If you are using Hyper-V on a workstation machine with a high-end or consumer graphics card you may have noticed some performance problems such as short hangs or glitches especially when running graphically intense workloads.  The reason for this comes down to part of how high end graphic cards accomplish there performance conflicting with part of how Hyper-V accomplishes our performance – it’s comes down to high TLB (translation lookaside buffer) flushes

There is a KB published regarding this issue at http://support.microsoft.com/kb/961661 if you want to read more about it.
