Tires and Suspension model?

Hi to everyone.

Found two interesting videos about tires and suspensions in GT Sport Gran Turismo SPORT Beta 1.07 | Tire Flex & Deformation under the car weightload (Video+Screenshots) - YouTube and more awesome in PCars2 Project CARS 2 - Renault Clio Tires and Suspension - WIP - YouTube
And i’m woring that Turn10 didn’t show nothing about that. New weather, sky and of course 4K and la la la, but what about physics in the game? Will Forza become an arcade game? Any information about that question?

Physics don’t impress the general public, and visuals make a stronger first impression.

E3 is all about first impressions; Turn 10/Microsoft typically avoid going into detail about Forza at E3.

Define: Arcade Game

No, and you likely won’t hear anything until September.

They’ve got Horizon for visuals already. Of course Motorsport should look good too, but there is strong feeling that Turn10 focuses only on a visual effect.

Like PJTierney said Turn 10 avoid details at E3. Generally from experience, news starts to trickle through after E3 through various sources in regards to physics. As for the feeling Turn10 focuses only on visual effects I disagree. FM5 changed the physics considerable over FM4 especially with the suspension model. FH2 used the same physics based system of FM5 which was far different to its predecessor FH1. FM6 improved on the tire model, suspension and pretty much improved the overall phydics of FM5 and PlayGround games before the launch of FH3 said that the suspension and tire model in FH3 was more realistic than FM6.

FM4 https://www.youtube.com/watch?v=h4QG3drCFjE

I tried to see the same effect in FM6 yesterday and nothing. Tried with standard tires and racing - the same, looks like nothing. I’ve never played FM4 but people say this is last good Forza at this moment. And with FM5 something goes wrong.

Last-gen Forza says “HI!”

The driving itself in FM5 was a major improvement over FM4. Being able to occasionally play FM5 at a friend’s and then coming home to be stuck with FM4 was a major reason I finally decided to get an XBOne. FM4’s cars felt weightless in comparison and rolled far too easily.

Lakiboom what are you even talking about?? who are these “people” saying such STUPID things? and most importanly, WHY you listen to stupid things? :slight_smile:

In fact tire deformation in forza is physics-based, and you can witness this on the clip I just made for you. upon spinup, when I turn slightly the steering wheel and change little direction, check what happens to rear tires.

When other games you present are out, then we will see if they are also physics-based and not happy animation time. :wink:

And especially for pcars2 dude… I had seen so many doctored slowmotion ebisu style fantastic videos for PCARS1, then I got the game on release. and my car would drive UNDER the tarmac… WITHOUT wheels… so yeah. keep hopes to reasonable levels on pcars2, my 2c’s

And your comment about forza4 being the best forza yet, dude, go get a cold shower :smiley:

Physics were a GIANT improvement! Car on FM5 felt so alive in contrast to FM4.

Forza tire and suspension modeling is still really far from Assetto Corsa. I would love Forza 7 to be more closer to Assetto Corsa than Forza 6… But no, seems like it’s pretty much identical to Forza 6.

everything has its issues, nothing is perfect
and assetto having over a dozen fixes on its tire model is a testament to that.

also, is there tire deformation in assetto corsa?

And what if you were to learn that ACs tire and suspension model was very crude and nothing more than velocity based. Would you still want other games to copy it?

Let’s face it, there’s no one here that has the first clue on how each developer has built their physics engine and how many separate calculations each is making. Let alone which one starts with the most accurate data.

We aren’t driving real cars on real tracks, we’re only playing games that give us an impression that we are. Which is most accurate is not necessarily the same as which one feels most accurate.

I believe AC’s tire physics are the result of a lot of hype and praise coming from PC elitist simmers. It is good, but not as good as the developers or hardcore simmers claim it is.

Then there’s Forza - something that falls in between PCARS and AC. CARS is actually brilliant physics-wise except for the oversteer issue. AC was a horrible experience for me actually - the physics were so floaty and understeery that I returned it the same day. Yes, this is coming from somebody who grew up on racing and motorsport and loves pure sim physics in racing titles. Now with Forza, physics are consistent across the board, however they are dumbed down on purpose to make the game accessble.

I hope to see this change and have the developers include a pure sim/hardcore physics model that holds back no punches. I know T10 is capable of it, but they are holding back. I hope they change their minds and listen to the longtime fans that made this game so great. I’m all up for more nuanced physics, YES please!

Turn 10 have been working with either Michelin or Goodyear since FM4 on tire physics haven’t they? And I’m pretty sure tire physics (tire deformation) have been part of the Forza engine since FM4.

They partnered with pirrelli on FM4, tyre flex has been animated since FM3 but Dan said that forza always simulated tyre flex but FM3 was the first time they visualised it.

Tbh I don’t think the tyre model has evolved much if at all from FM4 but the suspension model definatley improved on fm5/6.
