ACC Blog Aero. I believe I can fly…

    I hope the (aero) damage system will be better than in AC - stuff like damaging the front splitter on curbs, damage to dif or loss of winglets here and there.

    The old one was kinda silly, it never felt like the balance of the car changed much, rather that it was just x% slower and lost top speed (correct me if i'm wrong).
    To me it seemed like with some cars you were suddenly an easy target on the straights after some minor contact but sometimes an all around yellow car on the 'aero' parts/body after being punted several times in an open lobby on the very first lap was potentially good enough for a top5 lap (RSR - though i don't use it) on the 5th lap of a short race

  2. You’re wrong. Balance could absolutely be affected from damage.

    On all cars automatically done by the game or did it have to be put in place?

    I mean it was just my subjective feeling anyways, we used to turn damage way down on our server to the lowest possible setting after some time (without turning it off) because the effects of the damage were very weird at times (like the aforementioned loss of top speed from slight contact)
  4. So .. um. Thankfully my kids were in bed when I was reading this. Because, eh, I had a solid boner the whole time and I didn't even notice until I was done...

    I'm looking forward to the wing interplay but am skeptical about the importance of aero on GT3 cars. With a CL = 2.7 thats only ~350 kg of downforce at 200 km/h. A static balance change from 48% to 50% for a 1mm ride height delta is only a difference of 7kg. If the splitter & diffuser are more sensitive to ride height and rake angle in ACC, that'll be interesting. In the end softer springs and dampers on GT cars will give you much more grip in more situations than to stiffen them up and get the aero stable - that's more relevant for LMP & formula cars.
  6. CL=2.7 and air density=1.2 (20 Celsius ish) is more like 500 kg of downforce at 200kph. In any case, softer springs all around don't really help cornering (the load transfer is always going to be the same) unless the track is bumpy.

    Like some others have said, it's starting to sound a bit intimidating. I mean, we are armchair sim players, not real engineers. Will we have any hope of making setup changes that we actually understand the impacts of, without totally screwing up the handling?

    Wouldn't be Assetto Corsa if the solution to some problem wasn't "just add understeer." lolol

    Great question I was wondering the same

    This is what Aris said on his Facebook profile, answering to a similar question.

    "You're gonna get base setups and % delta of aero balance shift as you modify the ride heights. More is in the works too. Plus of course, remember that in a sim you have infinite tests and no problems when you crash ;)
    Generally we're trying to give the correct amount of help, without of course showcasing the actual real data as it is under big NDAs

    There will always be setup download sites for the weak. (like me :oops:)

    Have always been rubbish when it comes to setups, doesn't stop me enjoying whatever sim I'm playing :)
  14. So same stuff as we did get in netkar setup screen but was removed on AC

    WOW! This is totally amazing. Awesome developments. This is the Holy Grail of sims to get to this level of fidelity.

    Out of interest, what are the downsides? Extra CPU processing? If not extra CPU load, how do all the numbers get crunched?
  16. It’s just a lookup table with 2 inputs (front and rear ride height) instead of the 1 input tables we have in AC. If anything it’ll be faster than the AC version (because it’s technically less complex). Not sure how wing angle adjustments will be handled; it’s not been mentioned. Those might add a (tiny) bit to the memory load, but processing shouldn’t really slow down.

    I agree with this view regarding the wings app, i'm 100% in favour of it being an option.

    Different aero maps depending on your wing choices?
  19. Potentially, but it seems like a lot of unnecessary work for Kunos...I've never seen a full aeromap recalculated by the manufacturer for rear wing adjustments on a car where it won't really affect the rest of the aero, there's not much of a point in doing so. They certainly won't have done such a thing at a wind tunnel, where wing angle changes are usually measured as a % delta (or absolute delta) at a reference ride height. So Kunos will have (had) to do it manually...Also what if something at the front is adjustable? Then you need a set of aero maps for each wing adjustment (for example, 4 adjustments at the front and 10 at the rear, and suddenly you need 40 maps)...I'm not sure how they've decided to handle that. It's where the "wing" system is particularly useful.

    I beg your pardon? Softer springs don't always mean more grip. This only applies to uneven roads to compensate for bumps, but on flat roads, harder springs mean less lateral tilt and therefore less shifting of the centre of gravity to one side and therefore less lost of tyre load for the inner wheels, so they lose less grip. Of course, the outer wheels of a corner build up more grip, and the more load they bear, the more grip they build up, but the grip increases degressively with load and increases less than it decreases on the inner wheels, which is why lateral tilt always means a loss of grip, the higher the increase.
