I gave it some thought, I think that you are getting slowdowns because of some kind of a bug and not due to slow speed of the GPU.

I have actually daily-driven a MacBook Pro 15-inch 2009 with a GeForce 9600M GT and even at 279 Mhz core, it was usable on Manjaro KDE, animations were a bit laggy, but nothing compared to what you are describing.

I still remember trying kernel 6.7 or 6.8 and immediately seeing MUCH worse performance with constant lags. I have only consistently used kernels 6.1, 6.6 and 6.12 on Manjaro on that machine, all of them with decent experience. I would try some other kernel if that’s possible, but considering that you have tried 6.12 and 6.16 at this point, I am not too hopeful.

Oh that sucks. Other than that, I don’t have many other ideas, maybe get a cheap used ATI/AMD card, even if it is worse on paper, as they should be decently supported, unlike Nouveau.

Nouveau supports manual reclocking for Tesla, Fermi and Kepler GPU-s. You said that you have a GT 710, so it should be supported. There is a guide on how to manually reclock it --> https://github.com/polkaulfield/nouveau-reclocking-guide.

Yup, it happened to me, installing necessary vlc plugins fixed the issue.
