Uhhh good question, I was having a ton of problems with OBS and the Streamlabs version. To begin, my system wasn't even close to 75% util on anything, but I was dropping 99% of my frames. Even when recording, it would do the same thing. It would freeze and stutter badly until my GPU runs 100% for a split second and frames would stabilize. This was back with my Ryzen 5 2600 and RX 570 GPU.
