You sure you got the right post?

Yep you mentioned that. I managed to fix it afterwork. My windows installed pre controller passthrough seems to kept crashing. I switched over to Seabios, reinstalled windows and everything is working like a charm! Thanks David for your help.

I tried this but didn’t work for me. Still went into eternal bootloop

Hey folks, I just setup my windows vm, trying to passthrough my nvme controller of my Samsung 970 Evo NVMe SSD to my windows vm. I am following spaceinvaderone's guide but facing some issues. here's my IOMMU group. Trying to pass group 24. IOMMU group 0: [1022:1452] 00:01.0 Host bridge: Advanced Micro Devices, Inc.

Thanks for the info, I realised in the end it seems like Windows Defender was taking too much cpu usage, was pretty good after that. Unfortunately I couldn't pass through my nvme controller normally, Had to activate ACS Override to do this.

My hope is just that the CPU will not bottleneck the gpu in any form. Hopefully that's achievable.

Hi folks, I am currently exploring to buy a new RTX 2080 gpu, but I wanted to make sure first that the VM CPU would not bottleneck the GPU card in AAA games. My vm specs are as follows: CPU: Ryzen 2700X, passthrough 4 cores, 4 threads(reported as 8 logic processor in Win10) GPU Passthrough: GTX 760 Storage: VM storage is on a unmounted Samsung 970 Evo NVMe 512GB When running Dota 2, I am seeing CPU usage at 100% 3.7GHZ and GPU usage at 90~100%. I have seen some people here that managed to setup a 1080TI with the s ame cpu distribution as me, just wanted some advice on whether I should proceed with this project.
