Wow, the guys are getting some crazy amounts of work in on stabilizing things. I've noticed we're already up to r1691 (when I checked it out last night, it was only r1687), and now it's playable on my laptop with draw distance down, shaders at medium, and everything else maxed. It's still lagging a little, but it's looking more like that has to do with lighting (for example, the fully-lit ACM City save lags, while Comr4de's Danube battleship isn't lagging at all for me).
