Was chatting last night about all things PCars and it came up about flat spotting, drying line and track marbling, none of these I have actually seen, has anyone actually experienced any of these I mean in AMS if you got a bad flat spot the wheel would go crazy and shake, you definitely knew you had a flat spot.

Also with longer races we have done with rain when the weather transitions to dry back to wet the track does dry but not on the racing line I would expect to see wheel tracks of the dry line, same with the marbling the outside of the track should be littered with rubber but I don't see it?

Anyone got any thoughts?

Drying line... Some tracks seem to show it better than others:

Flat-spotting is heat related only. That was a decision SMS made as their model does support it (and it was in the WMD builds at one time).

That's hardly really visible and the track looks fairly dry looks more like a rubbered line, I was thinking more like this in F1 2017.

I have never seen the marbles though, think someone did a test and the track looked the same after quite a few laps of an oval?

Looks cool, but that's not how it really works.

I don't believe there is dynamic marble build up since PC2 allows very long races (and it would be a performance issue).

Well this video clearly shows the drying line on Brands and it looks a lot like F1 2017 but I never see it that prominently, also talks about dirt and debris getting pulled on track but I don't see that either?

Maybe I'm off track more than you, but I definitely see sand on the track after I or an AI car rejoins track after a quick picnic on the beach. This is offline btw. Drying line also clearly visible offline, but I've heard that it rarely shows online.

Interesting, I have never done any offline races, it definitely doesn't show for me online.

The dirt and debris happen but the graphic effect isn't shown much (performance reasons). The physics underneath have it. It did show a lot during pre-release but it was toned down.

The drying line depends on the race length. The Brands Hatch photo I showed went through the same transition you see in the video. I just took the photo at the point where it's easiest to see. Some tracks it's easier to see and others the track surface color it's very hard to see. Sugo is another where you can see it decently.

Long Beach was another were you can see it (and with Long Beach, you have the little puddles still off the sides at places).

In short, yes there is a "dynamic" drying line.

Again that track looks nearly dry if not already dry, when you watch real life races in heavy rain the cars wet tyres disperse that much water that it literally sucks the line dry, I see it in my daily driving in my own car, it is just not very clear if at all that it happens and if it does it should be clear on every wet track shouldn't it not a select few where it is faintly visible.

We did a long race on Sakitto where there were puddles formed and when I was on someones bumper I would expect them to 'plough' the puddle creating less of a puddle for me right behind them but the puddle is just as deep, the water flies up but does not disperse?

This is a pic I took with my phone, light rain then clear. Again, offline. 260854

Hmmm.. I'm not sure what you are getting at.... There are stages in the drying line when the sides of the track are wetter than my photos, but the what I've experienced in real life is more like the videos here...

Marbling - I’ve seen visual evidence of it but it doesn’t affect the car at all. Driving on the marbles, especially longer into a race, should make for horrific cornering so appears visual only (and not very visual at that).

Flat spotting similarly in that it’s not felt through the wheel not appears to affect the car in any way other than a slightly more worn tyre.

Both aspects appear superficial only, which is a shame. The affect of both marbling and flatspots was significant in AMS so definitely an area in PCars2 that was a step backwards for me.

Yeah, flat spotting was quite prominent in PC1 too, from what I remember. Shame it appears to have been dialled down to non-existence in PC2.
I haven't done much wet racing, but when the demo was released (which was using an updated version, compared to the full game) I tried it to see what the fuss was about and instantly noticed a drying line on the RBR race. Offline of course.
I can't say I have noticed anything similar to that since, it was quite prominent, but that may just be my lack of attention. I should do more wet races, I guess.

The drying line is definitely there offline (I do all my racing offline). In fact the wet parts of the track on the straights I think can be used to keep the wet tyres cool but someone might need to fact check me on that to make sure its not a placebo effect.

Drying line. Set a long enough race, overcast with a slot of rain, cool track. Pretty obvious at Daytona road.

Dry line is also quite obvious in a longer race, when rain starts but driving slicks is still faster for some time... as long as you stay on the dry line! This also happened in one online league race, when rain started towards the end of the race. Staying on slicks and driving slowly on the dry line was faster than pitting for some drivers, which resulted in unexpected results. At that race I stayed on slicks too, but in the end spun out quite badly a few times when sliding off from the racing line, not worth it :D
