I hate the rain too, though I do in all racing games. My second real life wreck was in the rain, and I got pummeled by the first gen airbag in my parent's car, which they loaned me to get to work. That was a humbling ride home, but they were just glad I wasn't hurt. Much, that airbag was brutal at only 30mph.

Still, the rain dynamics and tires both need some attention in a future physics update.

I do too. Seemed that plenty of people were getting excited about rain buildup to tge realease (guess its realistic in the sense they do race in rain irl) but I just hoped it wouldn't appear that often. It's a a pain in the arse

On console, you have it in ACC, PC1, and PC2.

On PC add-in RF2, AMS2, iRacing and most likely a few I've forgotten.

iRacing has wet weather? I thought that was still being developed. Or did I misunderstand what you're talking about?

I belive it's gone in as a beta, not a regular iRacing player myself.

Wet weather physics suck. AI seems to have no influence from the wet weather while I suddenly have zero grip on the softest available tires I am allowed to run.

Thanks to everyone telling me to run wets or inters, I NEVER would have thought of that on my own.
The events I am talking about are the ones where you are restricted to Sport tires only so you can’t run inters or wets.

Running any compound sports is still pretty manageable IMO. Just need to pay attention to the surface wetness bar that's in the bottom left corner of the HUD. Between that and the weather radar it's made me enjoy the challenge of wet racing finally.

 

[barak181]

They have a definite advantage under acceleration from what I've observed.

They also behave unrealistically during the transition phases from dry to wet and then again back to dry. It's like a switch they just flick from being fast to slow or from slow to fast.

I'll gradually change my pace as the track surface evolves, but they just suddenly go back to driving at dry weather pace instantly. It's ridiculous and it makes me not want to race in random weather conditions with the AI.

Most wet weather races have a time multiplier - just like there's usually a tire or fuel multiplier - so the transition from dry to wet and back again is artificially fast but that's by design.

It's not true. I won a lot of wet tracks, and I saw that AI can't drive in storm at all. I race was in Le Mans, there was havy rain. I lost my car twice and went to pit-stop in 70-80km speed for 1 minute, and AI behind me was even slower then me!
And Fuji wt800 rainy event is also the same. AI is really slow here all the race.

Oh, we know.

Anyway, a new member with a question does not automatically make a troll. Read the question and if you do not wish to help, move on.

What event is it ? Do you have the choice of the car ?

I find the IA quite bad in the rain actually, and I am not a good driver.

Sport tyres works well in heavy rain tracks. Simply, you never should go to full gas, always medium throttle or less. You go faster than 100% throttle, even on straights

 

[UnkaD]

Work on your technique. When it starts raining mid-race I know I'm about to best them in spectacular fashion.

And I know I'll be much faster than them as well, but not until it's sufficiently wet and we've all changed tires. Until then, I have to manage not losing too much time. And if it stays wet until the end, the there's no problem at all. I will lap MUCH faster than the AI, but I do notice that they will still accelerate out of corners faster than I possibly could with the grip available.

On the other hand, if the rain stops and the track dries then all the time I gained will start to disappear no matter how well I drive, full wets or inters. The rain does affect the AI, it's true, but I don't believe for a second that it's not artificial and if they wanted they could drive perfectly fine on slicks across a lake.

Most wet weather races have a time multiplier - just like there's usually a tire or fuel multiplier - so the transition from dry to wet and back again is artificially fast but that's by design.

And I transition my pace to match it. I know how quicy it changes. But for them there is no transition. It is instant. They will drive just as fast right up to a certain point and suddenly slow down. After it's done raining their pace increase is just as sudden, and more of a hastle to try to deal with. They can lap way quicker on inters while it's drying than I can.


I'm not complaining at all about the rain and variable weather. I absolutely love it! At the same time I observe where it falls short in how the AI behaves during offline races.

While it would be easy to deal with if you know exactly when the rain will come and how long it will last, you have to run the race first and decide if the timing is beneficial to you or to the AI, if the AI happens to be faster or slower in that race, and if you want to back out and shuffle these conditions until they suit you. Keep retrying until it all lines up perfectly and you get to run down that 40 second gap to the leader, thanks to chase-the-rabbit.

This is something I do once and forget. I wouldn't mind so much with a grid start, but the amount of time you have to make up is too much to stomach with so many variables to make it fun. I've had this feeling playing through the game that so many events is just a big huge dice roll whether you will win or not. Just like that Daytona race, where I just had to keep leaving and trying again until the leader decided to pit twice instead of once.

I'd love to try online races with random weather once I'm not worrying about making credits anymore!

 

[Islaygaz]

A proper weather map or forcast would be great before the race instead of starting a race then backing out and restarting.An option to buy wets at the track would be better.

Or an even better option would be you can buy racing tyres in GT Auto that gives you all 5 compounds instead of having to buy them individually. I can’t imagine racing teams are buying separate compounds in real life!

The events I am talking about are the ones where you are restricted to Sport tires only so you can’t run inters or wets.

The races where you can't change tires shouldn't be hit with heavy raid, so it's more about tiptoeing around the track, keeping the dry line and put a egg between the fingers and the controller.

Helps a lot, if you have the choice.

 

[Pizzicato1985]

It's definitely realistic. I appreciate the challenge personally.

At times it can feel realistic, many other times it feels way overtuned, just like the RWD oversteer.
When it actually feels realistic it's great, love a fair challenge. But sliding off the track on a slow corner at 20mph... nah, lol. In ice, yeah, I've had it happen plenty of times irl, but not in the rain.

