Get this: When I installed OBS Studio, at first game capture wouldn't work even when I used multi-adapter compatibility. But when I tried using windowed capture, it worked like expected. Now when I went back to game capture, all of a sudden it worked too, even without multi-adapter compatibility. At this point I was very confused, but I decided to try game capture on the regular OBS, the one that didn't work before. To my surprise, even that started working, and well too. I'm not sure what happened, but after messing around with OBS studio, the options that didn't work before began working. Even the regular OBS.
