    You never asked a proper question in the English language.

    You just (tried) to state that you have a white progress bar at the bottom of your screen at some times, and at other times you do not. There was no actual question present in your first post.

    Questions can take the shape of: "<Verb> <subject> <more words> <object> ?"

    So, do you want to get rid of the progress bar? Do you want to keep it? Or would you just like to know why it occurs in some cases and when it fails to occur in others? <!--emo&:)--><img src='http://www.unknownworlds.com/forums/html//emoticons/smile-fix.gif' border='0' style='vertical-align:middle' alt='smile-fix.gif' /><!--endemo-->

    what do you mean by "progress lines", I've never heard that terminology in the terms of anisotropic filtering? Do you mean faint horizontal lines two-dimensionally on the screen all the time? Or moire patterns?

    Because AF (anisotropic filtering) is not responsible for what you describe as "progress lines".
    I assume you mean the kind of texture "break" that can be seen best on floor gratings, from where the floor-texture becomes more blurry in the distant ?

    These lines are the point the renderer switches to the next texture mip-map (which is a smaller, thus more blurry, version of the same texture), either directly from one mip map to the next smaller one (this is the case with just bilinear filtering, and you will see the "lines") or by interpolating between the two texture mip-maps (often referred to as trilinear filtering).

    Anisotropic filtering o.t.o.h. is used to "sharpen" textures with flat angles (in relation to the view, like floors or side walls) where some texture features become all too blurred in the distant (again best noticable with grid/grating textures).

    In HL (won/steam, dunno about source?), you control the mip-map interpolation with gl_texturemode, i.e.
    <b>gl_texturemode gl_linear_mipmap_linear</b> will enable interpolation (linear, smooth) and
    <b>gl_texturemode gl_linear_mipmap_nearest</b> will disable it (nearest mipmap chosen, see the lines?)

    In your case, it's probably just those settings...

    alright, with gl_linear_mipmap_linear all bad "progress lines" are gone and smoothish :]
