HDX CPU Spikes
 

Hello all,
Since switching from an HD Native system to HDX, I’ve noticed significantly more CPU spikes when bouncing a mix. This doesn’t make a lot of sense as my System Usage shows a finished mix usage around 20-30%. I have done the Avid recommeneded optimizations and set core affinity to reserve CPU 0 for OS processes. My DPC latency reliably tests under 200us with PT not running. Can anyone help me out with some insights or troubleshooting ideas?
Thanks!

I’ll add that this only seems to happen consistently during bounce to disk. Normal playback and mixing seems ok.

Re: HDX CPU Spikes
 

Surely you can realtime bounce if you can realtime playback without problems

Re: HDX CPU Spikes
 

This seems not to be the case. While I can play back ok, I have to freeze just about every track in the session to get it to bounce properly.

Re: HDX CPU Spikes
 

Do you have the ignore errors during playback checked in playback preferences? Untick that and you know if you can playback you can also bounce

Re: HDX CPU Spikes
 

I have tried both ways. It seems to make no difference.

It even happens when my cpu is at 5%.

Hard to guess what is the problem but you can always "print to track" id playback works and bounce fails

Have you tried deleting PT preference.
If that doesn’t help I would try to remove all the plugins from the plugin folder and intoduce back one at a time.

Thanks, Chris. I will try that and report back.
