This is just the OS scheduling CPU time, and is just smoke and mirrors for non-tech people to make them think they have more powerful systems than they actually do. "FFXIV runs just fine on my system, it barely cracks 14%" when the actuality is that that is the maximum single thread performance. Unless a program is actually coded to use multiple cores at the same time, a game without a frame limiter will max out one CPU core, always. Windows may be alternating which cores those instructions are sent to, but it's not ever going to be able to use more than one core.
The OP has a E8500, passmark score of 2291, Single thread score of 1,332
I have a i7-4770 which has a passmark score of 9993, Single thread score of 2,244 . So by comparison one core on my system = the entire power of their dual core system.
The poster above yours has a E6600 which has a passmark score of 1543, single thread score of 933. So roughly 30% less powerful than the OP's E8500. This is likely the minimum that FFXIV is going to run bearably at.
