Hyper-V gimping management OS graphics card RRS feed

  • Question

  • Hello guys,

    I recently installed the WP8 SDK alongside VS2013, and as a perquisite it of course installed Hyper-V, after a while I noticed a pretty big performance drop in most of the games on my machine, games I used to run at a steady 50-60 FPS experienced drops to 15-20 FPS.

    This happened in almost all games, and almost all of them are recent ones that are confirmed to work with Windows 8 (I run the Pro x64 SKU), so I set about troubleshooting the issue, I found that with Hyper-V enable in Windows features, all the games underutilized my graphics card, using GPU Shark I found that most games never use even 35% of the card's capability.

    I un-installed Hyper-V, only to find out my performance levels are back to normal.

    Question is, is there a way to have Hyper-V enabled and not suffer this horrid performance drop? and why is this problem happening in the first place? (I know the Hyper-V doesn't work like Virtual PC when it comes to the hardware and drivers of the host OS).

    I seriously need to fix this problem since I need Hyper-V for WP8 app development, and I'm a serious gamer so I need my games as well.

    Thanks for your help in advance.
