I'm trying to stream an older game (Prince of Persia: Warrior Within) that requires single core processing to reduce bugs (jump and speed glitches) but this causes the video stream to lag. The game plays fine while streaming, no lag outside of normal graphics issues. I have an i7-6700K quad-core processor, 8 threads, and another thread suggested setting CPU affinity for OBS to use all the cores except the first core being used by the game but it still causes the same stream lag issue. I've also tried changing the OBS CPU affinity to as many other combinations of the cores I can think of. The same issue occurs when trying to record to my computer instead of stream. There is no stream issue when the game and OBS are set to use all 4 cores, this just causes the gameplay glitches. Any suggestions?
