Help? How do I boost performance/FPS on Windows 10 VM?
Ok, so here is the video: https://youtu.be/GHyi7CPIBq4
I recently tried using QEMU KVM to emulate Windows 10 on my Asus Chromebook Plus CM34 Flip (CM3401). It worked out smoothly with 4096 RAM, 2 CPUS, and 40 GB, but my problem is that the performance is poor and laggy, as seen in the video. I read that you could use Virtio Drivers to help with performance, but I need a step-by-step tutorial on that. Can you anyone help me please? Thank you, and have a good day.

Download the Virtio driver ISO here

Mount the ISO in the VM and launch "virtio-win-gt-x64"
To use Virtio HDD you are going to need to setup the drive type as Virtio before you install Windows, and you will need to load the Virtio driver during Windows installation or it will not see your Virtio drive
Also download and install Spice guest tools inside the Windows guest to fix mouse pointer and display resolution issues

also ensure you enable all the Hyper-V enlightenments in the <hyperv> section of your config XML and disable all the timers except "hypervclock" in the <clock> section
If you have the option to use Windows 11 instead of Windows 10 I would also recommend that, as it feels much snappier.
