Default Re: Nvidia driver 180.60 will not install on kernel-rt

I'm very well aware of these two facts.

The time I benchmarked the rt patches about two years ago, the
performance loss was negligible, too.

You didn't specify that, either, so I have been that fuzzy on purpose :-)

What I just wanted to say is: rt_preempt is about to enter mainline and
already worked fine along with the nvidia driver. If there is some regression,
then I'm interested to get that fixed. I currently don't have the need for
sub 30 microseconds hard real time requirements, right now, but in case
I urgently need it, it would be good to know that it is still working fine.
