Vista - Graphic Card - Nvidia Issues

Can someone at Microsoft explain if possible why the following:

1. Install Windows Server 2008 with latest Nvidia drivers - OK
2. Install Hyper-V - Terrible performance on Host system
3. Remove either Hyper-V or graphics driver - OK

I know you may say that Hyper-V is an enterprise class hypervisor etc but I
am running this on a system that helps with demos and training and that
system has an Nvidia graphics card. The performance issues are ONLY there
when the role is installed. All drivers including BIOS are up to date.

Thanks

TC

The problem is the driver software for the Nvidia card.

Hi Bill,

I have seen that one. I have raised a PSS call also as it would be nice to
understand why something is happening.

Thomas - all updates installed but thanks for the post

MS KB 961661
Video performance may decrease
when a Windows Server 2008-based computer
has the Hyper-V role enabled
and an accelerated display adapter installed
