According to one of the people on the Halo 2 for Vista developing team, Vista is really coming along nicely. They still have some bugs, but they are being worked out very quickly, and graphical enhancements are making many of the people on the developer team call it "Halo 2.5". There have been a lot of artistic enhancements making all the characters look nice at the developers preferred resolution of 1920x1200. At that resolution, the developers can get Halo 2 for Vista running at 60 frames per second at maximum settings.Due to complaints from testers, Bungie has reconfigured the Halo 2 for Vista controls, and is working on the best way to reconfigure the mouse. The Xbox360 controller, which is compatible with Halo 2 for Vista, has received some deadzone tweaks, but anyone who uses the Xbox360 controller will definitely want to be using a mouse and keyboard. The multiplayer interface has also gotten a tweak. Text chatting and VoIP chatting is now enabled in not only the game, but in the pre-game lobby. The developer team has officially dumped all machines using Windows XP, because game's networking, video, and window-management code only work properly on Windows Vista. The XP machines were used to help code Halo 2 for Vista.
