i've had the physics running at over 3000hz on my P-3 533 (without it getting behind)... so. um... something is odd alright.

and I'm currently running it fine on a crusty Cyrix 233 (effectivly about the speed of a 133)... at 2fps in 640x480x32... so.. considering it doesn't have a 3d card as well, I don't think thats the problem.

I used the same code as this in my lotr demo. and odly enough nehe had it run very slow until he recompiled code that I sent (the original code I sent was set to use some uneeded DX dlls)
I might try a recompile on this cyrix. see if that does anything interesting.

kinda strange.

Ran fine on my 800mhz cheap o''depo MOBO and an athalon chip with 128 ram (my work system) and an old tnt2 graphics card.

This vwas very fun, but i only saw checkers which was disappointing but it was fun when i flipped the truck and i keep rocking back and forth and when my tires hit the ground they kicke dup dirt! LOL! This was very fun, and it does have a little too much over steering. Tell me, does this 4WD monster have a 700R4 in it? LOL!

Do you have any plans to release the source?

You've done such a great job.. I wish I could do something like that ..

Anyway, I was getting ~40 FPS on the first one and ~15 FPS on the second..
PIII 733
Integrated video
128 Mb of RAM
1024x768 @ 16bpp windowed

Good job...

Runs around 25-30 fps on this setup:

P3-500
GF2 ultra
384mb RAM

First one ran about 30fps so no significant drop for me. Nice physics but i''d like some more friction cos i keep rolling the car all the time

Doz

I have a Athlon 1.4 / 512 / GeForce3 and it runs __ s l o w __ on vehicle2...

Like 15 fps or something - regardless to the resolution... 320x240, same fps as 1280x1024...

That''s because the terrain is rendered brute force (NO culling whatsoever), meaning all of it is drawn every frame.

Comon Graham, put in at least a frustrum cull.

it runs great on my p3 800mhz geforce 2 64mb setup with a 1280x1024 fullscreen resolution, i get about 30fps.

riptorn, if you put a frustrum call in there and gave it some, well, friction, it would be really really really fun. and maybe some other cars but that might slow it down too much

Nice demo! I got great framerates even in a window (gotta love GF3), my only problems were eventually running off the edge of the level, and that sometimes the car is difficult to control when you respot it (insert key) because it can bounce off the ground and flip over.

P.S. for anyone else following this topic with the intention of making a demo like this for the first time, the tutorial at http://home.planet.nl/~monstrous/tutcar.html is one of the best I've seen (I downloaded about 5 different ones before I ran across that). Also anyone interested in the source behind this kind of thing might want to search for a tutorial and accompanying source code on rigid body dynamics by Richard Chaney.

Strange. Everybody has such low numbers. Is a GF4 so much faster?

I get 240 fps for the first one and more than 90 fps for second one. Both in 1024x768 32bit (window)

I have an athlon xp 1700+ with a geforce 4 Ti 4600.
