| | 1 | 0 A.D. uses the standard [http://en.wikipedia.org/wiki/S3_Texture_Compression S3TC] texture compression format, which saves at least 75% of video memory usage, improving the game's performance. Unfortunately S3TC is [http://dri.freedesktop.org/wiki/S3TC not supported by default in Mesa] (which provides OpenGL support on Linux) due to uncertainties over patents. |

| | 3 | The game will automatically enable the `force_s3tc_enable` DRI configuration option, which helps when using drivers that support texture decompression but not run-time compression. (This can be disabled via the game's configuration file: see `force_s3tc_enable` in `data/config/default.cfg` in the install directory.) |
