<div>Hello all!<br></div><div><br></div><div>I'm trying to get pci passthrough working to play games in windows 10, i have everything set up but my gaming performance is poor, maybe 30% of bare metal with lots of micro studdering. I'm wondering if there's any glaring problems in my setup. <br></div><div><br></div><div>amd fx 8320<br></div><div>gtx 770 (passthrough)<br></div><div>host gpu<br></div><div>Linux Arch 4.1.16-1-lts #1
