The autotldr-bot only summarized the first page, so here are some more quotes. Basically, the performance was almost identical, with two notable exceptions.
Across a variety of demanding GPU benchmarks the NVIDIA R550 open kernel driver continued to perform on-par with the proprietary driver for these GeForce RTX 40 graphics cards.
While running Blender 4.0 the proprietary kernel driver seemed to yield slightly better performance. It was just fractions of a second but was rather consistently showing the proprietary driver having that slight advantage here, unlike in other workloads.
There was the small advantage too that during periods of brief downtime using the open kernel driver appeared to deliver slightly lower GPU power consumption than the proprietary driver.
Does anyone have an idea what’s the point with the proprietary driver now? Does it have any features missing in the open driver?
You have to use the proprietary driver with GTX 1000 series cards and older to get good performance. 900 and 1000 series cards are cucked with no re-clocking on nouveau because they require signed firmware.
The main difference for me is the inability to preserve video memory during suspend and hibernate. Without it, sleep and hibernate will cause all sorts of weird graphical glitches upon resume.

You’re right, the new open source driver does not support the 1000 series and older, only Turing (2000 series) and above.
And 16 series, but that is also Turing.
You can see the differences in the official README here: https://us.download.nvidia.com/XFree86/Linux-x86_64/550.54.14/README/kernel_open.html
