Until the next version when widescreen resolutions will be options in the menu, (that will be great Tequila! - heaps of resos there to choose from - hope you can also put aspect ratio next to them to make choosing easier - like 16:10 or 16:9). Currently to make SG run in widescreen you have to do some customizing using configuraton files or the console.
The easiest way is to make a custom configuration file (autoexec.cfg) that will run every time you start the game.
1.) browse the smokinguns folder.
2.) Make a new text file, save it as autoexec.cfg.
3.) In that text file copy the three lines below, (change xxx's to whichever resolution you require. width is the larger figure)
4.) save the file and run the game as usual. Enjoy widescreen and greater immersion in the game.
seta r_customheight "xxx"
seta r_customwidth "xxx"
seta r_mode "-1"
ChainLightnin' - With your high resolution monitor, you'd need a super computer to run at that resolution. You could try one of the lower modes. So long as it's the same aspect ratio it will look good. Also 16:10 are 1280 x 800, 1440 x 900, 1680 x 1050, 1920 x 1200 and 2560 x 1600.
To see the max your video card will support, right click on your desktop / settings / screen resolution.
In case there's other games you have that don't support widescreen straight off, this site has heaps of info
http://www.widescreengamingforum.com/fo ... php?t=4066 (quake 3 page) It's kind of relevant as SG is based on Quake 3, except the q3config is in the smokinguns folder (and won't work for 1.1).
AND FOV (field of view) definitely doesn't work in SG. I've tried it through autoexec.cfg and compared screenshots. It's cheat protected for sure.
