r_ext[tab]
anisotropic filtering 1
max anisotropy 16
I found in the SVN these two variables: r_ext_texture_filter_anisotropic and r_ext_max_anisotropy, but it seems they are not recognized by the game ("unknown command") and will not show using r_ext[tab]; of course I can define them by using the /set command, but they will have no effect as they are not recognized.
Weird...
Edit: they can be changed via menu in tjw mod and some Risujin's mods too, but I don't notice any effect too.
