As far as i know, FXT1 a texture compression from 3DFX was invented to have a patent free alternative to S3TC. But the Wikipedia article claims, that some parts of FXT1 might infringe the S3TC patent. But this isn't the only problem, the main problem is that it is marginally supported by 3d drivers. Which results in the problem that it is practically not usable. But there is an OpenGL Extension for it. See: http://en.wikipedia.org/wiki/FXT1 and http://www.opengl.org/registry/specs/3DFX/texture_compression_FXT1.txt But i want to ask. What hinders us to ship all FlightGear textures as compressed *.dds Files and provide a software tool to uncompress them before FlightGear is launched for users, that don't have a videocard with 3d drivers that support S3TC? Then flightgear should be able to select the appropriate texture files on the fly.
