When running at widescreen resolutions, adjusting the field of view may be necessary. First Method: While in game, push ~, which opens the developer console. Type default_fov 106.270273206 and press ↵ Enter. Second Method: Alternatively you can also open config.cfg located in <path-to-game>\Half-Life\Decay\. Add the following to the bottom of it. For 16:10: default_fov 100.39487232 For 16:9: default_fov 106.270273206 Notes If the new fov doesn't stick try creating an autoexec.cfg file in the same folder and adding the line to it.
