Corrupted session? DSP issue

[EdwardWilliam]

You may try these, from Frank Cook’s PT 11 310M book.

To reduce CPU processing load in a session, do any of the following:

Reduce the density of automation in places where it shows the most activity.

Turn off the displaying of Send Assignment Level Meters, Insert Gain Reduction Meters, and Track
Gain Reduction Meters (by deselecting the display option in the Metering Preferences page).

Reduce the number of instances of Native plug-ins, or convert the Native plug-ins to DSP plug-ins
(where possible).

Reduce the overall amount of Elastic Audio real~time processing by switching to rendered processing.

Increase the Cache Size setting (disk cache) in the Playback Engine dialog box.

Verify that ENABLE GPU is checked in the Operation page of the Preferences dialog box. By default,
Pro Tools' video processing is enabled on the GPU (Graphics Processing Unit). This transfers video processing to the GPU, freeing up the CPU for Pro Tools audio and MIDI. However, slower GPUs may encounter poor video playback, in which case this option can be disabled, causing the video
processing to be done on the CPU.
