It can be fast in one test and slow in 49 on one generation and on another generation it could be faster on 10 and slower 40. Just the nature of complex software supporting various generation of hardware.

It is definitely Nouveau. NVK is just the Vulkan side of it. NVK is in a experimental level. I personally would not run it daily yet, ignoring the lack of some video features and dlss in games. They have made huge strides in the last couple years with it though,

Edit: He has been posting videos for a while now running NVK, btw.

Nouveau doesn’t support power/load reporting yet. Some games will work better than others. Just because it is comformant does not mean it will be fast either. Comformance comes first then optimizations.

That said, it could still be running on the wrong gpu, but i don’t know. My experience when I’ve tried it on my 4080 hasn’t been mind blowing performance, but much better than before all this work started landing.

Also, just a stable accelerated desktop on install. Basic home/office and web/media consumption use.

Regarding cuda, yeah never know. Probably not for a long while as one of the benefits of their current driver is that it uses the same codebase between linux, freebsd and windows, so they should have feature parity in that regard. There are definitely pro/cons for their driver though.
