rFactor 2’s July 2021 Update and New Monza Layouts Released

Studio 397 has updated rFactor 2 and brought numerous changes to the sim including linked sessions to complement the Competition System.

The public branch of rFactor 2 has received a significant update this week. The racing sim’s July 2021 build brings a wide array of changes and updates, which you can find listed below.

Among the featured changes is the implementation of linked sessions in multiplayer. These linked sessions “allow the player to remain within the same server and engage in multiple sessions without having to leave and re-enter / re-register".

The effects of these linked sessions are significant to users. Reverse and custom grids are now possible thanks to this change. And perhaps the biggest news regarding the linked sessions is that road and time progression is now possible within one multiplayer session. So weather, time, and road surface progression carry on throughout the event.

The update comes one day after rFactor 2’s Monza circuit received a significant update of its own, with Studio 397 giving owners of the Monza DLC two additional layouts.

The Junior circuit is a shorter variant of the track and eschews much of the reason Monza earns its “Temple of Speed” nickname and cuts the standard 5.8-kilometer length down to just 2.4 kilometers. The shorter layout plays nicely with lower-horsepower cars and affords them lots of overtaking possibilities.

The second added layout is the Grande variant. Unlike the Junior layout that caters to handling rather than top speed, Grande is best suited to cars with higher top speeds. The famous (or infamous in sim racing circles) turn 1 and 2 Rettifilo chicane is gone, allowing you to potentially be flat out from Parabolica to Variante della Roggia. Slipstreams will be a major factor for racing here.

The core game update for July 2021 is live now for all, along with new layouts of Monza for owners of the DLC.

Do we need to opt in "release-candidate" in Steam to get this update or is that not necessary?
Can anyone tell me if they fixed the absolutely horrid shadow effects from fences, especially on the oval tracks?
They are currently working on shadows, posted in a roadmap a month or so back, but I don't know of a timetable for that.
When I first saw the 'Metallic Noise.' change, I thought we were going to get a sound FX for the bottom scraping the pavement. just a graphic change however.....
Anyone know what this means?
· Added UI setting for toggling FFB strength direction between negative and positive

Does that mean we have in-game ffb strength adjustments now?
