Hi there,

I would love to optimize my old OpenGL games to get the most out of the individual game.
I really don't like the "smoothness" the standard settings give most old games, software-mode
looks mostly better but then thing like the sky are not smooth scrolling anymore, so it has to
be a combination of both)

So I checked my hardware (i815 solano with i752 gfx-chip) and this thing is capable of
anisotropic filtering. So I made some tests but I can't activate the anisotropic filtering.

What is the correct way to turn on anisotropic filtering via autoexec.cfg
(HL1, Gunman, Q1, Q2,)

I am using only GL_LINEAR so the near objects are filtered, but the things that are farer away are not smoothed out completely.

anisotropic filtering isn't a standard texture mode and is a technology that came standard years after Q2/HL and so would need to have explicit support in the code, otherwise you'll have to override it in with your graphics drivers (that's why it's there for nvidia, as they've proposed EXT_texture_filter_anisotropic in 1999). The earliest aniso GL implementation I can think of in a released commercial game was in Star Trek Voyager Elite Force.

(also as it's id tech, be prepared for crap advice, like about picmip, disabling lightmaps, jpeg'd and back snake oil, incompatible source ports, etc)
