* **vid_gamma**: The value used for gamma correction. Higher values look
brighter. The OpenGL 1.4 and software renderers use "Hardware Gamma",
setting the Gamma of the whole screen to this value in realtime
(except on MacOS where it's applied to textures on load and thus needs
a `vid_restart` after changing). The OpenGL 3.2 and Vulkan renderers
apply this to the window in realtime via shaders (on all platforms).

brighter. The OpenGL 3.2 OpenGL ES3 and Vulkan renderers apply this to
the window in realtime via shaders (on all platforms). When the game
is build against SDL2, the OpenGL 1.4 renderer uses "hardware gamma"
when available, increasing the brightness of the whole screen. On
MacOS the gamma is applied only at renderer start, so a `vid_restart`
is required. When the game is build against SDL3, the OpenGL 1.4
renderer doesn't support gamma. Have a look at `gl1_overbrightbits`
instead. This is also set by the brightness slider in the video menu.
* **vid_fullscreen**: Sets the fullscreen mode. When set to `0` (the
default) the game runs in window mode. When set to `1` the games
