Qemu OVMF PCI Passthrough | Latency issues

Hello,
Im running a Winderp 7 Gaming VM on my Arch with PCI Passthrough executed as described in the Wiki. (https://wiki.archlinux.org/index.php/PC … h_via_OVMF)
The Passthrough itself is working fine but i got a very high DPC and ISR Latency on my guest.
Post #141 on https://bbs.archlinux.org/viewtopic.php?id=162768&p=6 is describing my problem pretty exact but im unable to execute the solving approaches he provided.

Kernel: linux 4.5.3-1
CPU: i5 4690K
GPU: GTX 770 2GB
BOARD: Asus Z97-AR
QEMU: qemu-2.5.1-1

Im running my VM without libvirt just with a script running the QEMU command.

Thank you for potential help.
