Soul Calibur V: how fix performance issues?

Basically, you don't. The game is fully playable but it's slow. It might run faster on Intel CPUs which have faster clock speeds but it won't run at 60 on a 3700x at the moment (I have one too). The game doesn't like attempts at locking the framerate at 30 either.

ah! I hope that it will be fixed in the future...
thank you for your feedback, I hoped that chaning some settings i would be able to run the game at 60fps...
