    Sorry to hear that. Modern OSs are very complex, and very sensitive to a badly coded device drivers, and obviously have never been tested on majority of hardware combinations. I guess your Windows has some badly coded drivers or a combination of drivers which influences audio signal travel (from game to soundcard).

    Also do not forget that LatencyMon is just a program. It can have bugs, and overall it was made for professional real-time audio solutions.

    Look at LatencyMon`s log (your first log posted here):
    See the parts in bold font - they are contradict to each other:
    - how highest ISR routine execution time (µs) can be 257.794706 if there were 2 ISRs with execution time 500-999 µs?
    - how highest DPC routine execution time (µs) can be 404.665294 if there were 25 (!) DPCs with execution time 500-999 µs?

    If its just audio, what do you have audio quality set to I think be default windows sets it pretty high.
    Maybe try DVD setting level or even CD level, maybe that can help.
