I think everybody should take a deep breath and relax. This is a sim after all. Even if they're not perfect, they're still wonderful additions to an already fantastic sim.
Edit: And to expand on that, compromises have to be made. We're all not running the same hardware. Some of us might even be using a full 3 axis simulator, while others are running off 5 year old laptops, and everybody in between. Plus, how does this not look freaking cool. You can almost feel the speed just by looking at this.
