Prior to today, I had zero issues with recording/mixing/playback, but I still decided to click the box regarding "enable multi-processing". Today, nothing will play without constant glitching. The box stating "enable multi-processing" is no longer there. It has disappeared completely. I thought perhaps changing buffer/rate/etc would bring this back, but it does not. I've changed those settings so many times now that I cannot remember their defaults. Lesson learned.
I just want to get the settings back to how they were prior to changing anything, it all ran very smoothly without issues or performance problems.
In the attached picture, you can see there is no longer "enable multi-processing", and clicking on the "Performance" tab does not show it either.
