Sonar 4 On Dual Core

Hey all- really enjoying the forum! I did a review of the new Athlon Dual Core cpu's over at SOS which you can read here:
To Smithfield Or Manchester- The Dual Core Review For Musicians
I always thought that Sonar was a multi threaded app but i admit i didn't properly investigate it and i'm wondering if there is a way to enable it on both cores- could anyone from Cakewalk comment on this? I am using WinXP Pro which views it as 2 different cpu's- maybe if i was using win XP Home it would only see it as one large cpu

Thanks for the heads up boogie- unfortunately even with that option enabled the cpu meter maxes out in sonar yet task manager shows only 48-50% useage

I must say that I got no further than your first line which was "Introduction
I have been an AMD user for quiet a number of years...." and I stopped reading. Have you been through 4th grade spelling class?

I must say Dale did someone piss on your corn flakes this morning or do you always make totally pointless posts??

Yep it's 4.03(the second release) but i haven't experienced any drop outs while recording yet- if i do there will be hair flying

Nope- its actually a constant maxing out to the point where the audio engine would stop completely, i'll post a pic shortly, im fixing a pc for a friend at the moment

I am using a Dual Core 4400+ on my system with Windows XP Pro and when I enable the multiprocessing engine...my load cuts in half. Not sure why you are seeing what you are seeing.

Do you use Producer Edition or Studio Edition- i know it probably makes no difference but i'd like to narrow it down. Also what is your current patch??

I am using the Producer Edition, patch 4.03. I have heard of problems with 4.03, but as long as I am not seeing them on my system, I didn't want to revert. However, I don;t think any of them had to do with multiprocessing. That should work. Without Dual Procs or COres, you would not even have the option to enable the multiprocessing engine. So something is wierd there...I wish I could help. In task manager, you can separate the CPU graphs to monitor each CPU....see what is happening when you are running sonar and verify that obth CPU's are in use.

Hey there. I see what you are talking about. I have seen Sonar report incorrect (or double) CPU usage on a couple of other occasions. I would be surious as to why that is. Do me a favor and try this fix that was suggested for a similar problem...and let me know if it works.

(From another post):

I think it was Ron Kuper who kindly wrote here the "workaround" - to add a "UpdateNowOnTimer"=dword:00000001 in the registry .. since then i always use that (on any version - i wonder if some computers "like" this setting less than others..here it's fine)

on edit: found another older thread about that- http://forum.cakewalk.com/tm.asp?m=28826&mpage=1&key=temperature烮

EDIT: However, it does appear that one CPU is bearing the entire load. That is very strange. If you ask me....it doesn't appear that the multi processing engine is engaging. Is there any difference between enabling it and disbabling it. I would try both, shutting down the program each time you change.
