So I can put them on max pri renice, along with reniced X and app. And everything else on idle priority. So to make the app run at max efficiency, and not be starved by kernelthreads waiting. (Or any other consideration, for giving maximal cpu to app. Even small tweaks.) To read my research so far, (and I have done much, about 2 years of tweakinŽ on and off.) Please see http://paradoxuncreated.com/Blog/wordpress/?p=2268 Main points, no highres timer, 90hz timer, + a lot of smaller tweaks. This makes an amazing linux-desktop, for gaming, video and audio. The popular computer for everyman. Also boosts performance, for resource-constrained systems. For more advanced hacking, one could also get in there, and make several HZ timers, extremely low ones, for the components who only require that, and 90hz for video-components, for instance (low video/frame jitter), and higher if anything should require that. Also system-wide, software should be synced to hz, if required for lowest jitter, such as animations and videoplayers, and videoplayers automatically change refresh rate to a multiple of video framerate.
