I'll go ahead and answer that question...no. But "perfectly fine" at this point means that 1) it doesn't crash on test scene and 2) you can move (even if very slowly). We really can't be making assumptions about final performance at this point. The betas are not meant to be indicative of the final product - they are meant to give us something to get excited about while also being a part of the development by posting bugs, providing performance stats, etc.
The only way to see 60 FPS even on a top-notch graphics machine is to either put almost nothing in the level or to stare blankly at the sky.
