While i'm not completey sure this is my computer or OBS, whenever I record my Minecraft Videos (harharhar idc) the game itself doesn't lag. When I stop the recording and go on to look at the video file I transfers over to MP4 (easier for iMovie) the video file seems to lag out a ton. After about 3 seconds in the video it just freezes and this used to not happen as much as it did now.
