This issue has been boggling my mind for quite a bit of time, and it's gone on enough for me to finally post a thread to try to figure it out. When I hit F1 (my hotkey to start recording), OBS goes into a "Not Responding" state for a few moments, then starts recording. However, then, my recording freezes (experiences encoding lag) for about 10 seconds. After this, no other major lag issues occur.
