F1 2020 - Tire performances for 25% race length and others mods 2.3

Hello all,

Introduction

This is my first mod (and sorry for my English). At the beginning I wasn't satisfied with the management of the tyres proposed by the game if the race length is set at 25%. There is always only the same strategy proposed (1 stop), and the IA stayed on the same strategy everytime.

Moreover, i was very happy to discovered some excellent mods like F1 2020 TyreTempMod from andyandy989898 . His mod inspired me and i tried to update it for my own game experience. Thanks andyandy989898 !

So I made my own mod for the tire performance for a 25% run, with some other changes for the Wet and Dry tires to be more realistic but not too harsh, especially with the realistic rain mod!

I also use a lot of other mods. Some of them concerned game mechanics and graphical improvements, like reworked sparks, real tire damage….

I decided to build a package to merge some of them and my own mod so that I could reinstall everything quickly.

Content of this mod

This mod contents the core part of the package that i use before adding others skins. So, my personal tire compounds and vehicle settings, combined with some other mods.

Tire Compounds part

Tire compounds adapted for a 25% length races and multi stop strategies, to keep a consistent AI behavior, and with a properly updated strategy panel. I updated too the Wet and Intermediate tyres to have more specific (and limited) use. For grip a standard curve is use to keep performances with an acceleration of wear with several phases.

The grip curves (depending of wear) :



As a result, if you (or IA) try to hold your tyres on for too long, the grip will drop quickly and you or them will waste a lot of time. You can easily feel the grip start to disappear at 20% -30% depending on the tyre. So take care of your tyres. The strategy tables are ok*.
(* some mods only change the "tire wear rate" on tyrecompounds.erp for a 25% race lenght but without any impact on the pit stop tragety, so the AI behavior become inconsistent)

The wear (wetness) globaly :



The result
Different strategies are proposed and used by the bots which are globally effective, also depending on your position (being in the first 10 on the grid or not), and so depending on the condition of the soft tyres you used during qualifying, and for each configuration (C1 C2 C3 tracks, C2 C3 C4 ...) :








1, 2, or 3 stops on some races are offered and may be relevant, for first 10 or not drivers.

Others mods and changed included

• Sparks reworked. Thanks to Ls_Tech
• Realistic Rain. All credits of the mod goes to vlasovas and guina60.
• Real tire damage for Slicks, Inter and Wets Version 1.3 from micmiller
• Performance mod 1.9 from EnriqueBanderas which included others mods like improved dirty air mod and damage mod from StrongestFish

Special thanks to them their mods are just awesome and I couldn't play without them now !

Some other changes:

• Puncture wear is set to 95%. Why? because IA doesn't have puncture. I have updated the tire mixes to have a strong degradation of tire grip, so you will have to make the right decision whether or not to keep your tires after 65-75%….
• Wear are modify through :
  • teams vehicle files : <UpgradeWearFactor value="2.0" /> , for IA, FOM & My Team vehicles.
  • tyrecompounds.erp file (around 25%, depending of kind of tyre) to adjust the wear in the race with the strategy estimates.
• Aero slipstream effect is slightly increased to help for overtake. Lift effect stay globally raisonnable, so keep control of your car when you will try to overtake a slower car which did 1 pit stop only with hard compounds !

It is these two developments in the wear data (along with the new tire grip curves) that give me a good balance for a race length of 25%, with good tire wear during the race compared to the predictions made by strategic panels.. Obviously the prediction is not 100% correct, depending on your skills and your driving behavior, the settings of the car, the weather, the development of the team too…
The original grip of each tire is also updated, as the grip curve to achieve a good balance between each strategy, the selection of tire compounds and the tracks.

Some tips

• There are now several strategies. Sometimes more than 2… and obviously depending on your position on the grid. Sometimes the 1 or 2 stops could be the best… or not, it will also depend on the traffic and the behavior of the hard compound on the right track. Try playing with the strategic panels to check out other options. Temperatures could be a real issue on some tracks for hard tyres ...
• Because of the damage mods, and because the AI will take so many different options, you'll get a lot of traffic… and sometimes crashes. You need to take care of your pit stops to find the optimal settings and maybe avoid traffic. Starting by soften tyres is not always the best idea, for example.

Examples here with 4 different options with less than 5s between for a 25% race lenght

• Use your soft tires wisely during the qualifying phases ... ... this will have a more or less strong impact on your options after, at the start or during the race. You will no longer be able to do half of the race with soft tires.
• Wet and dry tyres have a very small box of optimum performance. You could be severely penalized with wear or grip if you don't react quickly.
• Focusing on a strategy with only 1 pit stop mainly ... is no longer the only one and best solution in every race. Hard compounds are clearly more difficult to use. It's always possible to come back from the bottom of the grid with this strategy but it will take a lot of effort and defensive skills .

Concerning F2 races (2019 & 2020) :
Work in progress but too many issues with IA and tyres/pit stop strategies for 25% race length, with a main race and a sprint.

Installation

It's a copy & paste installation:
Just copy and paste the directory /2020_asset_groups in the directory of the game. That’s all.

XML file of all cars is included. This can be useful if you want to add (for example) a skin mod for My Team. It's for who wants to work on it with EGO ERP Archiver.

This mod is made for a 25% race time ... so at 50% or 100% I think it could be a nightmare with too many pit stops ...

Recommendation (s)

• I recommend using this mod with a small qualifying phase (18 min). (to keep coherence with the soft mixes wear updated).
• Desactivate the Safety Car. It dont make sense for a 25% race lenght, especially with Damage Mod.

AN : It is difficult to find a good balance for each track without penalizing the top 10 drivers on the grid and keeping a good fight between each strategy on a 25% race lenght. The main problems relate to tracks like Singapore and C3/C4/C5 compounds. But I preferred to keep a little potential on the soft tires to avoid pushing the drivers to pit stop after only 1 lap ...

To uninstall

- Steam have special option for it :

Click on game by right mouse button in Steam library

Choose Properties - Local files - Verify integrity of local files. After this Steam will start checking game files and will restore modded files to originals.

- You made a copy or your original 2020_asset_groups directory. Nice ! You are careful.

This Mod not works in multiplayer (online).

There might still be some weird behavior, I tested it for several weeks (and many My Team seasons) but difficult to check everything.

I made this mod for myself at the start. But if it can help other players, so much the better ...
