To read my research so far, (and I have done much, about 2 years of
tweakin´ on and off.) Please see

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.
Peace Be With You.
PS: I forgot the realtime sincs of drivers. HZ is really not an issue
to debate for me, 90 hz is sufficient, and only to userspace, right?
So yea, forget the talk on HZ.
Peace Be With You.
And "synced to hz" with regards to video, is the screen hz ofcourse, not
kernel.
Peace Be With You.
