the same deal as RBE issue in professional mode... PD is looking for "The real driving simulator" or not!? :sly:

Yeah but my point is that even if proper fluid dynamic simulation of slipstream is too complex for them to pull off it's no reason they can bodge it in the meantime. I'm sure some peeps will complain it aint "real" but for me a step in the right direction is better than no step at all.

Lets face it - compared to comedy draft in prologue, turning it off completely would be a step in the right direction :sly:
 
There could be simplified predefined maps of air stream areas behind the car depending on car shape and car speed, very easy job for PS3.
 
Instead of taking notes of arcade racers like FM3, they should be taking notes of excellent simulators like NASCAR 2003.

I remember racing the 24 hours of lemans using a sports car and track mod for the sim.

Coming out of the final mulsanne chicane for a few laps in a row about 50 yads behind the driver in front I was only able to get a tow of 2 or 3 mph, nothing enough to really pressure him. Then after a few laps I came out of the final mulsanne chicane about 20 yards behind, I got a big tow worth about 6mph and I was able to pressure him, but he blocked me (real driver, not AI), and I backed off. Now if we were dealing with GT's draft we would be swapping positions every straightaway. This would be exciting but not challenging or more importantly realistic.

rFactor's draft takes into account the shape of the vehicles.

With GT5P the only way to increase the speeds of two cars running nose to tail around Daytona is to bump draft. In real life this is not necessary, as two cars running nose to tail will automatically go faster.

in NASCAR races will be a toyland as the effect is at the moment...
 
Great thread, I posted some stuff in another thread that really should be in this thread instead.

That video is quite interesting, the GT5 slipstream is actually even worse than shown in the video for a few reasons. The F1 cars are going much much faster, yet they STILL have less slipstream effect than the GT5 cars. Add to that, F1 cars have a much higher hp/weight ratio (think motorcycle as an extreme case) The F1 cars are basically topped out very early in the video, they are at terminal speed before reaching the final banked turn, and almost all of their available power is going to over come drag, which again means slipstream should have more of effect for them compared to the GT5 cars, yet the GT5 cars are STILL more effected...
Anyone have an email address for PD?

I have to agree that eliminating the slipstream would be far more realistic than what prologue has now. Prologue is follow the leader until the next straight, it doesn't matter how you drive if you are following someone, and winning a race is just a matter of being in 2nd place on the last straight. Its even worse if you are last in a pack of 3 or more cars, you simply can not pass, no matter how much better you do things than those in front of you, because its game over when you pull out to pass its game over...

On a related note I actually had a very exciting online race last night with one of the top guys from JP at Suzuka, he was not nearly close enough to draft but we were almost matching sector for sector, lap after lap- it was like real racing you read about, after 5 laps I pulled only like 3.5 seconds on him, great fun- all because I started far enough ahead that the drafting didn't come into play

who don't want it!? :D maybe our "inside member" amar212 has it... 💡

my concern is that even GT5 Demo (which is the last version we know) brought that effect just like prologue... and we are close to the game release.. :nervous: however there's a little hope due what happened in Irish GTAcademy finals...

@ 370Z vs. f1 video, you can't really compare the two since the 370z will produce a stronger slipstream than an F1 car since it's just bigger. Although I do think PD needs to reduce it as it does seem a little to strong.

Actually my guess would be that the F1 cars have a bigger/stronger slipstream because of the massive downforce they produce. I dont know for sure ;) but that's my semi-educated guess.

Yeah, a true aerodynamic simulation of the fluid forces wouldn't be possible. Even on modern super computers it can take several hours to simulate just a few seconds worth of fluid flow. On a regular desktop machine it can easily take days to solve a few seconds worth of fluid flow over even a simplified shape.
 
PD will only change if we complain a lot. This is an issue since the first GT, so they had plenty of time to see that it was absurd.

Like the downloadable GT HD thing, we need to voice our opinion and hope that someone at PD is reading.

It isn't even up for debate. The slipstream on GT5 Prologue and on the Academy finals is so wrong it looks like a joke.

It allows for bad drivers to hang close to the leader.

