My Vegas preview slows down and stop responding when I am editing videos with gameplay and commentary is separate tracks. It slows down when I am clicking around and cutting clips as normal, and if I go too fast it will crash. The preview also has a slight delay when I try to playback. I know my computer is good enough and I have recently updated everything and removed all corrupted files from it. If it helps I use "OBS" software to record and Vegas pro 16.0 to edit.
This DOESN'T happen when I record gameplay without commentary and its just and mp4 file. (I also have two-track recording that separates my microphone and gameplay audio, and that is when the glitching happens.)
