CPU On with Empty Rackpsace Increases Over Time


I am starting notice an increase in CPU, using an empty rackspace, over a session using GP.

Using an empty rackspace, when I start the session I think it hovers between 4% and 8%. Nice.

But, it seems (I really noticed it this morning) over time, the CPU while using an empty rackspace goes up to 20%.

This is on a new beefy Lenovo laptop. (I can get the specs, but they are good).

Any thoughts? Troubleshooting?



Global rackspace is empty?

No, there are items in the Global Rackpsace.

But, I don’t know why CPU would increase over time due to that.


What CPU usage are you talking about?
The display within Gig Performer or the Windows Task manager?

With a blank gig file?

No, I can try a blank gig file.

This is with my (big) Gig File (which uses the Global Rackpsace).

But, when I open it, it hovers between 5-8% when it is on an empty local rackspace (I know the Global Rackpsace is always active).

But, after a while using the Gig file, I think it seems to creep up to 20% on an empty local rackspace.

I am just wondering if I am missing something?

I am not having an audio issues. When I use a local rackspace with plugins, I think it goes up as high as 50% (or so?) (still no issue with artifacts, etc.)


Yes, try with a blank gig first. If the problem doesn’t happen there, then you know the issue is within that particular gig file.
On my oldest machine with a processor from 2014, a blank gig file sits between 1-2%.

If you upload the gig file, I can take a look.

Thank you. I am away from my computer.

I will check an empty gig file. I suspect a blank gig file will use little cpu and it will not change.

I will also try to see when it starts creeping up. If there is a rackspace where it goes up.

Then I can look into uploading the (big) Gig file.

Please set predictive load to 1 and test again.
I think there are some plugins in your gig which consume cpu when first used and do not free cpu when not in the active rackspace.

Thanks, I will try that too.

I spent about 20 minutes or so playing through lots of rackspaces. And it returned back to low cpu, no issues.

I will be more observant of when it seems to happen (if it happens again).


I figured I would post my follow up here.

I think the CPU on empty rackspaces went up because I left the computer a long time with a more CPU intensive rackspace open and it heated up the laptop. I had not turned on the cooling pad (I often do not). (I might have been using the laptop too).

So, I think the heat caused the CPU usage to go up. (it never caused a problem in terms of performance).

I think CPU stayed up on empty rackspaces because of the thermal issue and the fact that the cooling pad was not on. (I suspect if I left it on an empty rackspace long enough without using the laptop, it would have (very) slowly gone down on its own).

So, when I switched to an empty rackspace and turned on the cooling pad, over time the CPU came back down to 4-7 range it typically has on an empty rackspace.

That’s my theory, anyway.
