This new patch should include better dynamic texture support while running in enthusiast mode. The TimeDemo can now be started from the command line. But the biggest one for many is they have finally fixed the issue in Vista where the game will launch in windowed mode if you are not running at your monitor's native resolution (which is most people) as well as the Mouse offset problem that pops up so often.
The new patch will also bring the long awaited 64-bit mode to the game. Unfortunately 32 and 64-bit saved games are not compatible with each other.

As far as new features are concerned, we know of one that has been long awaited by gamers and enthusiasts alike, and with a warm welcome of our appreciation is it finally here: 64-bit mode. CryTek added 64-bit executables for Windows XP x64 and Windows Vista x64, however we're sure that the Vista executable will also work with Windows 7 x64 beta. In Windows XP x64, a new shortcut will be placed under the Crysis Warhead program group. In Windows Vista, users can right-click the Crysis Warhead icon in Game Explorer and choose to run the game in 64-bit mode.
On another note, there is only one known issue with the patch. Games saved in 32-bit won't work properly when running the 64-bit version and vice-versa. Yet, the fun with improvement patches like these is that the game is always re-playable to say the least.
These are the full patch notes as seen in the readme file with the patch. After applying it, the version displayed in the lower right corner of the game menu is 1.1.1.710. There is still no set release date for this first patch, but we will definitely stay informed with any announcements made.
