1: I think there are keyboard controls (try arrow keys, numpad, wsad) but I just hold down the middle mouse button/mouse wheel and drag the mouse.

2: Probably a memory leak, immediately after it crashes post you debug.err from the elemental folder in my games in my documents in the support forum and it will probably be fixed with a patch very soon. Meanwhile try fiddling with the graphic settings. There are issues with certain anti aliasing modes in the ATI control panel for instance (Adaptive sampling specifically I think).

3: Where do you live, I live in Australia and I probably wont see my box for week a two.

1.  Click and hold middle mouse button and rotate moving mouse.  I despise this and despise not being able to remap it.  I have strong, STRONG hands and it's rare to have a mouse with a clickable middle mouse button that you can use with any degree of control and without developing carpal.  You can also use CTRL+arrow keys but it's slower and maddening in other ways.  Customizeable key bindings, please, like most retail priced high quality games have!

2.  ATI issues and game sluggishness are known issues and high on their priority list (sluggishness at least).  I stlll have issues like not being able to alt+tab with GC2 even after two expansions and countless patches.  For whatever reason, Stardock, unlike every other developer on the planet, seems to do something that never works correctly with ATI cards.  Dunno if it's DirectX usage, rendering technique, how they do their game loop - but something just isn't right.
