    I've been playing Quake and since people kept saying that it looked better without texture filtering, I decided to deactivate it.

     

    Everything looks much more crisp! It's been so long since I played the original game (i.e. without filtering) that I just forgot how good it looked in comparison.

      @Albertoni AFAIK nearest is pixelated and linear adds filtering. Also, the GL_NEAREST_MIPMAP_LINEAR mode supposedly makes texures look better at distance, but the anisotropic filtering does a better job at that.

      I use both MIPMAP_LINEAR and anisotropic set to 8x.

      GL_NEAREST_MIPMAP_LINEAR will use nearest neighbor filtering (hence it'll look pixelated), but interpolates between mipmap levels, giving better quality to textures that are further off.

      GL_NEAREST_MIPMAP_NEAREST would be the equivalent of software mode Quake, iirc.  And GL_LINEAR_MIPMAP_NEAREST would be essentially bilinear filtering, while GL_LINEAR_MIPMAP_LINEAR would essentially be trilinear filtering.

       

      Anisotropic filtering basically does some extra work with the mipmaps makes textures that are viewed at sharp angles look a lot better.
