When I tried using OBS just to make a video of a game, it was laggy and had many dropped frames. It was hard to use and I couldn't figure out how to stop the lagging. Whereas, the Xbox Game bar was way simpler and the clip had no dropped frames or lag. I prefer to use Xbox Game Bar nowadays. Sometimes I go back to OBS and try it again to see it was a bug and had been patched but I had no success.
