When it launched with that tag line both Intel and AMD were promising 10GHz single core processors within the next 3-5 years and obviously that never happened. They both ran into issues trying to get processors up to those speeds and opted to go multi-core to achieve performance boosts. EQ2 was written to run on a single core machine and to use every bit of processing power that core would give it. Converting from a single core/single threaded app to multi-core/multi-threaded is what programmers call a "non-trivial" task - which is usually shorthand for you'd be better off scrapping it and starting over. I've logged into the beta server a couple of times since these changes were pushed there and I've seen some improvement in my FPS using my current settings. I was even able to boost my settings up a notch from a customized version of balanced to whatever is above that. I still went in and turned off some of the shadows and all of the flora stuff but that was mostly because those things bug me not because they were bogging me down. Still, as just a rough guess I'd say it's about a 5-10% boost. Nothing earth shattering but every little bit helps.
