The downside is that the upgrades naturally come with an increase in Crysis 2's system requirements. Collectively, these work to add a fourth preset to Crysis 2's graphical options - 'Ultra'. One will add DirectX 11 features, such as DX11 Tessellation and Displacement Mapping, while the other upgrades Crysis 2 with high resolution textures (HRT). The next two files can be added in any order.
The patch also updates the anti-cheat systems and fixes gameplay bugs, such as an error which removed bullet penetration from previous versions of the game. Even without these later improvements, Version 1.9 adds Realtime Local Reflections and Tone Mapping, improved graphics menu options and support for multi-GPU systems. The first file you need to download and apply is a standard patch for Crysis 2, bringing the game up to Version 1.9 and providing computability for the later enhancements.
