Installing Hyper-V core causes video playback problems

    Question

  • I have tried several times to install Hyper-V core from the install/uninstall Windows components menu in addition to Hyper-V management tools. Each time the installation was causing inability to tune media decoding and measure video playback performance during Windows experience index assessment. Specifically it affected the H-264 video codec.

  • Because Hyper-V is a hypervisor, all the running OS's are effectively virtual machines including the host OS. This is quite likely to impact on the overall performance of hardware specific functionality like video acceleration, which probably accounts for what you are seeing.

  • Hyper V affects the low latency applications like gaming and watching movies etc. That is why its not recommended for home users.

  • There is no impact on video playback itself, just on the measurement of the Windows experience index. I believe the reason for it is the same for the host operating system as that for the guest operating systems (virtual machines)
