RE: optimised WASAPI exclusive event c++ code

Hi SBGK,

Thanks for the response. I went to the jplay link you posted and found a lot of good information. On the first page of that topic I got onto this link which I found to have some great information:

http://www.computeraudiodesign.com/Windows%20Modifications/CAD%20Windows%20Software%20Modifications.pdf

I went through the entire document and did almost every suggestion he made. It took the better part of the day (including troubleshooting BSOD caused by one of the registry changes to disable services/drivers). I'm convinced it made a noticeable change for the better.

One question I have is based on your suggestion to:

"make a .reg file with the following

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl]
"Win32PrioritySeparation"=dword:00000018
"IRQ4294967294Priority"=dword:00000099
"IRQ13Priority"=dword:00000099
"IRQ0Priority"=dword:00000099
"IRQ8Priority"=dword:00000000
"IRQ22Priority"=dword:00000000
"IRQ1Priority"=dword:00000099
"IRQ12Priority"=dword:00000099"

I see you have IRQ's with the same priority. From page 29 of that pdf I linked above, he specifically comments that it's not recommended to have IRQ's with the same priority. using his guidelines, I did modify my IRQ priorities and had no issues. I'd be curious to hear your thoughts on using same priority level for different IRQs.

Thanks,

Bill
