Hi, I'm using strong machine which with i9-14900 processor and RTX4090 GPU with Windows 11 Pro with hyper-v and GPU-P set on it. I notice when I use higher resolution 5120x1440 I getting on VM frame rate 10Hz. When resolution is 3840x2160 I'm getting 60Hz on VM.

With the same settings directly on host machine without VM, I can get 60Hz frame rate with 5120x1440 and 3840x2160.

Is there is any limitation which cause dramatic frame rate drop for resolutions higher than 4K on hyper-v VM?

    Hi Michal Poterek,

    Thanks for your post. Based on my research, generally speaking, you will always get a FPS drop when going up in resolution - it’s normal because you’re making your GPU do more calculations. If you’ve got a good enough GPU or the settings just right then the GPU should be able to keep going at a normal fps of either 50 or 25 UK or 60 or 30fps US (films are quite often shot a 50/60fps where as cheap low budget TV series generally use 25/30fps as you don’t really notice the two frames merge into one as much).

    Best Regards,

    Ian Xue
