Can anyone point out what detail improves in GPL with the detail slider all
the way to the right? With my new PIII 733 + V3 3000, I can get 36fps at the
start at Spa with 19 AI opponents at 1024 with the detail slider at 2/3 over
to the right, but when the slider is all the way to the right the fps drops
to 27 for a second or so.
Now the interesting thing is, I can't see any difference in detail
between the 2 slider positions - can anyone with a better eye than me point
out what may change? One would think something must, to account for the
framerate drop.
Also, increasing the clockspeed of the V3 from 166 to 183 makes no
difference, so obviously the CPU is the limiting factor even with this much
horsepower - roll on the 1Ghz chips!
Cheers..

What changes is the detail of the cars and objects that are more
distant. The objects close to you remain detailed unless slider is moved
too far to the left. That's why you probably cannot see a difference, as
there really is not much of it anyway.

It changes the quality of details, of everything GPL draws in front of you.
With it set all the way to the left, objects are only drawn in full detail
when they are very close to you. If you whack it over to the right,
everything visible is drawn in highest possible detail, even at long
distances, which, of course puts extra strain on the graphics chip, hence a
slight loss of frame rate. You probably won't notice the extra detail at
long range unless you use a high res and have good eyesight

At least we know we are correct :).

For instance, it changes the number of polygons that form the front wheels.
When you put the slider to the left, you can see the tyres getting quite
blocky. Obviously reducing polys speeds things up.

As someone with fairly bad eyesight, I find that moving the
slider to the left more accurately simulates my myopia. Should Papy
ever implement 3Dfx-compatible anti-aliasing, then that should take
care of simulating my astigmatism too.

Now I'm depressed...

Ahhhhh good question.... I'm 18 and have fairly good eyesight and one thing
i notice in GPL is that the forward vision has never felt adequate
turning up the detail slider works to correct this a little bit by letting u
see further down the track which IMO is Extremely important for giving u
more time to time braking and see Crashes up ahead.

It doesn't change the AMOUNT of detail, it changes the DISTANCE at which
details become noticable.

From my experiments a V3 2000 (i.e. 143MHz) has same fps as V3 3000
(166MHz). Main factor is CPU performance - moving details slider right
strains the CPU as it has more polygons/triangles to prepare to pass to
the V3.

Anyways, 733MHz looks good - I'm at a mere 450MHz which I OC to around
550 for races which is ok so long as I keep the details slider 25% left.
I saw the latest Intel project of its P3 prices that came out today and
am starting to plan forward to when the P3-700B crosses my upgrade price
range (probably in about 3 months time :-)

Actually, it is the same. The LOD is less at an given distance. Thus
the amount of detail will be less after a given distance.

Thanx for all your replies. Now I have to find a way to get my processor up
to 850+mhz ;-)

It changes the amount of detail on my machine Bruce - set it real low
for that funky "hexagonal tyres" look. (Actually, I quite like that -
it makes the car look sort of futuristic).

Oh? I tried that and I don't get that effect, Richard.
(What I meant by my original response was that the slider doesn't add or
remove detail like the check boxes do).

The wheels are drawn with less polygons still, so they become blockier
with less detail (on my Voodoo2).
