[2021] Performance Issues? Try this

Yeah, known fix for horrible performance on the older AMD chipsets that can't handle multithreading properly. May have a similar effect on 10th and 11th gen Intel chipsets for similar reasons. Locking it down to 2-4 physical cores is beneficial on those chipsets because the architecture doesn't support proper multithreading.

If you have a Gen 3 or Gen 4 Ryzen, Or a gen 3, 4, 5, 7, 8, 9 Intel, this isn't an issue.
