Title. Not only has the FPS not improved, but also massive (and I mean MASSIVE) FPS drops and microfreezes have appeared, at least for me. That said, most people in the matches I've played have confirmed this on their side too. I'm getting worried about the time of the release. I'd rather play the full version later but with 60 FPS.
