And so on. I have also noticed this using simple auto tune but found i was seeing those rises from 80-80khs to 130 ALOT less than with the settings im using now and also the fan speed would go up and down with short bursts of work followed by a lot of idling. Also when viewing GPU usage in process hacker it only shows crss.exe utilizing my gpu with the following string, but its still fairly minimal GPU usage.

%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,20480,768 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ServerDll=sxssrv,4 ProfileControl=Off MaxRequestThreads=16

Im in a core i7, 12gb of ram with a gtx 560 ti and using a proper power supply so the gpu isnt lacking.

Any and all suggestions or comments on what is going on and how i can remediate it fto get things a bit more steady would be appreciated. Thanks in advance.
