Basically every other "core" in an fx processor is just an integer unit. It doesn't have an FPU unit which MWO heavily uses. Any FPU calculations executed on the second core likely take longer because they have to be resent to the first core to be handled. You can use task manager and set affinity to every other core, 0,2,4,6. Other issues have to deal with scaleform and I have been working on some tweaks to deal with that. This is what I managed to do to my user.cfg
