Now I know GPL has better graphics than F1RS, but F1RS is certainly no
slouch with very good graphics in it's own right. Now my problem with
GPL is the fact that with graphics that are only marginally better
than F1RS, why the heck does it need to run like a dog compared to
F1RS on a comparable computer. With 22 cars in F1RS it's super smooth,
much more smoother than GPL with only 19 cars on the track. And don't
tell me that it's the fact that the "far superior" AI in GPL is the
reason why it takes so much more computer power. In my mind, F1RS's AI
is very good and not far off GPL's.

For everything that GPL is, it does a major poor job of running on a
computer. Come on Sierra, you can do better than that!

PS: You would think Sierra manufactures computer equipment.

In my mind, F1RS's AI
F1Rs AI cars are a joke.They don't obbey physics laws.You can feel this
clearly when racing in the rain.AI cars run at impossible speeds on certain
turns,like on the stadium complex in hockenhein.
AI being agressive is not bumping at your rear when you brake at the right
point and simply there's no place to be overtaken.

the difference? the difference is in the simulation of the car's
physics. Sure, GPL has more advanced AI, but the AI routines themselves
don't really take up all that much CPU at all - it's the physics
of modelling each car that sucks up lots of CPU time. F1RS has
pretty simplistic physics which is why it can run so many cars without
impacting the framerate much at all, while GPL has much more advanced
physics requiring significantly more processing power.

It's not, actually.
It's the extremes of physics modelling that takes the CPU poer.

So M Schumacher was not aggressive when he bumped Coulthard's rear?

Two reasons. One is that GPL models _vastly_ more of the car than F1RS
does, and runs it's physics engine several times faster as well. On
top of that, in almost every sim I've seen the AI follow a set of
predetermined lines at predetermined speeds, following some rules to
overtake or avoid other cars. The GPL AI cars obey physics also, so
it's not just one car the calculations are done for, it is up to
twenty!

When you take that into account you can see GPL is actually very
highly optimised given what it is doing.

Cheers!

No,he was just as stupid as F1RS AI cars .And just because his
"agressiveness" on that race,today he would be in a much better position to
win the championship.

Interesting info.

But with my critical mind, I immediately get to this next question: is this
really NECESSARY???? Does it really matter? Wouldn't it have been faster and
just marginally less sophisticated to simplify the AI cars? Would anyone notice?

I don't own GPL, so I don't know. Just a hypothetical question.
