I'm sorry my English isn't very good.
So Mr. Chronus is right that GTR2 is not unrealistic.
And I like GTR2 and that's the only sim game I play.
I'm with you on the good base physics engine!
To be honest, however, I thought the braking in iRacing seems to be somewhat better if in fact all the above is true. Maybe better isn't the right word - my English fails me (as always).
Braking in sim racing is rather different from the real life braking, because brake pressure just cannot be translated into pedal travel very well.
Also, some sim racers seem to think there is a 100% pressure point (the end of pedal throw) in real life when there isn't anything like that in RL.
My understanding is that if your braking doesn't lock up the brakes, you can progressively brake harder (more pressure) for a fast laptime, because there is no maximum pressure in real life - "the strength of your leg is the limit" unless you can rupture the brake hose or something like that.
So first you have to learn to lock the brakes as quickly as possible.
At least that's what they teach in racing schools from what I understand so far.
And in GTR2, there is the default 100% pressure setting, which is of course non-existent in real life.
Whereas, most of the iRacing cars have no pressure settings? so that seems a bold move, since some may develop oversensitive braking issues because of that. That's all: a bold move.
Actually, I've found that there's this Japanese guy with a soft pedal and he is having a very hard time in the iracing's star mazda because he is used to sim games where you can brake "to the plastic" (100%?) most of the time. He in fact wrote he didn't like iracing because of that.
Also many people seem to complain that the brakes in iracing are too strong or something.
Just like many people did about the brakes of Mr. Niels Heusinkveld's historx V1.0? cars...
That being said, however, I have to say I like GTR2 the best because I can just customise it!
Also because of this point!

Recently I've been doing some research and found out all this and about the importance of the threshold braking in real life motorsports.
So I don't know about F1 and I doubt there's any normal person outside F1 who has actual technical info on the brake pads and the tyre slip curves and stuff, because you can't access that kind of "sensitive" info if you're outside the contract (that's what I read).
But what puzzles me is that if you couldn't in fact lock the brakes of an aero car
, racers would definitely have bodybuilder legs by now
to be able to brake with over 1,000 lb/500kg pressure (yes, bodybuilders can do that), since more pressure or by most sims standard say 200% braking should lead to less braking distance...
That is, racers are very competitive so I think they would do almost anything to become fast. Therefore, it follows that they'd develop bodybuilder like leg muscles or anything like that even if it means say one tenth faster in few corners in a qualifying session, for there is no full pressure in real life. I know I would do a lot of leg presses because it'd take less effort to brake with that kind of pressure.
So maybe the HPD's downforce is insignificant and therefore not an aero car?
I'm not sure whether the HPD qualifies as an aero car (looks pretty fast though
) although I understand F1 cars are, but still not sure about Formula Nippon or SGT or FJ like Formula cars or what amount of downforce the aero car should generate for the qualification.
I do not think this kind of discussion leads to anywhere unless you're involved in a racing team like Mr. Heusinkveld. Of course, it's essential that one needs to have learned to properly brake in a racing school.
Anyway, if in fact you can lock up the HPD's brakes at high speeds in iRacing on the high pressure setting?, in my opinion, iRacing is "reasonably" decent and realistic.
I'm not looking to "sim drive" fast cars though.
The needed pressure for most race cars would be something like 80kg, so a lot more than most production cars' 40kg (roughly) and I've read that most people are unable to lock up even production cars' brakes because they are not used to registering that much pressure at once.
My attitude towards sim games is that they are still just video games. So pretty lenient.
That's not to say, however, games like Test Drive Unlimited (which I liked a lot) are in the same category as iracing? or GTR2.
So I'm not too concerned, but in the mean time, I don't like some sim cars like the default production car from my rFactor demo - it makes a brake hiss sound but no tyre screeching even when absolutely piling on the brakes, so that's kind of extreme for a car that's meant to race.
All this may sound like a Zen koan in English, but I believe everything has degrees of truth in it and if it's too serious I'm not sure it's that good.
I understand it is confusing when it comes to the braking in motorsports because they used to believe braking in a straight line is always faster or something like that.
And a lot of racers say kick the brake pedal but some hard braking looks progressive and not exactly a kick, so like darock says, it's true "brakes are variable" to some degree (very nice way of putting it).
However, the important point to stress here is that a great many sim cars are like that rFactor car regardless of downforce, so this may be contributing to the idea that race cars brakes won't lock up.
I can think of many sim cars with some or even no downforce but all of them have the same no good brakes.
Again this to me, is not that good but if it's moddable, the problem solved!
As for the sliding behaviour, if it's THAT serious, I may not like it, but I think it's ok for me.
The biggest question for me is, I'm pretty much satisfied with GTR2 with my customisable brake pressure setting, so would I like to go into the waves of those competitive/aggressive people and race? Probably not at the moment maybe....
Thank you guys!
Sorry about my English.
