Буквально только что соответствующий раздел был доступен, но Crytek оперативно его «прикрыла». В нем было достаточно подробно описаны все преимущества вскоре выходящего обновления для Crysis 2, озаглавленного как DirectX 11 Ultra Upgrade.

DirectX 11 Ultra Upgrade
The DX11 Ultra Upgrade is a free visual improvement add-on introducing DirectX 11 support as well as a wealth of graphical improvements and performance optimisation for both DX11 and DX9 APIs. 

When using the new ‘Ultra’ spec, DX9 platforms will benefit from realtime local reflections and contact shadows. The owners of DX11 platforms , in addition, will be able to enjoy hardware tessellation (requires the installation of the “Tessellation Package”), parallax occlusion mapping and several improvements for shadows, water, particles, depth of field and motion blur. 

DX11 Tessellation Pack (optional download)
This free pack containing pre-tessellated geometries is necessary in order to be able to enjoy hardware tessellation on DirectX 11 graphics cards. A compatible DX 11 graphics card is required. 

High Res Textures (optional download)
This high resolution textures package provides higher textures resolution for a wide variety of assets. It supports both DirectX 11 and DirectX 9 versions of Crysis 2. A 64 bit operating system and graphics card with at least 1GB of memory are required.
