Ultra low-latency in ubuntu 22.04

I should run a visual experimental project with Matlab or Python in which the time resolution is dramatically important! that's why I shift to Linux and use the low-latency kernel in ubuntu. but I thought there is an ultra-low-latency or something like that in Linux Nvidia settings, same as a thing in 3D acceleration in Nvidia control panel windows.

Is there any way that enables Nvidia ultra-low latency in ubuntu 22.04?

Low latency kernel has very little to do with low latency in the sense of speed. low latency means only that your sound/video buffers will be serviced before they run out of data.

If what you need is complete control of the CPU during your experiment, you should use a tickless kernel, which Ubuntu does NOT provide and run your experiment on isolated CPUs. Also you should get a non-preemptable kernel (server).

Coincidentally I just wrote an article about those last week.
