Hi, can you please check how is it working the same Project in X2 compared to X3?
 
On my system X3 its eating more cpu! I tried like 4 diferent projects, with diferent plugins, and all have the same CPU increase on X3
 
On the same project my CPU Reading is more or less like:
Sonar X2: 27-30%
Sonar X3: 37-40%
 
Thats about a 30% percent more CPU usage! This happens in all the projects I tested.
 
Presing "E" for bypassing every plugin for checking that its not any plugin increasing it...and it looks the same increase:
 
Sonar X2: 15%
Sonar X3: 20%
 
I already deleted the AUD.INI file as suggested in another thread...but nothing changed. And of course I checked that all the settings are the same on X2 and X3..buffer size, bit resolution etc.
 
Is this happening to anyone here? Can you please chek it? 
 
Just open the same Project on X2 and then on X3, and while playing just check the cpu% on the task manager
 
This is driving me crazy, because I was always freezing tracks when Im getting near the CPU limit (for not hearing tha typical pops a crackling) , and now, projects that play perfect on X2, on X3 they are on the limit and some "pops and cracks" are appearing!
 
Thanks

I seem to experience the same issue. Complex projects that ran using a certain buffer size in X2 require an increase in buffer size to run in X3.

Do you guys have any screens shots or projects you can supply for us to take a look? I like peaking under the hood :o)

Hi Dan,
 
Do you mean a screenshot of the task manager?
 
I will try to do it and post it here.
 
I just tried to compare it on another computer, and it was exactly the same... about a 30% more CPU usage. Its innoteceable when you dont push sonar to the limit, but my projects are very VST hungry and I need to be in low buffersize latencies..so the cpu many times reachs the limit.
 
Just asking, you dont see the same behaviour with any of your projects??
 
Perhaps it has to do with the new options added to sonar X3 compared to X2...but it would be a shame to loose this 30% of power
 
Please, can somebody try to test it?
 
Thanks!

I'm not trying to disrupt this thread... but I have to say the opposite is noticeably true for me.

 
Dan,
 
Cakewalk support are asking you to send them the contents of your project folder to them (e.g. as a zip file)
 (They want to load this up in their offices to see if they can recreate the issue their end)

I have also observed higher readings on Sonar CPU meters, interestingly also when play back is stopped.
 
I wonder if that has something to do with recent changes to FX tail handling and/or VST3.
 
Always Stream Audio Through FX. If any tracks or buses contain active plug-in effects, the audio engine will be activated and stream silence through the effects, even if the tracks have no audio data or Input Echo enabled. You will typically only disable this option if you want to conserve a bit of CPU processing if you play a project that contains lots of empty audio tracks with effects. There are several benefits to having this option enabled:
- Any effect with a “tail” (reverb, delay, etc.) will finish playing when playback is stopped.
- Effects will respond to automation envelopes, even on empty audio tracks.
- Many plug-ins do not update their UI properly until they receive audio input.

Hi Dan,
 
I will test it with one of your Sonar demos...so there will be no need to send you a Project, and I will come back to write here my cpu readings in sonar x2 compared to sonar X3 (with exactly same buffer size)
 
Thanks
 
 
 

Didn't we have a thread where CW said to delete the AUD.INI in X2 and let it rebuild it.
That did it for me as well.
In my situation, I did not have more CPU usage in X2 but, less CPU then X1.
Needless to say, softsynths play even better.

Awesome, anything that we can get would be great.
