I can imagine that this helps you to manage multiple instances of Ryzom, But Ryzom is still a single-thread program. There is no known method to spread only one instance over multiple cores. I don't have problems with processor affinity in general, I'm also running Ryzom only once at a time.
I would expect more popularity, that you have to pay for it, or that it is an essential part of Windows already since it would fix lots of problems with other single-thread software. My guess would also be that it needs to process an exe-file before usage, since great changes to the code has to be done in order to make it work.
Before I try that - can you confirm that bill2's processor manager is the almost impossible exclusion to that rule?
