weird bump mapping effect

this is rather strange...and i think it is to dO with my graphics card...
..everytime i switch on bump mapping( speeds up my frame rate by 2-3 frames).... when the car hits 80mph or so the road from the horizon goes black while the foreground is normal... if only i can show you a picture but it won't copy and paste from gpx patch.

i tried downloading a bump mapping which in the other hand fixed it "ok" but it still had a little trace of that black in the horizon... when i turn it off the roads looks unko and untidy with road lines here and there...

i running a win2000 pentium 4 1.7ghz ati radeon 7000/ VE 64mb with openGL and Direct3d support...

F9 in gpx_patch will take a screenshot I think try it, the screenie should appear in the screenshots dir, subdir of gpxdata dir ok. as for your problem, I think your card cannot render bump mapping, that's a guess.

probably....

There is a blur effect on the bumpmap.
It is 'stretched' in proportion to your speed.
Also the mipmap bias is adjusted.

It sounds like your card and/or drivers aren't handling the bias very well.
Probably sampling 'of the end' of the mipmap chain.

I suggest you might want to try newest drivers if you haven't.

If this doesn't work then its probably some hardware limitation with the ati 7000.

Hello,

Hey RazTahZ..I have the same problem with the bumpmapping too. I'm running a Radeon 7500 in my machine. I would love to be able to use bumpmapping, but something is wrong with the ATI drivers...or it's the ATI hardware. I've tried all the Catalyst drivers with no luck..so now I just turn bumpmapping off..

It is either the card or the drivers.I got the same thing with my 7500 but everything works right on the 8500le.
