David Greco's Handling, Driving and Setup Q&A (?)

@Meza994 your turn now! Just a few observations from your discussion with David I was shamefully too late to chime in!

Porpoising. Actually this is not directed at you as I think we're on the same page. In my opinion it’s misguided to want porpoising itself in the game.

It is simply a consequence of the continual choking and relief of the underfloor downforce. Adding porpoising for visuals sake only sounds exactly as Codies said already: a waste resources on something the players would turn off in a heartbeat. To this day we still have people turning off motion blur straight out of the box, imagine porpoising?

Then again, porpoising is but a consequence of the revamped gorund effect in these cars. What I’m always looking forward to and in my opinion should be the major focus here is further simulation of aerodynamics. We’ve got confirmation already that we’re getting 😇 proper modeling of downforce generation by each main aero component (front wing, rear wing and underbody) and (b) that diffuser stalling will be a thing, even if somewhat watered down.

Kind of not seeing the forest for the trees situation. 

Tyre loads. This is very setup dependent. The load bias i.e. how much you’re loading the front axle vs the rear axle is totally subject to how you set up your suspension and your wings, the latter increasing in preeminence  the faster you ago.

This whole numbers% game over youtube clips without proper insight into the setups being run by the players can easily fly over my head. I don't know how can you insulate your analysis from other factos and go all-in on load distribution just by eyeballing gameplay clips.

Now if the hypotheses is that the car may have too much overall grip, that's a different thing altogether and an easier conclusion as long as there's a solid method behind it. Like we discussed elsewhere, one I can think of is comparing throttle trace and speeds with real life telemetry data. Even so it would still be tough to rule out setup variables, but at least we could estimate a cornering performance that these cars should not be achieving considering their real life counterparts. 

I honestly don't know how one can reasonably figure out grip levels without knowing or at somehow accounting for setup, mechanical and aero balance, entry speeds, and throttle application.

Tyre load sensitivity. Surely you mean lowering the grip at the lowest data points as they are seemingly too high as per your scrutiny? I think you mixed them up here.

Greco is referring to something like this:

Obviously you should disregard the values as this was a quick grab from Google Images.

The point is, if you think the tyres’ load sensitivity being off is the cause for slow corners being taken too fast in the game, that means that the tyres are generating too much grip (high "y" values) for too little load (low "x" values).

Just my 2 cents!

I turn off motion blur and would also turn off porpoising in a heartbeat.. it’s pointless and adds very little to ingame emersion.   As there would be a setup that would dial it out and as soon as found will be on every youtube and setup site.  And like brake bias meta off 50.  There will be only the  meta setup to cancel out porpoising.
