Recently configuring WSL for Linux kernel development I enabled hyperv
bcdedit /set hypervisorlaunchtype auto
Sometime later I noted frame rate reduction in a few games, ran 3DMark to spot check and to my surprise I noted a 14.3% reduction in GPU performance.
Disabling hyperv and re-running that benchmark performance returned.
bcdedit /set hypervisorlaunchtype off
I then decided to try the same on Nvidia 3090 equipped dev machine. Performance remained consistent with and without hyperv enabled.
Machine 0 ‘Hulk’ – regression w/ hyperv enabled
- Dual Xeon 6154
- 192GB RAM
- AMD 7900 XTX
Machine 1 ‘Atlas’ – no regression w/ hyperv enabled
- Xeon 3495X
- 256GB RAM
- Nvidia 3090 FE
Would someone be kind enough to attempt reproducing AMD performance regression with hyperv enabled?
