Hi there, I was looking forward to make a Windows VM for gaming inside a Linux Host. I’ve had not much success with my setup as I almost always had an AMD card with reset bug and other weird behavior in Windows VM. I ended with a 2080Ti for guest and a Radeon VII for host.
I made my VM on Manjaro for host and everything is working fine now.
I only have questions about UPS and how does it work exactly. I tried to search on the subject but I dont know if I understood well.
For exemple with this setup I can not get more than 40-45 UPS in any game when the game is running 120FPS+
I know UPS is only updated when something is happening on the screen but is it normal to only reach 40-45 UPS on this setup ? (FPS on LG is rock solid 144).
Of course the egl slow warning is showing up and LG is far from being smooth (stuttering etc)
My VM is plugged to my monitor on HDMI with a 1440p resolution 144Hz (instead of using a dummy adapter) and my monitor is switched to DP as it’s also connected on my host GPU. But Windows still thinks the HDMI monitor is plugged in.
I’m using Manjaro and last LG Host and client (Bleeding edge host) and last available client from AUR.
I’m using a X570 Gaming plus from MSI and a Ryzen 9 3900X and so my host card (Radeon VII) is plugged to run on x16 and my guest card on x4 (almost no visible performance hit over x16 and my VM runs almost as fast as my native Windows setup)
Here is my GPU-Z on my Windows VM (1.1 is only when no load is detected)
Is this the x4 that can bottleneck UPS ?
Anything could be done to improve UPS ?
What can influence UPS ?
The egl warning is about the host GPU not able to display frames as fast as guest is sending them ?
My goal here was to permanently move from Windows for gaming and having my VM in a easy to switch thing in my Linux host, what LG is doing really great, but it can’t be used to play high FPS titles and playing competitive FPS at 40-45FPS is not possible. (For now I use a DP switch to switch between my host and guest GPU output but the way LG is working is really nice and way better for multi tasking / switching)
Thanks in advance for your lights I hop I was clear enough in what I said.
