To be honest, with relation to how the game looks graphically, it runs pretty aweful. But thats to be expected by a beta game made by 6 guys.
And yeh minecraft can eat ram.
Running just windows 7 and minecraft uses 2258mb ram, javaw.exe uses 1029mb of that.
I can run lower setting for not though, plus much shorter render distance....
Anyway, this is the message I get when I start the game.
" Bad video card drivers!
-----------------------
Minecraft was unable to start because it failed to find an accelerated OpenGL mode.
This can usually be fixed by updating the video card drivers.
