Studio 397 yesterday evening released a new BOP update and physics tweak to the 13 GT3 cars available within the simulation.
  • BOP performance updates applied.
  • Tweaks to sliding behaviour.
  • Updates to aero draft issues
Studio 397 last night released a new updated for the full GT3 collection of cars within rFactor 2, adding a number of physics tweaks and balance of performance modifications to the category in a bid to further close up the performance differences between the cars, and address some balance issues that have been reported within the category in recent weeks.

As well as the usual BOP updates, the new builds also contain changes developed in order to resolve an issue where cars would lose excessive grip when following closely within the slipstream of another driver, and also changes have been made to reduce the ability for a driver to excessively slide the car in order to gain additional laptime advantage.

Could do with some vintage tracks for those lovely vintage Brabhams and Mclarens. Spa 66 Comes to mind immediately!

Historic tracks

Belgium '66
Isle of Man
Italy '66
Bridgehampton
Crystal palace
Cadwell Park
Castle Combe
Djursland
East London
Eifel Betonschleife
Eifel Südstrecke
Gnoo Blas
Hockenheim '66
Jarama
Le Grand Circuit 1967
Longford
Mexico '66
MonteCarlo '66
Riverside
Sandevoerde '65 and '67 ( Zandvoort)
Silkeborg
Targa_Florio
Rouen-Les-Essarts
 
Tracks needed from the mid to late '60's:
Vintage Road America(same layout but trees much closer, no guardrails)
Edmonton(not the champcar circuit)
Vintage Watkins Glen(late 60's)
Vintage Road Atlanta
Vintage Laguna Seca(the '60's version had no infield, just a squiggly roval)
Vintage Mosport
Stardust(Las Vegas)
Kent Washington
Ontario (Indy Clone) Roval
Vintage Sebring
Vintage Rolex (daytona) roval
Donnybrooke

Also there is a version of St. Jovite called Trembling Mtn. that has a 60's layout included. Mid Ohio was in use in the late 60's, I'm sure the environs have changed, but the track is most likely the same today as it was back then.

This kind of licenses don't have a time limit. When ISI acquired the Chevrolette license for the cars in their game, that license covers the use of that specific content in RF2 forever. And the game is still RF2, is not a remaster, not a sequel. The developer changed, but the licenses stay. Of course when S397 makes a dlc with new content in they have to acquire the licenses for that. Same thing if they decide to make a most recent version of that Camaro. But in order to update that same specific car (the model and liveries available now in game) they don't need a new license.

If the license for the Camaro would be expired, the car would have to be removed from the game. But it's not.
It's just a matter of what S397 wants. They want to push the dlc content and the content that works well online. The other stuff come after. As I've said, eventually they will update everything, but they are not in a hurry.

Both Codemasters and Simbin have removed content related to older/previous license.
So the above statement may not always hold true. We do not know what kind of license agreement was signed.

Don't know about Codemasters but Simbin removed cars when the product went to Steam. In that case their contract considered Steam as a new "platform" reason why some had to be removed. License is for title + platform. I.e afaik if you want to release a racing game on consoles + PC you pay 3 licenses
 
RF2 went to Steam under ISI and all the cars and tracks were present, so this is not the case. S397 own the licenses for every piece of content in game, otherwise they would have removed the unlicensed content. If they don't update some old content to the new standards it's just because they have other priorities or they aren't planning to do that at all. But, considering that they started to update old content already, there is still the possibility that they will update most of it in the end. A different thing is fantasy content, like Monza Historic, because if they are planning to acquire the license of the track in the future, there are chances that they delay that for when the modern layout is secured, laser scanning the full track surface.
Yes, that's what I mean. They can update if they want to.
I hope they don't touch the Camaro physics tho