I still think there's something off in the traction calculation, and hopefully it's as small as changing a number in the .ini (or PS analogue file) so that it is easily fixed by PD

 

[Sven Jurgens]

Lol, maybe try some wet weather tires? The AI isn't cheating they just know how to drive in the wet.

They are definitely cheating. They drive on normally until the rain gauge reaches 2 segments while you struggle to stay on the track until you can pit. Yet when the gauge reaches 2 segments, the AI slows down to 90 kph and drives in a procession until they can pit.

The AI is much faster than you can be on rain tires, but sticks to a certain speed limit on straights, easy to pass as long as you keep track of aquaplaning. (Blue on the rain gauge). On intermediates you can go up to 210-220 kph with 2 full segments, on heavy wets you can go full speed unless the blue gets too big on the rain gauge.

A drying track is the most dangerous. The AI will switch back to normal tires asap and has very little issues with the still wet segments. You can choose to stay on intermediates, which burn up rather quickly on the dry line. Or you can risk to switch back to normal tires, yet when you hit a still wet spot it's basically like touching black ice. All grip instantly gone.

I race a lot on N24 with rain. The dry line is pretty much bone dry within a lap after it stops raining, it takes 2 more laps for the rest of the track to dry out. I stick to intermediates for an extra lap and drive over the wet spots as much as possible to conserve the tires before switching back to normal tires.

The start/finish straight is the most extreme. Bone dry on the right, 2 segments and easy spin out on the left on intermediates.

I love the challenge, but it's a bit annoying the AI drives by completely different physics in the rain. They do spin out quite a bit which equalizes the speed difference!

Here's an example of aquaplaning on intermediates. I hit 220kph while the rain gauge hits 2 segments, game over

Stay below 220 and that little blue bit won't kill you, or use heavy wets. Yet if the blue gets bigger, slow down.

On Heavy wets, no problem

Going close to 300kph at 11 minute mark with a sliver of blue on the rain gauge

Your tires seem pretty worn. Would that have any effect?

I don't know how these tires work, but the performance seems to drop off pretty badly for me once they go below about 1/3 red. I don't know if that affects aquaplaning, but the car definitely seems easier to spin.

It doesn't affect aquaplaning, but does make the car harder to corner. I switched to intermediates early there and they burn up really fast when the track is still dry.

Something feels up with tire wear as well. When I use RH I can do 15 laps on N24 without any significant wear (x3 tire wear) yet on mediums the 5th lap is already a struggle. The AI always uses softs and don't really seem to be affected by tire wear. I can do 3 laps at most of softs on N24 at x3. Not worth it with the long pit times when only the first 2 laps have benefit.

Tire wear with intermediates and wets is extreme when the track is still dry or back to dry. When it's wet they degrade as slowly as RH.

In custom endurance races time acceleration doesn't seem to affect track drying speed, but it does affect how fast the weather moves on the radar. At x2 you have about 25 minutes to prepare when rain shows up on the edge (max zoomed out), x3 16 minutes, x8 less than a lap on N24 and you risk getting caught out.

Edit: It's not time acceleration that changes the speed at which weather moves on the radar. It's the length of the race. Custom weather maxes out at 9 states from 1 to 24 hours endurance. Each state gets longer and weather moves more slowly accordingly. Normally I adjust time acceleration to make it a full day night cycle, 3 hours x8, 4 hours x6, now I'm doing a 2 hour race at x2 and got caught out on the track as the weather was moving in faster than a lap on N24.

Worn tires should and probably do effect aquaplaning.

Does the wet weather tires last longer if you cool them down on straight?

 

[Sven Jurgens]

It helps a bit, also staying off the dry line through corners where possible. Brake on the wet part in the braking zones. Worn intermediates are still safer and easier to control than hitting a wet spot on slicks. Beware of the pit exit lane, stays wet the longest.

@Magog Dunno, the speed 'limit' seems the same, worn or not, but it is much easier to recover when you start sliding or hit a puddle on the track.

I haven't experienced such extreme aquaplaning in those games. I have aquaplaned over puddles in those games but I've never had an occasion where the car just broke lose without warning.

I've not tried them all back to back with the same car yet, but I do recall a lot of people complaining about it in both PC1 and PC2.

I think I'm going to have to try them all with the same car and track combo and as wet as I can get it.

Well let me tell you, it's easier to drive the Sauber C9 in the wet in Project Cars 2 than GT7.

Personally, I like the wet conditions.

 

[Uday9479]

Yesterday was in a Gr3 race at Suzuka under the Menu book race to acquire a Supra in RH tires.

I did manage to overtake all the cars by lap 4. Guess what it starts raining on lap 4. I've noticed the 1st lap or so it's fine when raining but then all hell breaks loose!!!!!!!!!

All the grip just goes away & literally any corner You can aquaplane. While the AI as always is on rails, their speed slows down but they've got great traction & cornering speed whereas I keep going in kitty litter. Even if I increase the TCS to 3, I just struggled.

Since this was a 5 lap race, how could I pit? Would be dead last as well. But by the middle of the 5th lap when I was struggling whilst AI was having a good time, I exited the race. Too frustrating.........

 

[Chris30]

Yeah I don't do very many wet races either but I have to do them in the campaign mode, Championships otherwise I can't progress forward.

 

[rb26dettNUR]

I don't like to ride in the rain because it's cool, I ride in the rain because I like to ride.

Besides that, I don't ride in the rain at all.
