There is nothing on your end that you can do to adjust your experience. The game itself throttles the video and graphic capabilities of each system running the game.

The only thing you can do is wait til Bio decides to port the game over to a proprietary engine. The one they use now utilizes a single-core, even if you have and are optimized for 8. Instead of building up there own in-house graphics engine, they leased one from another company. And apparently that company isn't providing support to Bio, due to legal concerns Bio would use that against them eventually.
