## Graphics (OpenGL 1.4 only)
* **gl1_biglightmaps**: Enables lightmaps and scrap to use a bigger
texture size, which means fewer texture switches, improving
performance. Default is `1` (enabled). Requires a `vid_restart`.
* **gl1_intensity**: Sets the color intensity. Must be a floating point
value, at least `1.0` - default is `2.0`. Applied when textures are
loaded, so it needs a `vid_restart`.
