Automobilista 2

Reiza Studios deployed Update V1.5.5.2 for the Automobilista 2 racing simulator.

This latest update brings you another batch of physics and AI improvements along with further updates to both new and old content, including more tracks with support for the new flag LED panel feature.

A minor but notable adjustment to the tire modeling of both modern slicks and wet treads has been fast-tracked with this release, sharpening up the feel of the tires that received the adjustment – these are listed in the changelog below. The changes have no major repercussions on user setups or the overall performance of the cars.

On the AI front, adjustments to AI lateral movement rates, and distance passing routines are triggered to on, and enabling a function for AI in faster cars to “see” slower cars further up ahead has made line switches more flowing and also reduced hesitation both when passing for a position as well as dealing with lapped traffic. Further improvements in this area are already in the works. AI also improved for several tracks with a new batch of fast-line redos.

Multiplayer logs and reports welcome:

On the Multiplayer front, users that experience showstopping reliability issues are now welcome to post their session log files in the forum to provide us with valuable info towards debugging these remaining

Reiza Announcement:

The AMS2 + Season Pass 2020-2022 Bundle has now been deactivated from the Steam store page – it has been replaced by the AMS2 All-Inclusive Bundle, which packs AMS2 & all DLC items necessary to make it complete at a 15% discount.

As we progress with new DLC releases, the Bundle will be updated accordingly – this way, new users have a single-click option to acquire all existing AMS2 items at any point in time without duplicating DLC purchases, while existing users get the option to complement their install with only the DLCs they might be missing.
