GP4 physics for 2009 season [RELEASED Ver.1.1 - 28 Apr 09, download link at pg.2]

i have a certain feeling that mr crammond made up some "interesting physics"

---

used to be GPGSL's Nick Heidfeld

Version 1.0 of GP4 physics & torques for 2009 season is finished and released.

The *.rar archive contains two physics sub-versions:
- one with "Soft" tires to be used at tracks that Bridgestone brings the "Soft" and the "Hard" tires.
- one with "Super Soft" tires to be used at tracks that Bridgestone brings the "Super Soft" and the "Medium" tires.

You will also find:
- a small tutorial on how to make the necessary adjustments in each track's magic datas, to have real top speeds and lap times.
- some advise on initial setup values to make easier setting up your own car when you use my physics.

Here's the download link:

3 Jan 2010 - edit: link of ver.1.0 removed due to release of ver.2.0.
Get the files from my signature or from these links:
- GP4 2009 Physics & Torques - version 2.0
- GP4 2009 Generic Performance - 804bhp

Enjoy it !!!

excellent, thanks!

EDIT: btw, does it matter which performance file we use? if so, is the one included with your provisional release ok?

I have to say that I never released any "performance" file of this format:

What I suggest for better results when using my 2009 physics is to:

- Update your GP4.exe file with the torques file included in the release 1.0.
- In the performance file (like the above) that you use, set: "Performace=785,785,..." for the top teams and use a little bit lower values for the other teams.

If you want closer times from the 1st to the last driver (like it happens in 2009 compared with the previous years) set all teams to 785,785 and adjust only the drivers' performance parameters.

New Version 1.1 RELEASED

CHANGES
New physics files – ver.1.1.

BUG FIX: Physics files – ver.1.0 when being used with performance files, make the car reach lower top speeds than expected and consequently make longer lap times.

New physics files – ver.1.1 are fully compatible with “performance” files (*.txt) of 785bhp Engine Power, loaded with GPxPatch > GPxSet tab.

Physic Files changes, compared to those of ver.1.0:
- Less Air Drag
- A little more downforce.
- A little more tyre grip.

Available for DOWNLOAD here:
[files.filefront.com]
Enjoy it !!!

Great work thanks

Hi Cyberacer and the GP4 Community,

I am new to GP4. The only F1 game I have ever played is was an old one on the N64. There is a HUGE difference! When I first started out on GP4 I would spin out at ever corner, Then I downloaded version 1.0 of your physics and read about car setup in game and finally I got a 1:34:271 at Sepang after 4 weeks! Now that I am getting the hang of a realistic F1 car I have a few Questions and I thought this was the best thread to post at first since they are directly related to the Physics.

I seem to always get taken out by other racers despite my good times. They seem to ignore me. Most of the time its because I brake to early but when I brake at the same time they do I either miss the corner completely or lose the back wheel grip. I have tried many brake ratios from 64 in the front to 54 in the front but the AI seems exempt from some rules of physics. They never hit each other but they always hit me :D. I have my gear ratio's set up perfectly for Sepang for use with 7th gear but the AI uses 6th gear and really long ratios despite the performance file saying to use 7. Am I doing something wrong? Another thing is the gas pedal always seems to be down at 1% wen my foots of the gas, which bugs me when my pit crew messes up and I have to brake to avoid a car or if I spin out the car wont stay still unless I'm in Neutral gear or my foots on the brake.

I have successfully installed the the 2009 Cockpits, and most of the cars (can't run them all until I build my new pc) and I don't think this will affect anything. (except maybe the prost team halting traffic in pit lane an not making it past turn 1 due to the failure rate in the performance file )

Also I downloaded the new version 1.1 and the torque files and can't wait to try them. I noticed that the .ini will not load so I exported the original and found that the line Scale=0,002 needs to be Scale=0.002 to load properly. I will try the new files out and let you know.

