SuSE s a fine distro! I ran it for a few years and don't remember many issues. A few guys in my LUG use SuSE today. The do because their employers are SUSE-Enterprise customers.
Well, if the guest VM runs on KVM with SPICE/qxl support, and the LAN performance is reasonable, I'm seeing 200+ fps with glxgears demos using openGL. My setup is this:
- Ryzen 2600 w/ $70 nVidia GPU as kvm server 16.04
- GuestVM running 20.04 ubuntu-Mate with qxl + SPICE
- Laptop running 16.04 sng virt-viewer SPICE client. Core i5-8250U/8B RAM.
- 2 GigE network hops between the client laptop and server VM host using cheap (15 gige switches). No wifi. No realtek NICs.
Octane 2.0 in the chromium browser was about 29,700 rnning in this environment.

I didn't do anything special. You can see the uptime on each system.
SPICE is the best performing remote desktop that I know, by far. The connection from the laptop, to the KVM server, that makes the SPICE client/server connection:
Code:
/usr/bin/virt-viewer --connect qemu+ssh://hadar/system regulus &
SPICE is not encrypted, however.
- Seeing 200-270 fps with glxgears over SPICE.
- Using x2go as the remote desktop, glxgears runs around 45 fps for comparison.
- Running with ssh -X glxgears gets around 32 fps.
- Running natively on the laptop, glxgears runs around 60 fps.
SPICE is faster than native! I think that is more abot LLVMPipe in 20.04 than anything else.
SPICE rocks!
Visually, I can't tell the difference for anything over 60 fps. The laptop runs at: 1920x1080@60.01hz.
