I wasn't dreaming, I was racing online, (perhaps overdid it on Sunday, I was sitting in front of the TV for close to 6 hours), we do street car racing at about 500pp online, and I reset the time to 4:00pm, featuring nice tall shadows scattered across the track.

We were into the zone, clean races galore, fight to the finish every time. 1 lap races. in about the 5th hour of our race, I wiped hard, resulting from clipping the sand trap with my rear tire, at 170km'hr, (Pflanzgarten) on the right hand double apex section, leading from the down hill, at the top of the track, thus having the 3 cars behind me collide into me at full speed. It was a hard hit, echoed into my newly acquired wireless headset (7.1 theater thunder impact, lol),

To make the long story short, (unfortunately, picture not provided..but I do have the replay saved, hoping I could see it again), when I raced my final lap of the day, in that same corner, I had my eyes peeled on something dark, small, round, that I swear was not a typical shadow.

and I negotiated that turn over 500 times last year, with secure grip, and wouldn't you know, just as I passed what my brain formulated to be an oil patch, (close to the right hand side of the track, away from the sand, near the right rail guard) my car slid out from it. It was so awesome. No red tires. But a rare occurance.

Can anyone confirm if I was dreaming?

Why didn't I avoid it? Perhaps I could have, part of me wanted to test it out.

p.s a new DLC VW Golf drove nose deep into that rail some races ago.
 
I would love to believe this so a picture would be good :)
 
You were probably dreaming and you saw a blocky shadow. Since you have saved the replay, that is a good thing because you haven't thrown all the evidence away.

Next time you go on Gran Turismo 5, go back into the replay, wait until you slip up, and take a photo of the oil slick on the track. Then we can confirm if it was a shadow or an actual oil slick (which I doubt because this isn't Mario Kart :lol: ) .
 
You're probably seeing the bluish-black "spot" on the track that comes with running it during time change. Usually shows up when the sun is going down. It's been there for a while.

This.

Chances are if it was an oil patch, it would of been visible at all times of the day. Maybe it was just a coincidence you lost grip driving on that spot you thought was an oil patch. And plus, think about it. Would Kaz deliberately put an oil patch there to trip you up on a race simulator? No, he wouldn't.
 
could the oil have formed from crashes at that spot a few race sessions ago? Although, I doubt the track would change from one race to the next (1 lap races)

Was it a dark purple like dark void 0.0 its a shadow glitch not an oil slick ... you can see them on le mans when you change the time to sun set.
 
^ perhaps it was an oversight, as I did fast forward the time to 4:00pm, and it happened soon after (was racing since 5:50 am sunrise) track and time. But even if a purple shadow glitch, what are the absolute rare chances, that a) I virtually never saw this on track before b) the car behaved just like passing through an oil patch (did not clip nor touch curbs at that moment)

I'l work to get the replay up here in the coming days.

I'm a replay save junkie, yet I rarely review them, I'm too busy driving. I have so many I wish to share, for instance, where a race was so tight, all ~8x of us were on the carrusel at the same time. (no not resting, lol)

others where 4x of us cross the finish in less than 1s split difference

So in conclusion, it was just a shadow glitch that you just happened to spin around on, making you think it was an oil slick :) .
 
It could be, though unlikely, that pd implemented a system where random oil patches pop up on the track very very rarely. Never seen this, so probably not.
 
If the sun was going down, the track temperature would also decrease; it does tend to suddenly drop off in a matter of minutes in the game. That might explain the lack of grip.
 
I saw a thread somewhere asking if you have more grip during daytimes in GT5 compared to night.

Daytimes = Hot Road (assuming you have nice weather) = Warmer Tyres = Better Grip

Night times = Cold Road = Colder Tyres = Less Grip <- (Since the sun was setting would explain the sudden loss of grip)

This.
It could be considered a graphical glitch.

Nothing to worry about.

Temperature variations never made it into the final release of the game.

In what sense? The map with temperatures from GT5:P? I don't remember them ("temperature variations") being officially discussed / even mentioned.

I'm pretty sure the track gets slippery at night, though. I've never validated it with laptimes, but my braking distances tend to migrate as the time of day changes - it's more noticeable on accelerated time, naturally.
The same is true of weather; the track gets slippy before it rains, once the sun has gone in - that I have seen reflected in my laptimes, on the Suzuka 1000 km.

Ugh....this is so annoying to read.

Way too much extra information I don't care about.

I did the Nurburgring 24H race and my times never dropped during night and my times were consistent throughout the whole race.

you obviously cared to read it and post about the extra information, thank you!:dunce:

sorry, need another day to get the pic and or video up. no, it's not about photoshop.

Thanks for the input. 👍
What was the weather like?

My times on the Suzuka 1000 km (the only enduro I've done so far) were "consistent" (as much as I can be) once the rain came. After the start, my times slowly decreased as I got down to my preferred fuel load, got used to the car (I went in cold) and the sun was still shining; they increased again once the sun went in (my fuel load was stable by then) and increased further when it (eventually) started raining. So, despite the grip reduction being reduced in A-Spec, overcast racing still seems to be slower than sunny racing; the weather also affects tyre heating, but only really when it's raining / wet.

I would be very surprised if this hasn't already been properly looked into; searching has thus far been fruitless. I'll try again anyway...

As far as I can recall, I've only really noticed this time-of-day-dependent grip reduction online, so maybe it's really only an online physics quirk that happens to feel like (track temperature changes giving) different grip levels. Or perhaps it might have been due to the weather, such that the time of day was only a coincidental factor. Either way, having the surface grip levels change with weather means it's trivial to have it change any other way, so it's not technically out of the question by any means.

EDIT: I did a braking distance test on the start-finish of the Nürburgring 24 hr in My Lounge. It turns out the braking distance is unaffected by time of day, or weather (so long as surface water is 0%).
Braking distances were also unaffected by "tyre temperature" (blue vs. white), and ABS (1) braking distances were matched by ABS (0) braking with the wheels locked, irrespective of brake bias. This held true for all tyre types, although I only tested three cars: Caterham Fireblade (hard to heat the tyres), Alfa 147 (very nose heavy; stops sideways as a result) and the latest Cappuccino. I would try some more heavyweight cars, but I suspect there'll be no difference; downforce is also an unknown at this point.

Now, I suppose that the "feeling" of having less grip when running on cold tyres is also something I'm imagining; or braking tests are not the best way to test grip levels, or the online physics really are simplified...
