I tried out WinXP with the standard HAL and the in-kernel APIC patches. I did not see any appreciable improvement in multimedia playback (video or audio). I still get the same amount of jitters. I've tried with and without -tdf too. So far, the smoothest play back I've gotten is using the ACPI HAL. Can you point to a particular example where you see an improvement? Perhaps a divx or movie trailer that is better with it than without it?
