It seems that the PC version of Tom Clancy's Ghost Recon: Future Soldier, which was just released yesterday in North America along with a 385MB day one patch, is a buggy mess even after the patch is applied. Users have been glomming the official forum bug report thread non-stop since its release.
Complaints include the game not recognizing the mouse, the game resolution being stuck at 720p or worse, framerate issues, key bindings not saving or being out of whack, sound issues, online dropouts, and general accusations of the game being a console port.
Moderator Ubi_Antoine reassured in the thread that "the team continues to work hard, improving the game experience, supporting the title and listening to the feedback. There are multiple updates planned over the life of the game."
Future Soldier is due to be released for PC worldwide on the 29th June. Caveat emptor.
