Soo…. you got your cool new widescreen lcd monitor and all is great in your world until you find out that one or more of your favoirite games does not support the 16.10 aspect ratio and looks bad. Well It may be possible to play some of your older games on your new widescreen monitor with the help of the folks at the WSGFWiki.
My test was “Duke Nukem: Manhattan Project” a game that nativly supports up to 1024×768 in the gui but fully works at 1440×900 via a ini mod.
