I am running 3DMark11 benchmark tests on a (guest partition) VM running on Hyper-V 2012 (Windows Server 2012 Datacenter edition b9200 with Hyper-V role) and finding large differences when compared with the results obtained by running on the root partition. Apart from the difference in score, the user experience is poorer on the guest: the videos are perciptibly jerky whereas on the root partition, they are fluid.
Can anyone suggest optimisations? Specs and results are shown below.
###START SPECS AND RESULTS
The host has the following hardware specs:
1. Intel Xeon E5645 (6-core CPU, 12 logical processors)
2. 48GB RAM
3. Nvidia GeForce GTX560 Ti
The root partition of this installation is running Windows Server 2012 Datacenter edition b9200 and has driver version 306.23 installed.
Benchmark results for the root partition are:
(a) Graphics score:4300
(b) Physics score:6612
(c) Combined score:4330
(d) 3DMarks score:4541
On the other hand, the VM has the following hardware specs:
1. 4 vCPUs
2. 4GB RAM
3. RemoteFX 3D Video Adapter
Benchmark results for the VM (guest partition) are:
(a) Graphics score:3856
(b) Physics score:3414
(c) Combined score:2084
(d) 3DMarks score:3491
