The resolution list is pre-determined. Supported resolutions are 640x480, 800x600, 960x600, 1024x768, 1152x768, 1152x864, 1280x720, 1280x768, 1280x800, 1280x854, 1280x960, 1280x1024, 1360x768, 1366x768, 1440x1050, 1440x900, 1600x900, 1600x1024, 1600x1200, 1680x1050, 1920x1080, 1920x1200, 2048x1536, 2560x1600, 3840x2400, 3x1024x768, 3x1440x900, 3x1680x1050.
Some resolutions listed in-game but not in the autoconfig tool. Resolutions can also be set in options.ini in the installation folder, but resolutions not on this list will be rejected (the game will fall back to another resolution).
Menus and FMVs always run at 800x600 instead of the chosen resolution.
Reading a post over at Rock Paper Shotgun, I found out that Studio Mektek has released a free version of Mechwarrior 4. http://www.mektek.net/projects/mw4/ This was done fully in conjunction with Microsoft and Smith & Tinker.
Free Mechwarrior game, built with modern tech? Sign me up. In the mean time, who wants to check out the WS and TH/EF support?
Somebody posted the files in Megaupload and Filefront. You can find them in the last post of this thread: http://www.mektek.net/forums/index.php?showtopic=156386
I've got it working in 1920x1200 on my system. What I did was download and install the MTX installer. Run the installer and set the default game location. The MTX application takes forever to run, and crashes a lot. Be patient. Rather than using MTX for the downlaod, I just grabbed them via torrent (3 files: The main game, plus two updates). I ran the MTX utility and did File | Open .mtx file and pointed it to the main file. It will verify the checksum, then install the game. I then did the same thing with both of the updates. Once the updates were installed, it worked fine in WS.
Some people were having trouble with the game. It is suggested that after doing the base install, you run the game. If it works and you get to the "create account" screen (or whatever it's called), exit. If it doesn't work, create a shortcut to the executable. Add "/gosnovideo" to the end of the launch link in the shortcut and try that. Then install the updates via the MTX app. BTW, that option turns off the intro videos.
