Let's talk about the rain 1.6

This statement is even backed up by at least one IRL pro driver (who likes AMS2, so no, its not hate talk).

 

I hated these puddles, though. Absolutely love racing in variable conditions, but AI ignored them - no traction loss etc.
Wet / dry line works quite nicely for me.

 

I made a post more than year ago that puddles in the game do not work at all / have been removed ? And it has never been fixed.
Reddit - The heart of the internet

I only ever race online so to me it means nothing what the AI does or does not do. On that note though the AI should have loss of traction implemented instead of completely removing puddles from the whole game that also affects racing online ? Just a suggestion.

 

It's strange that my post was moved here. I was actually referring more to VR performance, and the fact that rain and night driving are negligible.
Regardless of the simulation, aquaplaning and its effects require absolutely brilliant tire physics in dry conditions. None of the models in any simulation even come close to achieving this, in my opinion.
It's more about eye candy and fan service to offer options for buying the respective simulation. Reiza isn't doing anything wrong here. It's practically impossible to implement this in real-time for home computers, just like so many other things in sim racing.
There's more hype than substance behind it.

 

I've seen water on the windscreen being mentioned in here and i have noticed for a long time that there is something wrong with how it looks visually in ams2. I have had plenty of wet races in v1.6 where you could see out of the windscreen just fine even without using wipers. And that is because, in ams2, there is one crucial effect missing, that makes the wipers necessary.
In ams2, the only thing that impairs your vision during rainfall is the water droplets on the windscreen. In real life, however, rain also causes a thin film of water to build up over time on the windscreen if you don't use your wipers.
During driving, the relative wind hits the windscreen at high speed. This airflow is not perfectly laminar over the entire surface.
The fast-moving air creates shear forces and small pressure variations that destabilize the water film. The sheet quickly breaks up into tiny ripples and regions where water bunches up slightly thicker and other regions where it becomes thinner.
These small-scale thickness variations and moving surface ripples act like thousands of tiny, irregular lenses or prisms.
Each one bends and slightly deflects light rays in different directions which results in the image getting distorted in many different ways at once.
The brain can no longer fuse all these slightly shifted light rays into a sharp picture which means everything looks blurry.
The faster one goes, the stronger the aerodynamic shear, the more violently the film is disturbed, the worse the blur becomes. That's why wipers are needed, they mechanically remove most of the water and prevent the film from forming into this disturbed state.

Tl;dr: light needs a smooth surface to form a clear image and with water on the windscreen, the windscreen is no longer a smooth surface and therefore the image becomes blurry. And this effect does not exist in ams2.

 

Some points:

- We now have less puddles, but they Interact with tyres as usual;

- Windscreen effects in rain and waterspray at night are horrible: in windscreen, rain drops are invisible, and the waterspray is dark;

- For performance, to be playable and keep good visuals in VR in rain and headlights, keep shadows, track and cars reflections at MEDIUM, and particles MEDIUM quality and LOW density.

 

From my tests puddles are just a fake texture on the track and ever since that drastic change happened i never seen a real puddle on the track, not even once.

 

You can test in Hockenheim and thunderstorm, forms some small puddles, but they just induces tiny slides, not the old delicious acquaplaining of Interlagos missing pools!

 

I done a test in "storm weather" and there were only fake textures on the track like this. More rain only makes the track "slide more", there is zero water on the track anywhere. Tested historic version too, zero standing water anywhere.

 

The track to really try is Suzuka at turn 7. There always used to be a lake there.

 

What exactly is considered "Turn 7" at Suzuka ? While i do not want the tracks to be a lake, the fact that there is ZERO standing water anywhere is completely unrealistic.

 

Tracks do have drainage you know, not talking about Suzuka but in general. Plus not to mention natural run offs, levels etc etc. Therefore I find it strange you find it to be "completely unrealistic", standing water forms puddles which do not happen everywhere on a tracks surface, when it's not standing it's running off.

Edit: I maybe misinterpreting what you mean of course

 

Let's do the math... 47 AI vehicles, each with 4 tires = 188 tires... in aquaplaning calculations...

Which model should it be, and which one will Reize spend the next 12xyz decades tinkering with so that it works realistically at home?

 

20 - 26 cars from the 1970's on 1970's track which is about 80 - 104 tires and basically no drainage systems in place, yet none of the old tracks have any standing water. Is that realistic ?

Marked at 6:04 look at the huge spray of standing water on the edge of the track. There is nothing of that sort in AMS2 even on old tracks.

 

Realistic?

Do you want the truth about realism and sim racing? Mario Kart and AMS 2 are much closer to each other than to reality. Just because people spend up to €20,000 on their racing rig doesn't mean that a racing simulation is in any way truly, really realistic.
Sim racing is about as realistic as SimCity or a cooking simulation. A pinball game from Windows 98 is far more realistic than all the racing simulations in the world combined.
A car has 50,000 to 100,000 parts. How many of them do you think are actually subject to calculations, and how accurate are those calculations?
Calculating rain and aquaplaning is practically the pinnacle of physics... and that's supposed to happen in real time, on PCs from the local hardware store? That's pure science fiction.

 

Now that I have a GPU powerful enough to include proper wet racing (in VR) I'll have a closer look, it's one thing I've been meaning to do for awhile.

Also it's probably best to post videos of AMS2 in action not any old YouTube real footage, then we can compare issues properly.

 

This reminds me of discussions regarding FFB-effects; people sometimes get stuck arguing about real vs fake (Canned) FFB-effects. They seem perplexed when reminded that all the FFB-effects are actually "not real".

 

Yep, I love the "it's not canned, the effects are generated by the physics engine! " argument.

 

You said "Tracks do have drainage" "natural run offs, levels" "standing water forms puddles which do not happen everywhere on a tracks surface" ... so what is the point of posting AMS2 footage when you can go ahead and test literally any track in the game and find exactly 0 standing water even if you set the weather to thunderstorm ? Real footage shows that tracks in fact do have standing water while the same exact track in AMS2 does not, that was the point of my argument.

It used to be extreme where a corner was a total lake with it being impossible to drive through but now it is the opposite extreme. And i have a suspinsion standing water was removed because people reported that everyone had different standing water on the track in different locations online, so it was easier to fix it by removing them entirely.

How was AMS2 able to make it work for years until it got removed then ?

 

You are two times wrong...

But I will like an option to have my soaked tracks back, in SP and MP. It's more fun and unpredictable.
