Also, yes Hugepages might be helpful too. Also, would you mind observing whether interrupts are posted when the GPU is in use in pass-through? watch -d cat /proc/interrupts Look at the bottom for PIN (Posted-interrupt notification event) and PIW (Posted-interrupt wakeup event).

If not you may need to dump and specify the ROM file for your video card. For me OVMF would hang unless I did this.
