On some

older 'nv'. I did not try the proprietary driver from Nvidia,
AFAIK it has latency problems as well.
while i heard rumors about latency problems of the proprietary nvidia
driver, i did not experience any latency issues. when i did some histograms
for the multicore signal processing engine of supernova on my nehalem
workstation, i was measuring a maximum jitter of about 10 microseconds.
unless you don't want to use the proprietary nvidia driver for political
reasons, it is fine to run it for low-latency applications ... but testing
it is probably better than relying on personal opinions ...
I use the proprietary NVidia drivers on Ubuntu Studio... very few, if
any, problems with latency or xruns here, and I am recording and
mixing just about every day on this system (including sequencing with
samples on a separate machine and syncing to previously recorded
material). However, I am using RME Multiface II and have disabled the
internal audio hardware, so YMMV depending on hardware and software
combination.
