I've just installed Beta 12, which seems to load my Beta 11 save, and is instantly less choppy than before. (To be fair, I didn't install the Blue Marble option, despite loving their graphics.) It's still a bit choppy when scrolling across the map with the scoreboard extended, but the animations don't stutter and it's a lot better than before.
As you know, Choose Religions is completely inoperable and, for some reason, the Financial Instability bug is back, when I have over 1000 gold in the Classical era and making +9 a turn. Also, the mouse-over text has disappeared from the Revolution bar in the Cityscreen. I can now only see what's affecting my cities in the Revolutions dialogue box (Ctrl-Shft-G).
