    Does the nvidia geforce 580m support dx11 tessellation? Is this something that can be enabled in games that support it (like ambient occlusion) or is it an automatic setting for dx11?

    Tessellation is supported by all DX11 compatible cards, AMD or Nvidia.

    So yes, 580m does support it. Generally it is an option on DX11 games. AMD give control over Tessellation settings on the Catalyst Control Center. I don't know about nvidia cards.

    What kind of performance hit is there when you use it?

    Performance depends on how the game use tesselation.
    I tried it in Batman: Arkham City and the game would slow down, when it was already cut in half by enabling Dx11.

    yes 580m is dx11 ready. you can manually activate ambient occlusion via nvidia control panel, then manage 3d settings, then global settings, the very first option is ambient occlusion. otherwise some games utilize an 'in game' settings like bfbc2 and bf3 (HBAO), brink (A.O. enabled) etc. Bartman Arkham city so far has the bugged dx11 option as far as i know.

    performance hit? it really depends on how the game optimizes the tessellation, some games use it well with a minimal impact on frame rates, some are taxing.

    Crysis 2 is a great example of horrible tessellation.

    The 580M has the same tesselation of a lower clocked 560ti desktop (they are the same chip and have 8 polymorph engines).

    With Nvidia each shader cluster has a polymorph engine unlike AMD's fixed function unit that is in every chip.

    580 Desktop = 16
    580M = 8
    570M = 7
    560M = 4
    555M = 3 (144 shader)
    550M = 2 (96 shader)
    540M = 2
    520M = 1

    batman's dx11 was fixed thankgoodness. now i can play the game "the way it was meant to be played"... on an ATI muhahahaha

    tessellation and advanced dx11 features such as ambient occulsion tend to dish out quite a performance hit in general. but it makes things look so pretty (especially ambient occulsion, tessellation is much more subtle)
