Does it support multiple Texelfx already?
Multiple Texelfx/TMU’s can be used for single pass trilinear mipmapping for improvement image quality without performance penalty in current Linux Glide already. You will need a board with two Texelfx (that is, one of the appropriate Quantum3D Obsidian boards). The application needs to specify the use of both Texelfx accordingly, it does not happen automatically. Note that because most applications are implemented for consumer boards with a single Texelfx, they might not query the presence of a second Texelfx, and thus not use it. This is not a flaw of Glide but of the application.
