[SOLVED]linuxcnc Latency test ambiguous results

I need search and compile him or only apt-get?

There are some instructions here:

I have a nvidia 610 video card, should I replace nouveau with the proprietary nvidia driver? (I already did it in theory)

I don't think the video is an issue as it would show up in the generic latency tests.
 

NVIDIA proprietary drivers do not work with RT kernel and neither do new AMD drivers.
Most of the time NVIDIA cards will cause latency spikes and should not be used for machine control, but i have plenty of GTX1060 and GTX1070 that are usable with NOVEAU drivers, older ones will mess latency badly, and even the ones i have on some motherboards do cause issues, so it's a cr@p shoot.
First, fix the ethernet latency, disable power saving options in BIOS and hyperthreading and TPM and..., then we can see what still needs to be done.

no packet loss this time with r8168!! thanks !

i have system with the nvidia proprietary driver i need to go back to nouveau?
