Rfactor2 or AC? Not necessarily on looks but which is going to be the better multiplayer? with the best RD club races etc etc? Keep thinking of buying rF2 but don't want to get it then AC becomes the "main" event.
'the camber issue' lol... you know it's impossible to detect on stock content right? That's how small it is. if you can't tolerate bugs in a sim then I have some bad news for you re: rF2. They're literally changing tire parameters on every car right now, if that's not a compromise on physics instead of having everything perfect, I don't know what is.
It's been like that since AC came out in 2013 and nobody noticed until recently. The devs have a better shot at spotting mistakes than players but they can't work magic. If there are detectable side effects of the bug then they can look for it, but if they don't know something's wrong they have better things to do than contemplate the physical accuracy of every line of code.Also it's quite worrying that they don't even notice them while they are doing their own cars.
If what you care about is simulation, then there's no difference between a bug that sets a parameter to 0 and the parameter being set to 0. They both make the physics wrong the same way. If you want to get into finer distinctions, you need to examine the scope and magnitude of the errors - say, a bug that makes it half what it should be vs. the parameter being set to three quarters what it should be. In that case one is better but they're still both wrong.They are adapting the old cars to the new engine technology, like AC did when the last tyre model was introduced. Comparing that to bugs ... lol.
I hate to be the one to say 'major disinformation' but that's literally what the version changes on AC are, adding details to the existing model. Most recently they added multiple temperature layers, more flexibility in the load sensitivity curve. Sure, it replaces the old implicit surface temperatures - like how CPM replaces the old parameters for contact patch deformations. (which, if you've seen how much deformation you got even on stiff tires... yeah, probably a good move)things like the CPM model being added to cars, unlike Iracing and AC this isn't a new tyre model version, but simply more detail added to already the most complex tyre model on the market,
I wouldn't expect any different, kunos is fairly new kid on block with a new engine, how can you even expect a small team like that catching up on teh many many years ISI has been working on their product
That's true up to a point, you can observe the number of parameters and say it's higher. Doesn't mean it's more realistic, but it is definitely more intricate. If you're looking for the most real, the best option is to capture the physical laws and implement them - the next best option is to parameterize the performance envelope so that on every point you've measured, you have a parameter to let it match. The danger in that is twofold of course - first of all, it's very possible to fit to bad data - with such a complicated model, there are no telltale "that value's simply not possible" because you can't know enough about what the parameters mean. If a data point suggests the tire was at -10 psi during braking, you'd say "no, the sensor must have been experiencing difficulty", if it says that a32 is 1.375 when fitting that same point, you need a great deal of experience with good data to say that's not an acceptable value of a32. Second of all, behaviour outside the measured envelope is much less likely to be sensible - one big place this comes up, no tire dyno can observe large slip angles - past about 10-15 degrees, if you have a realistic load, the tire simply cooks without ever reaching a steady state you can measure. If you run a dynamic profile (eg. sweep the tire 0 to 30 degrees) then relaxation length comes into play meaning the data's not pure, and so on. A more complicated model is much more likely to spew out complete garbage when faced with situations that are not part of the measurements - there's just more to go wrong, working at extreme values amplifies faults in the data/model. This is not a problem on a professional simulator, because they don't intend it as a general purpose tool - if they can't simulate a car on two wheels, they just don't run scenarios with the car on two wheels, if they don't have collisions modeled, they just don't run scenarios where the car hits things, etc.ISI tyre model is most complex out there fact, ISI lays it all out to see in its intricacies.
I see that you are stuck at the "elite" thingy, even though no one has claimed to be an elitist.@Hash_V8 they are the self proclaimed elite, their words, not mine. see post #31 & #33.
The road cars seem very nice in rf2, (the corvettes and nsx) but the quality of the content as a whole seems too inconsistent atm, some tracks that im pretty sure were from isi in the workshop just felt very poor quality in terms of surface (similar to the bad rfactor 1 conversions for ac that have tri's stretching across the width of the track), and some of the cars felt really wacky, although possibly i didnt have real road set up right for some of the combos i tried (the inconsistency in some tracks supporting it was kind of annoying too), for now i got a refund and will wait till its next on sale and see if the content is more consistent in those respects.I haven't been here on this forum for a long time. Today, I came across this thread and was curieus about rFactor 2, so I downloaded the demo and gave the Corvette a try. Although I like AC very, very much, I'm not a fanboy. AC has it's faults but the driving in AC feels very good.
After playing rF2 for a while, I have to say that this sim feels very good as well. Too bad for the very old and almost dark ages graphics. I enjoyed the driving in rF2 as well. If only the graphics were on par with AC's or even pCar's graphics. I can see the attraction of rF2. It is definitely a sim to keep an eye on. The weight distribution of the AC road cars is soooo good and realistic (very good suspension model in AC). I can't judge this feature in rF2 because there is no road car to be tested in the rF2 demo.
