SlipStream effect

Well, since I use the 2006 Mod, I am playing with the slipstream effect option
of GP4 tweaker. It was an option I never used before.

There are 3 differents parameters. by default the first one is set to 50 for all cars and all tracks, the same for the second and 3 for the third one.

Are some of you are playing around these values ?
Did you changed it or let it to default ?

what are your new values if you changed it ?

hmmm a lot of question no ???

Heheheehe. Hope you will can help me to work on this tweak, and to get
a game more realistic.

I haven't touched any GP4 editors in a bit, but I believe the last one is to simulate 2005 physics, with much less slipstream in the game

The last is to follow 05 regs, which increases revs, gives understeer, but no extra speed.

In the released 2006 mod beta... it is turned on? I couldnt feel any difference, well, maybe because I'm always on the lead :P

Set the first and second values to 20, 25 or 30 and you will stay closer to the car ahead in fast corners.
50 is far too much for me - at fast corners and tracks I have no chance to overtake because I lose so much grip, get extreme understeering.
Of course this dirty air is realistic, but imo to extreme. Hence I have set it to 20, the effect is still there, it's not easy to overtake but it is still possible.

so how do you this effect?

Thanks Martin.
You are right. 20 is surely the best value.
Don't know if it's realistic (Never drive a F1 lol) but at least the effect
is active, you can feel the difference, and the game still "playable".
With 50 in Barcelona , it 's absolutely impossible to be close the car in front of you in the last curve without get incredible understeer...

SO 20 is the value I will use.

hmmmm, it seems this tweak is not really used or knew by gamers.....

I use 50 and it's indeed quite impossible to follow the car infront in fast corners but I like challenges and we saw that in Istanbul Michael had huge problems to stay close to Fernando in turn 8 that is fast corner .I have used this tweak since it was in beta stage and have enjoyed it very much ....without it gp4 is too easy

so can some one sum up please? talk slowly and clearly.

[SLIPSTREAM_GRIPS_FRONT]
[SLIPSTREAM_GRIPS_REAR]
[SLIPSTREAM_GRIPS_DRAG]

theres 3 values and by default they are all 50,50,03
and incresing/decreasing makes it easier/harder to follow?

I dont remember very well how they affect anymore ...Madman once told how each values affect but it was when his gp4tweaker forum was working but it doesnt exist anymore

this is from madmans original notes:

; Slipstream emulation development Notes:
; ---------------------------------------------------------------------------
; Emulating slipstream effect that work when driving behind other car's tail.
; The emulation using three sections containing adjustable data available for
; separated circuits and cars. Each section containing 17 lines of key pair,
; where each line represent an array of 22 item members for each car. This
; gives you full custom values that will emulating different slipstream
; effect for any circuits as well as any cars. Different set of values for
; circuit will gives different effects based on humidity, air pressure,
; avarage temperature, etc. Different set of values for cars will gives
; different aerodynamic behaviors for specific cars when traveling through
; slipstream trail area.
;
; Three sections of value definition used to represent coefficient value of
; aerodynamic drag and grip for specific car within slipstream area. All
; these values are in percentage and ranged from 0-100. Any values beyond
; this range or zero will fall back to default GP4 behavior. Values with
; smallest percentage (1 percent) gives you smallest results to slipstream
; effect. As a guide, setting the value to 100 percent is based from the
; highest speed in closest distance. This mean, even you set the value to
; 100 percent, you will notice none or less differences if the front car
; traveling in low speed or far from your distance.
;
; Three types of drag values are defined; drag produce by front wing, rear
; rear wing, and overall aerodynamic calculation. Please note all values
; defined here are should not assumed to produce realistic effects. They
; only represent set of "noticeable" slipstream effects. You'll need to
; reduce these values to get better or realistic effects when your car
; traveling inside slipstream trail area. Be careful to adjust front and
; rear drag. Value differences greater than 10 percent may causing your car
; to spin or unstable especially in high speed, depend on current car's
; aerodynamic setups.
;
; Slipstream area working about 1-10 meters behind a car which depending to
; car speed and distance. higher the speed will produce bigger area. The
; effect of traveling inside slipstream area will be noticeable by loosing
; of grip, understeer, higher RPM without increasing significant speed at
; straight line, etc. The effects also noticeable when you are using force
; feedback controller.
;
; Notes:
; This is a revision version from the original which has a small "bug" on
; font and rear calculation. This fix also improving math codes used to
; calculating slipstream areas based on front car's distance and speed. The
; values now also using positive percentage (it always ranged from 0-100).
-----------------------------------------------------------------------------

[SLIPSTREAM_GRIPS_FRONT] from what i know, this determines the amount of grip the front end has, but the numbers are reversed. i.e 100% grip is 0 and 0% is 100, it can also be interpreted as understeer, at 0 you obviously get no understeer and at 100 you can't turn in, a value from 20-30 would be most realistic.

[SLIPSTREAM_GRIPS_REAR] i think this determines how dirty the air will be when it leaves the rear wing, so if you set it to 40 and the value for grip_front is 30 you'll notice more understeer, what i try to do is to get the values of the front and rear as near as possible, but if you wonder why they aren't the same, its beause i remember montoya and button once saying that following the ferrari was so hard, but other cars were produed less dirty air.

[SLIPSTREAM_GRIPS_DRAG] is basically the calculation of the effect but i'm not too sure. i.e its the default slipstream effect times (X) 0.3 so if you add extra values to the front and rear then change the calculation to 5 it would add the values then times it by 5, but this is just speculation, i haven't tweaked the data for a while.

hope this help

Where is this option in Gp4 tweaker? I can't find it.

Thanks for any help.

Mwb.

I'm having some troubles configuring this slipstream effect. I mean, I think i've intalled correctly but anyway it seems not be working, the CC cars can overtake quite easly in Barcelona track getting quite close to the one in front...?
The installable comes without any explanation. PLease, help...
Thanks

@vesuvius: What are the three values you have set?....50, 50, 03?...Or something else?

@Ali
More the values discussed before, there are also two options
in the main tweaker.ini
(Don't remember exactly the name of the file.ini and I am not at home....)

The first one switch ON/OFF this effect.
The second enable this effect ONLY for player car. With this option set to 1
cc car are not affected by Sliptream effect.

Could be a reply to your question

Hey guys,

I searched, but I can't find the option in GP4Tweaker. Where can I find it? Please help me, it would be great if I can use this option.

THX,

yea.. where can i find the option???

Thanks!

I found it... I think you need, the newest version. I think it's 1.0.4.5 Reloaded. There you have an .ini file where you can activate it and in the SlipStream.ini you can choose how strong it should be. It is an great feature!
