Hello, I am trying to run DD but every time I try to record, OBS can barely get 15 seconds of footage. and said 15 seconds are only 3 frames. how can I optimize OBS to properly record my DD runs?

I am unfortunatly not really able to give you an answer with these little details. One thing you could try is making a backup of your OBS settings and performing a factory reset to see if that helps. You may also need to look into your specs to see if recording is viable; DD is not a light game to run, as far as I know. If these don't work try lowering the graphic settings in DD and lowering the video quality in OBS. Asking around in the discord might also help. I am there rarely however.
