It's been worked on, but getting it right is very difficult. See the VST patches at http://sourceforge.net/projects/high-res-timers/ There are questions as to whether the overhead of constantly reprogramming the timer interrupt source is worth the savings. Plus there are hardware issues and assumptions about timer frequency in the kernel. These should be getting better with time. - J<
