I wondered whether anyone else is experiencing the same thing I am; some of
the track graphics in F12001 'shimmer'. I can not think of any better way of
describing it than this. I have
a) tried different refresh rates for my Llayami 21' monitor (have upto date
drivers, not the generic Windows ones)
b) a variety of graphics cards drivers (Geforce 2 Ultra 64mb) from 6.50
right upto 23.11 (use 1024 res at 16 bit colour, but higher res also have
similar 'shimmering' problem)
c) played around with GeforceTweak
d) tried different graphics settings within game, although with my rig I
wouldn't of thought that the machine would be having a problem; Athlon 1.4,
256mb ram, Geforce 2 Ultra, SB Live, Act Labs Wheel/pedals (force feedback
not activated)
As an aside, when I click on icons within the game, the icon sound has a
long reverberation sound to it. Is this normal?
Any advice appreciated, as games like GPL and Nascar 4 work so well on my
computer, and I'd love F12001 to the same.
Thanks

I have that too, on a GF3 video card. Oh well, back to GPL...
Bye,

The 'shimmer' is due to some Z buffer issues that are really only resolved
by moving to 32 bit. and this will impact the framerates quite badly, you
GF3 guys should be ok though.

with F12001, but it doesn't make the tracks shimmer, it makes distant

over the outside.
The shimmering is because ISI have played around with the mip-map LOD bias
setting in D3D to get a sharper image. This is probably in response to the
criticism F1 2000 got over it's 'blurry' tracks. Anyway, ISI have changed
the LOD bias which changes the distances at which D3D switches to the
smaller textures. Each of these distance have been moved closer to the
screen, so the game is using textures that are too big for the particular
distance, hence you get a shimmer around mip-map boundaries.
If ISI had programmed support for Anisotropic filtering, it wouldn't have
been necessary for them to manipulate the LOD bias this way. Also if they
had programmed support for W-Buffering, the 16-bit z-buffer problem would
not be there.
You could use RivaTuner to put the LOD bias back the other way, then force
anisotropic filtering on, and that should remove the problem.
Personally, once I'm into a race I hardly notice the shimmer.

Ya can't help but loving a post like this.

like billboards or fences would come into view as if blocked by a moving
train. You'd see the billboard flashing with short breaks of the actual
image between blurred blocks until you got close enough to see the full
image. I figured it was a 3dfx issue and since it didn't impact the
framerate or the actual track, I never worried about it.

Now *that* is a Z-Buffer issue. The sparkling or shimmering textures is from
a lack of mip mapping or anistropic filtering.

I don't see that in F12001.