It doesn't reward the best drivers.

It provides stupid finishes like it did in one the academy finals were the slower driver slipstreamed the leader on daytona for two laps only to pass him on the last straight (wouldn't have happened in real life, you can judge by yourself watching the video).

Like the sound levels, slipestream effect MUST have a slider where you can choose from 0 to 100. Game sliders, like the ones that became a norm on sports games.

I agree. It completely screws with the tactics and skill necessary to win, especially at tracks like Fuji, DR and many others to a lesser extent :ouch:

With the slipstream the way it is, IF you want to win the race it's basically as simple as waiting behind the leader for the entire race and then making the move once you exit the last corner (Fuji & DR). This completely screws up the tactical realism necessary to be a truly great racer in real life, where making a pass isn't as simple as relying on a ridiculous slip stream to make an easy pass for the win, or to keep up with the car ahead to begin with.

PD definitely needs to get rid of this Arcadish crap, as it really has a large negative impact on the realism/credibility of the online racing side of the game. Luckily I have a feeling that we will at least be able to turn it on/off in GT5, as well as having the possibility of being able to adjust the level of slip stream as you mentioned...

turning it off wouldnt help to have better races either... because slipstream is still needed at high level racing otherwise we wont overtake each others...

unfortunately that happened in the GT Academy final... to deal with that people need to adapt their tactics to the game failures.. and thats BS...

can anyone image a NASCAR race with this sliptream!? :sick: :indiff: :yuck:

how the hell do we reach PD about this!?!!! they've heard our RBE complaints and they fixed it.. and slipstream is so important in racing matters but also easy to fix i'm sure

Excuse my ignorance, what is RBE?
 
it means: "rubber band effect"

its like a kind of boost for the last cars in the race to catch the leaders more easily...... (and put them out of track most of times, not anymore thoguh, they removed it in PRO mode)


GT5 is almost "The real driving simulator" :dopey: :ouch:

Sorry I didn't word that very well :dunce: I meant being able to "turn off" the EXAGGERATED slip stream effect, so you would be left with a realistic representation of a REAL LIFE slip stream (which varies from car to car of course).

I definitely agree that there should at the very least be a REALISTIC amount of slip stream, but definitely not an exaggerated slip stream like we currently are stuck with :yuck: , unless it is an OPTION which the player can enable for their particular room/race.
 
I haven't read the whole thread, but wasn't the slipstream toned way down in the Irish GT Academy Finals? They did have an unstable new code version there....

It does seem most of the code used in the other countries had traces of Prologue in there
 
having an adjustable slipstream would be less realistic than having an exaggerated one. Slipstream isn't something you change with the turn of a knob like music. They need to tone it down and that's all there is to it.

can any one actually prove this? Someone that was attending the event mentioned it but that is far from proof.
 
Let's say real racing is 50, off is 0, and GT5 Prologue is at 100. If we could tweak between those settings, then i would be happy.

I don't want to turn off, just to adjust.
 
adjusting physics, or whatever slipstream fits under, seems very arcade to me. Don't bring up normal/pro physics cause to me that is just adjusting difficulty more than anything.

who said it for the 1st time was Warren(theewar).. which is a very reliable person with thousands of hours at least in GT5P... but there were more guys saying it from the Irish final...

Great news if true!! 👍
 
Best news in the last couple of days! This is actually gameplay related, so i´m glad they listened to us!

Once again, complaining, when it´s fair, it´s a good thing.

It´s great that the text indicates a possible slider.

We might need that to simulate proper draft for different types of series.

Drafting is completely different from a F1 to a Nascar car. Hopefully the slider will help balance those differences. 👍

IDK to me it seems like it has been fixed. From all of the NASCAR videos I have seen none of them have a crazy slipstream effect. For example on alba's latest one he did not pass anybody with a crazy amount of speed and neither did the AI. I am pretty confident that it isn't bad at all this time around.

Ok after rewatching it I did see quite a bit of of slipstream
 
Happy to see its been tweaked.

Hopefully it will be as advanced as rFactor's, which takes into account vehicle dimensions when calculating the effect
