Playing back a screen capture video with narration is buffering

Problem: When trying to edit a video with narration in the ActivePresenter edit window, I’m experiencing a lot of pausing and buffering as the playhead moves forward, particularly on my audio. This is making it extremely hard to correctly edit the content at a detailed level.

There’s a noticeable delay from clicking ‘play’ to when the playhead moves, then the audio content starts to pause and stop/start when I’m trying to replay it. This inevitably leads to dialogue errors in the final output.
