[Solved] volume envelope causes stuttering

Besides other tweaks , bumping up to 1024 was the answer. Thank you everyone for your help.

Sorry, this is a highly technical long question and forgive me for taking your time.
When I change from clips to volume envelope my system stutters. I can work in that mode doing volumes, nodes, write fades in real-time with all my mixing plug-ins plus Omnisphere/ a few instruments in Play. But unless I flip the toggle back to clips it won't play stable. So, I am at 256 right now. Should I have to move it up to 512 or 1024? It's after the 40 tracks are done, synth programs open, waves plugs on most busses or individual instruments (acoustic drums of course-7 tracks)--mixing, but I often add strings/pads/layering after everything is mixed so like to keep the latency low. I could use my MOTIFXS88 strings then latency isn't an issue, but these EWQLGold Strings are pretty awesome. Anyway, I'll try it and post back. 16gb ram/forgot the chipset/cpu--it's an i7, but similar to Bob's system last time we talked about --hmmm-8 months ago? Funny that only going from clips to volume envelope do I have the problem. Anytime I toggle back to clips, it's a smoking machine (in a good way.)
 
 
Edit-P.S. Of course I can just bypass the bins while I do the OD's/sweetening, but then the mix goes to crap and it distracts me. I have tried switching the PDC button, and then no latency becasue of the delay compensation, but then you always have to flip it back to hear the playback in sync.

You have a lot going on in the project. I would definitely adjust your playback buffer to 512 or higher and see if that helps.

ah, the mouse resolution. I looked under pointing devices (mouse) in control panel but don't see where to do that. Please instruct--and nice to meet you Dan--or maybe I already know you-LOL!
 

Bob time to start a consultancy business..

do you have any tempo changes in the project?

if so they may affect the length of Strings Samples playback if the Automation nodes collide with the point when Tempo changes. 

So, I am at 256 right now. Should I have to move it up to 512 or 1024? It's after the 40 tracks are done, synth programs open, waves plugs on most busses or individual instruments

 
Hell YEA!! Raise it to 512 or 7?? or 1024. do this before doing anything else as this will most likely fix it

What OS are you on and what version of Sonar? 

I am hoping it is now in my signature.

Are you using X3E? There is some fairly costly stuff that takes place when hit testing the mouse in the clips view area. Try and find out if it happens when moving over a specific track or not. That might help narrow the cause. Also make sure you have the multi processing engine enabled.
If its glitching it would imply that your CPU can't keep up with the load of the UI hit testing at low latency and this is causing the audio to glitch. Raising your latency should help with this.
You can post a screenshot of your clips view area so we can see whats present on screen.

Putting it at 1024 I am totally smooth to do everything. Hmm. Should have done that first---decided to drop the strings anyone--leave it a combo.
 
Thanks everyone for the help.
 
 
I would be solved in my original thread title but forgot how to do that 2. Not so use to this format (forum). Been away for awhile.

Nice to hear from you - been a long while.

UPDATE--after editing, adding envelopes, fades, nodes, tweaking plug-in's --if--after pushing play, if I move the mouse around in the clips area or in the the area to the left that holds all your busses/tracks/plug-in names (what's that called? I've only been using Cakewalk since Cakewalk 3 --you'd think I would know) I digress--SO, if I put the mouse back in the toolbar and click before hitting play, then it doesn't do it-stable as my Golden Retriever's love. I can live with that. I do have to face the problem of adding strings now. With all the wav plug-ins in I get terrible latency. Can you fix that? No stutter, just a delay. Probably using about 20 of them. I guess I'll export the mix and bring it in as a stereo wav, bypass the plug-ins, record the strings, delete the mix, enable the plug-ins and do the final.  (or push PDC or bypass the plug-ins and play to a lopsided mix).Would love for you to hear the song.

bumped up to 1024 and smooth.

If it is fine at higher latency it means that hit testing the clips view area is putting too much load on one of your cores that is used by the UI. Since that same core is in use by the audio engine its probably overloading at low latency and causing glitches. At higher latency the load is lower and so it doesn't overload. Bottom line is an excess load on even one core can upset the load balancing and cause glitches when you are running at super low latency. While editing its normally recommended to not run at low latency for these reasons. A moderate latency like 1024 samples should be fine.
 
That said if you can make your project available somewhere to download we can take a look and see if there is something that can be optimized better to alleviate such glitches.
 
Regarding the latency with plugins there is nothing we can do to prevent it. If plugins have delay, SONAR's PDC needs to delay other tracks to keep your audio in sync so its normal. Don't track with such plugins active as far as possible.
