This is to correct my prior thread. I had been doing some work with Windows 8.1 for the upcoming Jaguar music server product. I held off on Win 8, because nobody liked the interface for a desktop machine, but 8.1 corrected that problem a bit.
After a few evenings of optimizing the OS I was alarmingly not able to get the latency below 1,000ns, when I would have expected it to be in the tens at that point (thus my post post that it had issues for high quality audio playback). However, AudioArcher pointed out that the website for the DPC Latency software I was using for measurement indicated that the software was not updated and did not work with Win 8.
I switched to Resplendence LatencyMon, which was updated for Win 8 and while not as quick and easy yields a lot more information. Below are the results for the comparison tests I did between Win 7 and Win 8.1. The figures could be lowered substantially with BIOS optimizations; this was with the default BIOS settings, but everything was the same with both measurements, I just switched the drives on the same machine. Win 8 has several new services that are required for stability or cannot be defeated in the Services menu. I had about six running in Win 7 and fifteen running in Win 8, but it may be possible to turn off a few of those fifteen in the registry (depends on whether it impacts the stability or bootability). In-short, they look very similar when comparing the average latency, which is where I would focus (note that this does not indicate how the two would compare in an unmodified state). Win 8 should be capable of equal or better performance as Win 7 after it's fully tweaked.
Here are the measurement results:

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:01:01 (h:mm:ss) on all processors.

The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
