Are there any ways to optimize performance in CS6?

[MikeHarrison]

Over 90% of my work involves recording and editing mono files. Having used Audition CC for a year, I've now gone back to CS6. The plugins I use are generally only EQ and dynamics, and no plugins are ever "live" during recording or editing. My I/O buffer is set at a good balance between record and playback performance, 512 samples.

What I'm noticing is what seems to be a bit of sluggishness when scrubbing; dragging the cursor through the audio. I've looked around to see what settings I can change in hopes of improving this, but I've run out of ideas.

Can anyone offer any suggestions, please?

Thanks.

Often this ultimately depends upon the sound device you use. A decent external one with an ASIO driver usually performs better than an internal one using a Windows driver, especially if it's resampling your audio (often without your direct knowledge...)

Thanks, Steve. I'm on a Mac (running OS 10.12.6; Sierra), which uses Core Audio, with a FocusRite Scarlett 2i2 interface. Both the Scarlett and Audition are set for 48k.

Well, if you're on a Mac, then I'm afraid I have no idea what else you can try - most of us simply don't use them. If you're dead lucky, one of the devs will see this, and they should have a better idea as to what you could try. What doesn't change though is that if this is only happening intermittently, then something in your machine is taking over resources that Audition would otherwise be using, and you'll need somehow to find out what that is.
