It might be potentially usable for GetTickCount() which has resolution
around 10-15ms (though dangerous probably), but
QueryPerformanceCounter() is designed as higher resolution timer, every
game is using it and expects better resolution. 15-16ms is a long time.
But proper Unix functions for getting high resolution time should
already be quick, they also end up getting time from shared memory pages
maintained by kernel.
