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. -- Brett W.
