Isi sims don't fully replicate the human car's physics, but they do
allow for almost unlimited separate types of cars. Whereas, the Papyrus
engine, although capable of multiple car types, was limited, most likely
for performance reasons to at best 3 or at least 1 AI model.
Papyrus sims, to date, do not have dynamic weather, depict rainfall, or
other imersive cpu intensive features.
iRacing so far is 'showing' 3 types of racing, If I recall, they all are
either single car type or, if multiple types, very similar in performance.
It will be interesting to see how many features iRacing piles on to their
core GPL-based code.

Its true I haven't optimized the collision detection or the physics at all
yet, so the code is putting a huge load on the CPU.
There are still many optimizations I can make in many areas of the game and
plan to get around to it when time permits.

As for now it requires a mid to top end machine, reducing the number of cars
in a race also helps.

I almost guessed so. While many new sims simulate a lot of stuff, I
sometimes wonder if they don't suffer a bit from the rush that seems to
afflict so many other computer games today. Many titles today aren't
ready to play when released!

I guess a home brew have all the time in the world. So much better! :D

It is? Didn't know that.
