The aim of this mod is get the best out of the graphics of this classic game, but make it as natural as possible. This means overprocessed shaders won't be added. The mod contains all of the best available textures and a unique System.cfg, optimized for 2,5K and 4K downsampling. The mod also contains a tweak guide and adds hotkeys to the nanosuit functions. You need to have a 64-bit system and a good graphics card to run it. Please make sure to follow the installation instruction that comes with the mod.
I don't know that there are sharks in crysis long time, but I've meet it in Quality Mod last time.
It serves as a border guard, it doesn't let you go off the map XD
