For info on how to permanently change various game settings, see the file [source:/ps/trunk/binaries/data/config/default.cfg binaries\data\config\default.cfg] (can be found in the folder where 0 A.D. is installed, which varies on different operating systems). To change a setting, create a '''new''' local settings file. The path varies by your OS, see GameDataPaths. Open the new file in your text editor of choice, and copy any lines you want to change from `default.cfg` into the new `local.cfg`.

== Graphics Settings ==
To switch between Windowed and Fullscreen mode in-game press '''Alt'''+'''Enter''' (except OS X, see below). There are a few settings you can change via the in-game menu as well. You do that by clicking on '''Menu''', then '''Settings''', and there check/uncheck the '''Enable Water Reflections''', and '''Enable Shadows''' checkboxes. This can be helpful if the game is slow.

Here are the main graphics settings you may be interested in changing:

 * Windowed: If you want to always start the game in windowed mode instead of fullscreen or if you're using OS X (see #741 and #1593), then add `windowed=true`. You can also adjust the game window size by setting `xres` and `yres` to reasonable values.
 * Fancy water: If you have an older graphics card, or just don't want all the fancy effects, you can disable pixel-shaded water by adding `fancywater=false`.
 * Shadows: You can disable shadows by adding `shadows=false`.
 * Particles: You can disable particles by adding `particles=false`.
 * Render path: If you have any problems with graphics due to an older graphics card, add the line `renderpath=fixed` to test the game without shaders. If this fixes the problems, please [/newticket report] it as a bug to us.
 * Prefer GLSL: If you are using the shader renderpath and have a graphics card/driver with good OpenGL 2.1 support, you can enable some ''experimental'' graphics effects by setting `preferglsl=true`. These include:
   * Distance fog. Applies a subtle fog effect on distant terrain and objects. 
   * Smooth LOS. Smooths the movement of the "line of sight" (aka. "fog of war") around units. Enabled by setting `smoothlos=true`.
   * Advanced mapping effects on buildings (such as AO, parallax, normal and specular mapping). First you need to set `gentangents=true`, and then depending on your hardware, you can set `materialmgr.quality=10` to enable all the effects, `5` to enable only some of the effects, or `0` to turn them off.
   * Postprocessing. Enables additional effects, such as brightness/contrast control, depth-of-field, LDR bloom, etc. Set `postproc=true`.

You can also set the game to run in windowed mode in a `local.cfg`, please see the `default.cfg` for info on how to do it.

== Sound Settings ==
To change whether or not music plays in game bring up the in-game menu by clicking on '''Menu''', then '''Settings''', and there check/uncheck the '''Enable Music''' checkbox.

== Keyboard Shortcuts ==
The keyboard shortcuts can be changed with the same process outlined above, just copy the relevant line from the `default.cfg` file to the `local.cfg` and change the part after the equal sign ('''=''') and before the semicolon (''';'''). For shortcut key combinations edit the keys between the quotation marks ('''""'''), and use a plus sign ('''+''') to tie together more than one key (so don't remove it unless you change a multi-key shortcut to a single key shortcut).
