AMD Ryzen 7 and threading question.

So, I play Mount & Blade: Warband, which is an older game.  There is an option for "Force Single Threading," which I always pick because of threading issues with new CPUs on an older game.  This PC is new, and I was told that the latest CPUs don't have threading issues with older games like before.  Is this true?  Should I disable "Force Single Threading" or just keep it enabled in regards to my CPU?