Thank you for these files, without them I would be stuck in the gravel trap for life

When I was developing the 2009 physics it took me weeks of testing to get used and exploit to the maximum, the increased tyre grip of the slicks. And then it also took me a long time to find good setups for my car, to find how to trim oversteering,get it balanced and make it competitive.

The AI cars usually break perfectly. We have to brake a very very little bit earlier, starting (like in real F1) with full braking and as we get to the end of braking we progressively lift foot from pedal to avoid wheel blocking.

I use 60 to 62 at the front depending on the track. AI cars are not exempt from physics rules. It happens at my PC to hit each other or miss braking and go off-track.

Make sure you implement correctly the performance files. Do you use a CSM or a non-CSM mod?
The gear ratios are defined in each track's magic datas.
In non-CSM mod magic datas have to be included in the track's *.dat file.

Seems like a calibration problem to me. Try to recalibrate your driving wheel.

Good luck on your troubleshooting.

Thank you for your reply,

I don't mind getting hit and going off because thatch realistic and that happens, but I seem to be lapped 4 times within 12 laps and eventually get rammed from behind or a car slips into my inside while I'm taking a hairpin. the AI should have said "Hmm, not enough room that would be an illegal pass" and back off, but no AI is ever perfect and again its not your physics doing this, Ill just have to deal with it.


Its More of the AI ignoring me, one example as when a force India car pulled into its pit area waiting to be pushed in and I had to wait for it to get clear before I pulled in. I waited for about 3 seconds until a Ferrari rammed into me and I lost my rear wheels and then there was a 5 car pileup in font of the Brawn garage. But this is not related to your physics.

I finally noticed other cars using 7th gear but not in the correct way I see the Real drivers on tv using it. They enter 7th just as they are braking on sepang while I am set up to enter 7th half way through the last straight and maintain 304kph similar to the real guys. Is there a way to edit the AI profiles as well?

With your Physics I have set up the Differential as you requested in the read me and am keeping the rear wing 2 degrees behind my front wing at all times and a lot has improved. On the Italy track, I use 16 front and 18 rear too aid in grip on the tight Corners. The front over steers just right and the rear stays on the ground. Do you have any general tips on car setup other than what the in game Gpedia has? I have raced over 300 laps on Sepang practicing but I have no clue what the setup should be for Monte Carlo for example. Sp far I have learned a lot and i'm eager to figure this out.

I am using a non-csm setup, I have just replaced a few teams and cockpits until I get my new pc and then I will use CSM with TSM. Right now I can't run more than a few new cars and new tracks are impossible.

Thanks,

Aiden

What happens is normal.
If you are lapped by the AI cars, you have to drive aside and let them drive through. It's you should do and what they expect you do.
If you lap an AI car, you will see it as you approach it from behind, to drive aside and let you overlap it.
It's the FAMOUS GP4 AI.

As I said in a previous post:

So, edit the magic data file and then insert it in the track's dat file.
you edit 6 gears but performance file make the Ai use 7.
Set the 1st gear to the desired value and then set gear no. 6 to the value that you use for your 7th gear.
Finally adjust the remaining gears (2nd, 3rd, 4th and 5th) to appropriate values.
Edit also the front and rear wings of the AI cars.

I don't know any more tips.
It's more a matter of experience that comes with practicing in many tracks.
Search around and you 'll find some tutorials on editing setups in GP4.

A very good guide that helps undrestanding even more the parameters of setting up a F1 car is this one:
[iroland.uw.hu]

In the next days I will post a link to my GP4 setup for Melbourne 2009.
I use it with ver.1.1 of my physics and with this performane file:
by kimifanaat - 2009 Melbourne Per[www.mediafire.com]
(link at pg.1 of "The guide to updating Grand Prix 4 to the 2009 Season"
In the perf file I set all cars to 785bhp power and left unghanged the drivers performances.
The result is that all qualifying lap times vary within two (2) secs - like in real F1 and when I drive for Button - Brawn I get the pole 1.
So, stay tuned for the setup link. It's generally a good base for editing more F1 car setups that work well with my physics.
