Do I have high DPC Latency issue ?

[beardo]

Hi, I was using thesycon.de's Latency Checker with 1,000 us, then learned this tool was incompatible with Win 8 and found the xperf solution later on.  I'm uploading my etl file here & wanna see if anyone can check what's my level of DPC latency ?  Or how to reduce it furtheer ?

Yes, DPC Latency Checker's usefulness is limited with Windows 8.

 

What problem are you seeing?  Audio dropouts / video stuttering?

 

There are members on this forum who are adept at reading performance reports.  I suggest the advice for gathering data will be very similar to that given in this thread:

So far seems no Audio dropouts when i connect my previous DAC to my computer, but just wondering if lower DPC could produce a better sound quality ?

 

Will read your link further,

till 512µs it is still ok. Values over 1024 are bad and cause drops.
