DON'T DO IT! Richard, for your own good, do not - I repeat DO NOT -
start the "30 fps is all the eye can distinguish" discussion again. I
know you're not saying this, but it's dangerously close. :)

Really, this is a topic that leads to regular RAS flamefests every six
months or so. And the side that claims that framerates above 30 fps
are overkill always loses.

Some not-so-dry numbers to back this up:

Auto Union V 16 1934 model: 4.4l, 295hp at 4500 rpm
        type B  1935 model: 5.0l, 375hp at 4800 rpm
        type C  1936/37:    6.0l, 520hp at 5000 rpm

Our GPL cars have less power at double rpms. Just imagine the torque.
:)

And the cars weren't slow either: Carraciola set the world record in
1938 with a 5.4l Mercedes with 600hp: 423.7 km/h (that's over 260
mph). And we thought GPL cars were scary... :)

That and the fact that any running example of a 1930's Silver Arrow or Auto
Union is worth upwards from two million dollars US, as if anyone would sell
one<g>.

I had the good fortune to see Fangio run some demonstration laps of the Long
Beach course before the '76 Grand Prix in one of the pre-war Mercedes, at
one point making the uphill right hander from Pine Ave. onto Ocean Blvd, he
had the car in a beautiful 4 wheel drift, engine screamin'  with this big
ol' ear to ear grin on his face. In the right hands, these cars were very
fast.

Heavier, yes, but the power put out by both those cars at their zenith
(1939) was very high indeed.  Make no mistake....driving these things was
not for the faint-hearted and if the physics are being toned down somewhat
in the sim then that's fine by me! :o)

Tyres are available from manufacturers, in some cases 'off the shelf',
sometimes custom made. They use more modern materials, and are better than
the ones used in the thirties. However,  the tyre shredding monster Auto
Union and Mercedes Benz cars needed exceptional drivers to handle them. The
Auto Union was a notorious pig to drive, and only hero's like Rosemeyer and
Nuvolari could tame them. No wonder that these cars are never given their
head today, despite tyre developments.

  These are not the framerates we're looking for.  Go about your
business.

Nobody said cinema.
Cinema = 24 fps
Video NTSC = 29.97 fps (~30)
Video PAL  = 25 fps

Where video does things in fields to complicate things. Thus Video
frame rates are actually doubled, but flicker a bit depending on the
phosphor used in the monitor.
Cinema is great, but is sure is jerky when you see some panning!
Ah well, we've seen these discussions before.
Around 120Hz the discussion ends for all people I guess. Although
probably many will still prefer 130Hz over 120Hz ;-)

But he's very right about the jerkyness coming into play when the
frequency is *not stable*. It's more irritating to see a 30Hz picture
move every now & then to 25Hz than to look at a stable 15Hz picture.
Just watch cartoons...

Mark, I believe at least one of the European manufacturers (Dunlop, maybe?)
does produce a small run of various "vintage" tyre sizes and compounds. I
have no idea of the details, however.

Yes all that is true except hz as in screen refresh has nothing to do with
FPS, you can have 36 FPS in GPL with 80hz refresh rate, whitch is stable
enough. Anything under seems very flickery to me and hurts your eyes after a
while.
