Empire totalwar and running it

And performance is... disappointing. I run everything on ultra and all effects apart from depth of field switched on, and battles run at a steadyish 17 fps with full stacks, and the campaign map at a rock solid 12. To be honest, this frame rate is on the low side but the game is perfectly playable and still looks lovely. I think the problem is the programme only uses one out of the 8 cores. One of them runs at just about 100% and the other 7 sit idle. Which is annoying... On the other hand AI turns don't take as long as some others' I've read about, and I only ever get ctds from automerging units. No memory leaks or anything...
