I think for me it's more the online racing rating element, for that price I'm willing to see if they can do better than PCARS2.
Still, kudos to the makers of the rain mod for AC!Still, there’s more. ACC now simulates variable dynamic weather and so we have…
Rain.
Rain in ACC is not simulated by simply lowering the grip. We simulate mathematically an actual water film depth. Tyres go over it and depending on tread design, load, speed and more, they manage to drain the water out and have a contact with the ground… or not. If the tyre can’t drain enough water, then it starts losing contact, up to complete aquaplaning, which means total loss of grip, zero, null, nada. So in ACC the feeling you get from a wet circuit is a good grip but a constant feeling of “something is about to happen”. You might do a turn in a specific way and feel there’s more than enough grip, you might even think “hey that was easy after all, arcade™!”, only to push a tiny bit more the lap after, or have the rain fall harder 3 laps later and go completely aquaplaning sliding out of the corner. The wetness also lowers drastically the heat generated by the surface layer of the tyre, so temperature of the tyres will go down inevitably.
Slicks can go into aquaplaning very VERY easy. I strongly suggest that you watch the first laps of the Hungaroring race1 of the Blancpain GT Series to understand how cars on slick struggle on damp conditions, but also how the BMW M6 that had wet tyres could work his way from 11th position to 2nd and struggle right afterwards when the dry line started to form. You can also see him searching for wet spots to cool down the wet tyres. Here's the video. Race starts in 33:00
Also in ACC wet tyres will overheat dramatically in dry conditions and you can cool them down going outside the dry line, searching for wet spots. Beware that in such conditions it’s easy to place one side of a car in the wet spot or puddle, resulting in high rolling resistance force from the water depth (and sudden aquaplaning) that can easily destabilze your car.
I will also mention the obvious…there is no way you can stay on the track under heavy rain on slick tyres. We’re not talking being slow or having difficulties to control the car… we’re talking complete and utter loss of control and sliding around on “ice”. Fear not though, for people that want to experience the graphical majesty of rain conditions but in a less hardcore grip situation, we have a nice option slider that will lower the amount of physics water… just for fun.
Staying on the dynamic track subject, here’s how a track surface changes through different conditions.
Obviously this is a generic description of how the whole system works: in reality and when the whole thing will be finalized, your experience might vary a lot and can become more unpredictable. The whole idea behind it, is to have deal with unpredictable conditions that will force you to adapt.
- A green track will get gradually rubbered. marbles can appear at the side of the rubbered line
- If rain starts then (depending on the force) it will wet the track and the rubbered line will start to be very slippery. You might be forced to avoid it or explore alternative lines.
- If rain keeps on pouring heavy enough, it will clean the rubbered line and you might be able to turn back to a more traditional racing line. When this happens? I don’t know, try, experiment and find out!
- If rain keeps on going, puddles and “rivers” might start forming. Those also might force you to try different lines again. Puddles and rivers are placed in specific realistic places on the circuits, derived from actual drivers feedback and their onboard videos.
- If rain is lighter or stops and many cars are lapping, a dry line might form or simply a “less wet” line. You will obviously have more grip over the dry line but wet tyres will overheat.
- Finally puddles will be the last to dry out, so watch out even if the track is slightly damp and slick tyres are faster, puddles can still catch you out.
Special guest…
Marbles.
Did you know that real drivers will go over the marbles to collect them on their slick tyres so that they gain a kind of “tread” which lowers a tiny bit the risk of aquaplaning? Of course you’ll have to deal with less grip and vibrations, but nothing is worse than aquaplaning and it might help you until you go in for your pitstop… or the rain might go away and you’re ******… ops!
Then we have tyre damage
An inspired choice indeed! The timing with the sunrise was epic.
