Hi everyone. I need OBS to run using just 4 CPU cores for streaming, not all available cores. That way the game can still run smoothly on the remaining 8 cores. When I open the settings, I see a list from 0-23, which I think includes both physical cores and threads. I’m using a Ryzen processor and want to know which ones are actual cores versus threads.

You're only viewing individual threads, not the main components. Your processor is running SMT, simultaneous multi-threading. This setup means each core behaves like two threads at once. It doesn't imply a dual-core and single-thread scenario. You may be looking for the boundary where one CCX starts and another ends.
