Hey guys,
It would be great if pro drivers could help me a bit to check the LiveTrack sync.
The race around Zolder is the perfect example to check this out.

@S4Howie ,@Nagrom , could you upload your race and share it there please ?
I'll do the same for my race :)

Here is @borates 's race :


@ShaggyDan :

@DaWu :

@Nagrom :

@Marvin

----------------------------------------------------------------------------
I'll edit this with our findings.

My findings so far :

In my race, The first time I saw rain droplets on the video is around the 40:56 mark, before the 2nd chicane.
On @borates 's video, it's hard to see it but I'm guessing some rain drops around 40:36, before the 2nd chicane.
It's very hard to see though, because of the compression. Can you confirm this?

Well, It's too hard to see because of the youtube compression so, I'll take screenshots of the rain, it would be great if some of you could do the same, to be able to compare :)

It's raining more and more :

As it's still raining, I adjust my pit stop strategy :

It's barely visible here, but I had very small droplets here. My laptimes are still good / decreasing.

I'm starting to slide a bit and the back of the track is getting harder to negociate.
The track is getting darker with some very small puddles forming. I asked for the pitstop.

I didn't go for the stop but I'm starting to slide quite a lot even if the rain is not that strong :

Heavy rain there, decent delta time :

Laptime is starting to increase quite a lot. I'm understeering badly, I went for the pitstop. That was maybe a bit too soon.

Im on wets. I'm hearing water noise

I'll upload my video soon, but I think it's worth mentioning: Pcars 2 "simulates" clouds, so when it begins to rain, it's raining only on one part of the track, and if the could moves, it can change as well. So at the same moment, someone may see some rain drops, and another person don't because he's not at the same place on the track.

Honestly, it's not worth uploading, I can see nothing on @borates video.
The best would be pictures directly from your recording.

And yeah you're right. The time is not the same, but the place should be, approximately the same.
So, I think I saw rain drops in borates's video 20s later than me but on the same place. (He was 20s behind me)

Another thing would be to evaluate the state of the track... that should be more tricky ^^

@Scott made the fastest lap at 37:12.
The rain already started to fall on some places for me but my delta was still green too because of the temperature fall.

It's not about the Zolder race, but at the last race of the Endurance League the puddles were not synced: https://apexonlineracing.com/community/threads/aor-endurance-league-season-3-r5-daytona.32096/page-7

Ignore my previous post. The person from the first photo was kind enough to share the footage from the last 30 minutes of his race, and he did have a puddle at the busstop chicane.
I'm not sure why it was brought up on the AOR forums that he was driving around without a puddle at said location.
Now that I look at the photo I can even see the puddle. It's probably less visible due to graphics settings.

I should've reviewed it more thoroughly before I posted it here, I apologize.

No problem mate.
It will be a quite long term task anyway as it's sooo time consuming and I have other stuff to do.
