I have been playing around with UbuntuStudio 14.04 for about a week now, it is a very nice "Distro" I would highly recommend it to people that are new to Linux and are interested in Audio / Video / Game Creation, as a very solid starting point.
There are however some problems with the Nvidia drivers, ( ATI Radeon, I have no experience there, however it seems to be the norm now to default these cards to the Open Source alternative ) Anyway's I have been using Nvidia as long as I can remember.
So here's the deal I found, as you more than likely know using a Real Time Kernel, and a Generic or Server, and perhaps a Cloud based one produce different throughput result's depending upon what your ultimate goal is.
For Filming in a Virtual World such as SecondLife, Open Sim or Video Games more than likely you are going to prefer the Generic Kernel. However for final mixing you will require a Real Time kernel.
So here's the problem, getting the Nvidia driver kernel to to work on both boot option's is a real exercise in patience. I did manage to get it working correctly, by re-installing the Nvidia drivers ( all of them related to my hardware / minus a few I just did not need, mostly notebook related stuff ) on both kernels and multiple reboot's. And here is one thing that keeps rearing it's ugly head. The SUDO user command substituting for ROOT, don't get me wrong here, it's a double edged sword, for folk's unfamiliar with LINUX, it helps in preventing them from screwing things up too badly. I know there are some workaround's such as FAKEROOT and CALIFE, but I require actual ROOT and CHROOT privilege's, if I'm ever going to get anything accomplished.
Is it worth the amount of time required to install a Standard Kernel ? I'm going to perhaps go out on a limb here, but NO ! I can not really see much of a difference in FPS ( and that's not First Person Shooter ) performance, at least on modern hardware.
