rFactor 2 latest beta includes new particle engine sounds and effects

The latest rFactor 2 beta includes new engine sounds, revised AI, and more options

A new test has been released for future rFactor 2 updates, and along with the new sounds, it includes additional setup options, UI additions, and AI tweaks.

A new candidate version of the Working 2 PC based driving simulator has been released – and includes a host of gameplay add-ons.

For those out of the loop, the rFactor 2 release filter is an optional preview of upcoming features and feedback will help the development team ahead of the official launch in the future.

Chief ones revised engine sounds. This will be in effect both outside, for replays and esports, and inside vehicles. In the example shown at the end of a teaser video, the LMP2 machine appears to have more texture to its engine sound, with crisper pop and pulsations when overtaking, and more feedback from the transmission.

In the same view, you can see more sparks added – reminding us of The RaceRoom Racing Experience update from the middle of last year. The Particle Effect update also includes changes to puddle spots.

The Chevrolet Corvette Safety, or Speed, has also seen a new makeover, now with Physical Display (PBR) for more photo-realistic visuals. However, the C6 body style remains.

A major change in gameplay is the protection against underspeed. Smash the gear paddle down too quickly in the past and that could overclock the engine and result in retirement – which is exactly what happened to Daniel Juncadilla at the 24 Hours of Le Mans Virtual earlier this year.

rFactor 2 Corvette Safety, update April 2022

There are many changes to the user interface. Significantly revised in January, new features have been added to help prepare a wet track with greater accuracy, select vehicle options, and eliminate AI opponents. Speaking of which, they are said to be much smarter when it comes to tire strategy – we have to see how it actually works.

Below is the full changelog, also highlighting the variable lighting effects and driving line aids. Let us know in the comments below what you think of these upcoming changes.
