Sudden CPU overload

[David_Greenwood]

Hi,

I have this weird problem with my Pro Tools 9.

I load a project, I have a fair amount of tracks but nothing to radical and a fair amount of plug-ins but still nothing to radical. After 20 minutes I get this message a-la "CPU overload, increase buffer size or remove some plug-ins"

I had buffer on maximal and as I checked my CPU usage in Pro Tools its around 20% all though system CPU is less.
So I tested it. I loaded a fair amount of tracks and put it on loop, around 40 minutes nothing happened and the CPU was around 2%, added 4 common and not that power hungry plug-ins on every track and looped it again (CPU was at this point around 20%). About 20 minutes later I got this message again and like always it worked slow afterwards. But the CPU levels in Pro Tools were still around 20% so it seem that it has a sudden increase of CPU at times.

Here is what I did to try to resolve the issue:

- double checked the buffer size and it is at maximum
- Checked that my playback engine was NOT on Pro Tools Aggregate output but on Built-in output
- Checked my Audio Midi options on System and it was set to BI output
- updated the system


The amount of tracks and plug-ins worked fin in PT8 but its horrific in PT9 all though the CPU is around 20% which is not that much.

So, what should I do to resolve this sudden increase of CPU in PT9 so I can work normally.

Hope you guys can help.
Cheers!

I think we can help after you give us some info. Like your OS version, PT version, computer CPU, drives attached, memory, stuff like that.

Have you checked to make sure all plug-ins are current?

What troubleshooting have you already done as listed on:

Same thing just happened to me.. I can't even pass signal anymore. Been meaning to switch back to from leopard to lion anyway, now that PT is supported by Lion. Ill see if this helps any.. Good luck, let me know if you get anywhere, I've been at a stand still for about 45 minutes now, tried everything I could think of.

Upon switching switching to Lion I didn't have that error anymore. Although I did come into contact with the pause play glitch.. Not quite sure how it got initiated, but after a bit of a search, I found that it was Task Manger > Drop Down Menu on the right > Pause During playback... Why that option is even there? I'm sure Ill Laugh when I end up figuring it out.
