Crysis Remastered has received its first PC patch, adding additional options to the game, addressing the stuttering that's caused by the game's Ray Tracing options and fixing a large number of minor bugs within the game. 

For starters, Crysis Remastered now features lean options, a feature which was present within the original PC release of Crysis. This change brings Crysis Remastered closer to its PC original. Beyond that, Classic Nanosuit controls can now be used with controllers, and shortcuts have been added to make suit power switching faster. 

A large number of bugs within the game have also been addressed, such as the game's missing textures when using the game's low texture settings and a bug which caused the game's HDR mode to appear too bright in some cases.
