I read the manual.

This old box pumps.
It’s unbelievable quick and 100% stable.
Everything works better than expected.
If gaming is a benchmark this old thing executes,
Rocket League, GTA V, Arkham Origins, Need for Speed - HEAT flawlessly.
I say this to give hope to those struggling.
I know how frustrating it is when your new to this.
My only advice is read the manual.
Use the Distro packaged nVidia Driver in most cases… but read the manual.

nVidia on Linux / Gaming on Linux / Everything on Linux is fantastic.

Thanks to the nVidia Devs and everyone involved!

So to my question.

I recently pestered Ubuntu-Debian Linux Champion Timo Aaltonon if he could please update the Ubuntu 22.04 libnvidia-egl-wayland1 package from 1.1.9 to the latest 1.1.12 release.

I was blown away that inless than 6 hours Timo Aaltonon had updated the new libnvidia-egl-wayland1 latest 1.1.12 release in Debian unstable which filtered to Ubuntu Mantic Repos.

I immediately purged 1.1.9 and installed 1.1.12 from the mantic repos…
After disabling the mantic repo I then upgraded kDE-Neon 22.04 from the user to release repo.
I’m also using the latest Mesa from Valves - Kisak PPA.

The result was pure magic.

A Linux Unicorn!

Some performance issues in Wayland have resolved.
(some are still there but appear to be reduced.)

The desktop and general experience seems to now have a “silky” smooth quality.
It’s hard to explain.

Obviously both the upgraded nvidia-lib and the upgraded plasma packages contributed but,

exactly what do these commits below contribute to:

libnvidia-egl-wayland1 1.1.12

Added support for version 4 of the Linux DMA-BUF protocol
Added support for EGL_EXT_explicit_device extension
Fixed incomplete window resizing regression from 1.1.10
Fixed eglSwapInterval when using DMA-BUF path

Linux DMA-BUF protocol

Q.My question is probably how these changes relate to kDE Plasma Wayland?
Maybe? Is there an improvement with webkit?

EGL_EXT_explicit_device extension

Q. Is this to help iGPU + dGPU systems? or CPU/GPU Processing?
I have no idea.

Clearly I need to read some more manuals.

Any and all constructive input is very very welcome.
