I downloaded the rygels high pack, and it runs pretty good on my pc. But I think the pack has some extra textures that ezquake does not use.

#slime
#slime_norm
#slime_gloss
#slime_luma
#slime_glow

every texture has a list like these, I am unsure of what textures the ezquake client does not use, as I'd like to delete the un-used textures.

I guess for EzQuake you can remove the *_norm, *_gloss and *_glow textures.
*_luma is used if you have gl_lumaTextures set to "1".

Cool thanks moon =). Just want to delete the ones that are not being used.
