Passthrough not using dGPU #7

Open mani-rai opened 4 years ago

Hey guys,

I think I managed to passthrough my dGPU and vGPU (iGPU GVT-g) both. My system is Dell XPS 9570 (nVidia GTX 1050 Ti Max Q showing as 3D controller). I was receiving code 43 when I was using standard driver. Using windows DCH driver I no longer get code 43 error. Looked around, I should have no issue using DCH driver as well. However, when I run Heaven Unigine benchmark, the performance is very low. Benchmark app as well shows its using my dGPU. But when I looked into task manager, only iGPU is used. I saw no usage of dGPU.

I have no idea what's going on. Can somebody guide me here where to look at?
