Subject: [Xen VGA Passthrough] Performance of AMD Radeon HD 6450 in Windows 7 HVM domU Poorer Than in Bare-Metal Windows 8.1 OS

Hi,
I have got VGA Passthrough working with AMD Radeon HD 6450.
However, the performance of AMD Radeon HD 6450 in Windows 7 HVM domU is
poorer than in bare-metal Windows 8.1 operating system. Please refer to
the 3dmark basic edition 1.3.708 scores for AMD Radeon HD 6450 in both
Windows 7 HVM domU and bare-metal Windows 8.1.
3dmark scores for Windows 7 HVM domU:
http://www.3dmark.com/3dm/3995208
3dmark scores for bare-metal Windows 8.1:
http://www.3dmark.com/3dm/3996885
Why is there such a great disparity in 3dmark scores for AMD Radeon HD
6450 in Windows 7 HVM domU and in bare-metal Windows 8.1?
The performance of AMD Radeon HD 6450 in Windows 7 HVM domU is not even
near native.
Is it possible for developers to improve the performance of AMD Radeon
HD 6450 in Windows HVM virtual machines?
Thank you very much.
