DISCLAIMER: Much of this footage was captured on an underpowered computer displaying already-captured footage. That's a lot of capturing going on, and thus a lot of performance cost. Low framerates on Steam's in-house streaming are an issue, but everything you see in this video probably looks about 10 FPS worse than it actually is.
