GPL Slipstream Patch - New version WIP

#1

Post by PTRACER »

After many, many months of work and testing I am pleased and proud to announce the release of GPL Slipstream Patch Version 2.

The included features are listed below and I suggest reading the Readme very carefully from start to finish so you know how the patches should be installed and understand any caveats to running this patch.

Code: Select all

========================
======= Features =======
========================

1. Updated version of GPL's slipstream model, which now behaves mathematically like the 1967 Lotus 49 portrayed in Assetto Corsa.
   - It is now mathematically 1/11th the size of that portrayed in the officially released mods.
   - The calculation itself has been modified so it is no longer linear with distance, but falls off more gradually to begin with before
     dropping off sharply, thus representing a more 'realistic' shape of wake turbulence
   - Slipstream calculations have been equalised across all mods (some mods use multipliers which are not present in others)
     
2. Restoration of a piece of code that was broken in the 1967v2 Historical mod that prevents engines from blowing when overrevving 

3. Server checking code that ensures any players who use this patch will be unable to join unpatched servers and vice versa

4. Comes in both 36fps and 60fps flavours

5. Includes a standalone LR (or "Low Revs") version, which prevents AI in certain mods from exceeding their maximum revs while warming up on the grid

6. Includes code which prevents Best Lap data from being written to the player.ini files, thereby negating any impact on GPLRank.
Since I am going on holiday for the next few days, I have decided to release these at The Fastlane only for now. Next week I will upload to the GPL Addons site and promote it more widely once I have confirmation from those here that there are no bugs that need fixing.

Enjoy!

Congrats on the release! Thank you again for all the big amounts of work you put into the game.

Might give it a whirl if I finally get going with my 100% RD series again. 😅

I am sincerely sorry to the guys of the Mybroga league. The gpl.exe I supplied in the ZIP was junk. This came from Olaf's dirtgearpatch ZIP and purported to be the latest gpl 1.2.0.2 UK exe. Actually it's not working.

I have uploaded a copy of my own GPL EXE to the ZIP and updated the version to v2.01.

No problem, Paul! Thanks a lot for your help with the patch.

We'll race this season with the previous 60fps patch, but will test the yours to hopefully using it the next one. I think the main problem we had was that some guy(s) had both patches ticked in gem.

Cheers! Marcos

Paul,
The in-game car options don't work on 67-EXTRA (1 to 7) with 99a Slipstream v2 36fps Main.xml, same for the 60fps version
The 99a Slipstream v2 69XGT.xml works fine with 69-EXTRA, in both versions 36fps and 60fps.
I didn't check the LR yet

Hi Remy,

Thanks for your feedback. I just tested and managed to replicate the problem. I'll start looking into fixing it as soon as I can, though I'll be on a 2 week trip to the UK from next week so might not be able to do anything until May.

@Remy Roesz I believe I have fixed the problem. Patch updated to v2.1b. Please test and share your feedback.

@mcmirande - It seems Remy experienced the same bug as you regarding car graphics selection. Please try the new version shared in the first post and share your results.

Works fine here now, thanks Paul.

Now I'd love to have a version without the code which prevents Best Lap data from being written to the player.ini. I'm not a ranker :mrgreen:

At least for the 67Hx which is not "ranked" nor used for online races
