Physic discussion thread

We have a long topic in beta but a similar one may be interesting for other contributors unable to access the specific forum.
As the community (hopefully) spreads, I think it would be beneficial for all to stay in the same place (at least for everything it's working in the same way on the main release).

 

I just wanted to point out for confused readers that this and its surrounding comments is roughly where this diff discussion stems from: Automobilista 2 V1.1.0.0 RELEASED - Now Updated to V1.1.0.1

I have to try this. Sadly not a globally user applicable fix since many cars have fixed clutch LSD values in the setup. But will surely take what I can for now .

I'm glad to see more discussion about this out in the public, because it felt like nobody cared or saw this. Of course that wasn't the case.

The discussion in public is mostly just valid descriptions of what different players are feeling. Like the "no liftoff oversteer" notion from GamerMuscle. It's annoying when some people - and I want to be clear that I don't think GM ever said this - jump to the conclusion that Madness itself is somehow doomed to fail like this.

 

In the above graph the wheel are perfectly differentiated for the 620R in 4th gear at 180(!) km/h...



Also here it seems to work quite fine at bus stop exit in second gear.

For the rest of the lap, no matter the abuse the speeds where exactly the same (even starting with one wheel on the grass and the other on asphalt).

 

Umh, apart from bus stop I had a possible reason why it's working in that way, but the slippage there ruined my theory...

 

Hi @oez

As @CrimsonEminence and @Avoletta1977 have indicated the Diff discussion goes back in Beta as well as main
not sure if you have seen any but here is just 1 link Formula-Retro drivability

 

So whats the go? What needs to be done?

Seem to remember patch notes about this in a dev diary thing. Seemed it was put on the backburner for a time. A choice was made etc. to get perhaps repeatable results, consistency rather than nuance.

Madness engine been around a long time, many iterations, its something that can probably be seen to now cars tracks, tires is well advanced along

 

Its already been suggested by above but elswhere
Devs are aware and I for 1 remain optimistic and confident that the "further polishing" and constructive feedback will yield results but like above its a little frustration time wise. Brabham bt44 in particular for me, as a favorite car. However the Gt1 merc and procar will keep me ocuupied for a while.

 

Thanks for the post. Just so happens amazingly I wrote this at the same time in the other thread - that it sounded like at the time it was a deliberate work flow thing which now you mention that would (we'd have to go back and read) accomplished a few things, so they went with that, in order to like you say hit on other things.

My quote:

"The madness engine has seen many iterations. They will get to it. BMW challenge on madness engine probably had super naff differentials haha

I spent a good deal of money on this setup - almost 2 thousand dollars - and I do not feel jipped by this game or the others like Rfactor or ACC. So I totally understand you when you say about differential and being close to the actual thing etc. I often adjust the dif settings, depending.

I am pretty sure they will get to it. What I am seeing is a workflow thing, not a 'brain drain' thing. The differential needed to be a repeatable results thing - the guy fronting the project said that basically (iirc) a few months back.

This helps them out the diff thing, its allowed the game to do other things in that time. They will get to it."

The old formula problem/solution - new numbers, new results. Would appear to be easier than ever maybe to implement this. Though the implementation is 4/5ths the cure in this.

Oh well. The more one drives the more they come across these things. Guess it will be ironed out.

I am not a mechanical engineer so I can't help with that - but what I do know is that now most of the cars are in the game, from a project standpoint, now they give consistent results and are complete - they can probably change something as crucial/central as this going forward.

 

Played AMS1 yesterday again.

Indeed, as you say and some cars more than others; and yes this is a sticking point that will make myself turn away too. More real cars is definitely a notion that is easy to grasp and would make myself like the title even more. Probably most people. The recreation of that certainly is the draw of the title. At the start of the title I could not believe (in a good way) the way Bathurst had been recreated - that kind of excellence.

I might say the analogy for driving believability can break down, or in general I often say where does the analogy break down (like in modern physics from the huge [planets etc] to the very small - atoms - the analogy or the theory breaks down.

Thus this could well be a case for less complexity or more. Maybe a simpler model for those without it, giving two models.

So you guys certainly have it pinpointed. Do you think they have a second computer where an early model of such a thing is being worked on outside the main branch of code?

 

This was particularly noticeable round julyish - and was frustrating to be honest.

I gave everything 85 ramp and yeah, those days are gone now thankfully - off throttle turning seemed to not make a difference, and thus people myself included would throw things into the turns; probably much like the comment a few above from someone.

 

Ginetta GT4 in a kart track.

130 Nm Preload 89-89 ramps 2 clutches


30Nm preload 89-89 ramps 2 clutches


Cat 620R default setup



So, in some cars the Clutch LSD quite works apart from the extreme influence of preload.
In some don't... like at all.

Driving the cars on such a narrow track is quite revealing anyway (the 620R is simply terrible, while the Ginetta is nice... even the lift off oversteer is working when opening the diff in coasting and using low preload).

 

ok well that would be because I do not drive all the cars to such an extent, and am particular about which cars I drive on what tracks.

eg strangely I like rfactor 2's 650, thus I do not drive it in AMS2.

I consider the gen 1 classic f1 to be in such a category and the more powerful caretehams. Unwieldly.
