No, it's not a hardware problem. It's a software problem (see the links
in comment #10).

Title:
Stuttering mouse movement
I see that my motherboard is nvidia. i am running off the radeon card.
should i experiment going back to the motherboard video and see if the
mouse problem is video related? the MB will be even older

Yes I would expect Xorg to be slightly better right now. For reasons
unknown as yet, moving the mouse in a Wayland session forces the GPU to
redraw everything which will slow it down and stutter more. But in Xorg
sessions the mouse pointer can move freely without the GPU having to
redraw anything.
I ran a bunch of configs
none of them had a very big load on the processors. gnome shell 15%pk although
eyeballing it, the stable mouse conditions look a little less(?)
natural boot: both wayland and xorg have stuttering mouse.
boot adv option: non low latency: both wayland and xorg have stable
Thanks.
Please also try:
1. Logging into both Wayland and Xorg sessions. Is one better than the
other?
2. Open a terminal window and run 'top'. Do you see any process with
high CPU usage during the problem?

When i use "advanced start up options" and use a previous non low latency load,
everything stays normal.

We're working on a few fixes in this area:

In the meantime I suggest trying the normal Ubuntu kernel, not
"lowlatency". In the past when I was investigating performance I found
the unexpected problem of the "lowlatency" kernel actually being higher
latency for graphic
