			Restricting to PCX textures can go a long way for storage and loading times (crushed PNGs are loading torture) and Pi doesn't look like a device that would support S3TC anyway. I believe even Darkplaces supports PCX files.
and I don't mean for paletted texture support, but loading indexed data and 24/32'ing them could help loading.  This is a slow processor and 6thgen console-esque compromises should be taken in mind for it.   Don't expect Xonotic working overnight , it can barely handle Q3A.
