stonespike you really have no idea about racing simulations

Forza 2 has a physics engine running at 360 cycles/seconds and has a render framerate of 60fps. That's a technical achievement in itself but the amount of physics data that is being calculated is quite superb.

This is I think the reason why the graphics aren't the best we've ever seen (and stop whining about them, they're very good), if you for instance bring up the telemetry data for the car by pressing up on the D-pad you'll notice all the real-time calculations the engine is doing but also that the frame-rate dips when you access it. This leads me to believe the physics engine is pushing the system as far as it'll go.

If you haven't looked at the telemetry (real-time telemetry is a big-deal), this is what you can observe:

-Current engine characteristics
-Current car velocities
-Tyre friction
-Suspension deflection
-Body acceleration
-Tyre misc. parameters; Real-time camber, tyre speed, tyre temp, tyre pressure and wear %
-Real-time heat for different parts of the tyres/engine

It's quite staggering and then if you think about all the differing levels of suspension parameters taken into account, car customisation alterations to physics and downforce....well, I'll just say that to calculate that stuff you'd need an engineer and alot of paper to get that data.

Oh if you want any slight proof of this, go and crash the car into a barrier or into another vehicle. No console racer has ever modelled that so accurately
