Is there a limit on the number of skid marks after which new ones make
the old disappear?
I had this bright idea of laying down some *** on my outlap as a
guide to braking points (espec. Rouen - my problem track) but it isn't
working!
Is this perhaps a memory limitation? (PIII 550 256Mb G400).
Thanks,

Mmmm, I tried to write my name on the straight at Monza and ran into the
same problem :-)

I guess it will just kill the framerate too much if there are loads of skid
marks, and I'm sure some clever person can come up with a way to make more
skid marks!

Yes.  Here's how to prove it.  Take the Lotus.  Hold the brake at 50%
and shift into first gear.  Floor it!!  And slowly put the brake in
until you are doing a burnout.  You'll put all the blackmarks in one
place.

Or you could do donuts and after about a 1minute, you'll see the skid
marks disappear at the oldest point.

Drive faster while making skid marks. ;-)
It's a ring buffer of polygons, where in the end you'll eat up your
old skid marks and create new ones.

OK, thanks, I'll give up on that one. On to Plan B (practice,
practice, practice!)

I'd say if you can't remember your braking points, this could well be down
to a limited memory ;)

Yes, something to do with old age - a problem I share with the
software.
(No-one else has ever come out of the hedge at the Ring and then
proceeded the wrong way down the road... have they? No - but I did it
at Mosport last night!).
I have limited my ambition to suit - to get under 107% at all tracks.
Only 3 to go - Monaco, Rouen, Ring.

I've ended up going the wrong way at the Ring, but not at Mosport :)  Have
you got the racing groove turned on?  That's what I base most of my braking
points on.

Yes - when I first started playing GPL I thought "This is where we
brake". Erm... not a good idea - especially at Mosport, just on the
crest of a jump, and at the penultimate corner at Rouen (after the
fast straight) - much too soon.

Piggybacking - I never saw Laurence's original message...
Do you mean 107% of the supplied replays, or 107% of the WR's?  Big
difference...<g>

Well, you have to remember how much into each dark groove to start braking.
I try to remember it in time, so I brake a second, or half a second (or
whatever) after the groove starts.  It sounds like the kind of problem that
should be solved by just doing lots of laps until you're really intimate
with the circuit.

If you've already done lots (like >100) of laps then try some AI races
instead, since for some reason racing a circuit always helps reinforce in my
mind the corner speeds, gearing and braking points, way better than just
hotlapping can.

107% of Papy times. Those WR times seem just impossible - 3:11 at
Spa?? My PB there is 3:32 in an Eagle and only touching the brake
once.  It wasn't a specially hot lap (for me), and I can see places
where I could gain 3-4 secs in all by getting on the throttle earlier
but I cannot understand where that time comes from. Wish replays could
show throttle / brake movements.

But I reckon I'm having as much fun as many twice as fast as me, and
although this is a simulation, not a game, fun is what its about, yes?

Yes, racing AI was how I learned the tracks to begin with.
But I can't go fast that way, because:

a) I get a bad FPS drop down to 25fps in Practice or Race at times -
affects control badly, even at 640x480 with detail turned down -
Noveau Monde jumps at me in flicks
b) When I can go faster, eg get T1 at Rouen right (back end just about
to hang out) then I'm faster for T2 and need to brake earlier, get
that right and even earlier brake for Nouveau Monde.

I can do consistent slow laps, but not fast, and don't seem to be
picking up enough cues to judge entry speeds correctly - eg I've got
braking for the Chicane at Monaco right a few times but I've no idea
how, replays don't show me where I braked and how much.

Never mind, it's good fun and nobody gets hurt.

You must use your brakes! It's *much* quicker to come zooming up to a
corner, slam the brakes on, turn, and accelerate away, than it is to just
coast gently up to the bend, off the power so you can make it round without
braking.

I assume that if you only touch the brake once then that's to slow for the
La Source hairpin. From memory I think you also need to brake in Eau Rouge
(just a dab), Les Combes, Malmedy, possibly Masta, just a dab at Stavelot
and another at La Carriere (that's the *** 3rd gear righthander before the
long straight up to Blanchimont). Brake at Blanchimont too. In fact the only
corner that you don't really need to brake in is Burnenville, unless you
fancy a short dab halfway through as you're changing down to 4th gear.

If you watch replays with the "front bumper cam" view, then you can see when
the car pitches forward and back under braking and acceleration. Not always
100% accurate but you can get a very good idea of what braking points
someone is using in their replay.

Hope that helps,
cheers
