the Graphics measurement dropped from 3.3 with Win7 to 2.7 with Win8. That was enough to make Microsoft Flight Simulator stop performing.

Since HP has pretty much abandoned us for driver updates, I went to NVIDIA to download the latest Windows 8 x64 update for the GeForce Go 6150 at
Drivers - Download NVIDIA Drivers . Using Option 2, I let NVIDIA identify my OS and graphics unit to suggest the latest driver. This was the result:

The manufacturer of this system requires that you download the driver for your GPU from their support site.
The GeForce M series and GeForce Go series notebook GPUs use drivers that have been customized by the notebook manufacturers to support hot key functions, power management functions, lid close and suspend/resume behavior. NVIDIA has worked with some notebook manufacturers to provide notebook-specific driver updates, however, most notebook driver updates must come from the notebook manufacturer. Additionally, the desktop GeForce graphics drivers will not install on Geforce M series and Quadro M series notebook GPU's.
Since the computer is 4.5 years old, HP is not supporting it anymore so I will probably need to reinstall Windows 7 to continue to use it for flight training.
