During the latest monthly broadcast, Forza Motorsport Creative Director Chris Esaki detailed the updated AI that players will experience in the upcoming racing game.
Esaki explained that in a game like Forza Motorsport, the AI system has two sides: the AI controller, which is how the computer-controlled racers brake, throttle, and steer, and the driving line, which is the path they follow. track. According to Esaki, both of these systems have been completely redesigned and are in line with the main principle of the game – clean, competitive circuit racing.
To do this, Turn 10 essentially redesigned how Drivatar works. Previously, as you may remember, Drivatar tried to replicate the real behavior of real users on your friends list based on their previous Forza races. However, this meant that the behavior of “unsafe drivers” was also reproduced in your races, which could turn them into a kind of Destruction Derby.
User behavior will no longer be simulated in the new Forza Motorsport. Only skins and other customizations made to cars and driver outfits will carry over to Friends Races using Drivatar.
To create the fastest possible AI without any cheats, Turn 10 used machine learning to master all combinations of track, car (including upgrades) and weather conditions. If Forza Motorsport 7 had only three movement lines that were manually added to the game by developers, then in the new Forza Motorsport, nineteen movement lines are provided for each combination.
Compared to the previous game played at the Maple Valley circuit, the upgraded AI was 13 seconds faster. AI now uses all the features of the track, including pulling to the side of the road, and even looks more believable.
It also means that while there are no script errors, “honest mistakes” by the AI are still possible from time to time.
Esaki also revisited the subject of the collision model. He previously mentioned a 48x improvement in system accuracy in the new game, but this time he showed that the old physics were causing the suspension to jump and behave wildly. The new system should provide improved manageability.
Forza Motorsport is set to release on October 10 for PC and Xbox Series S|X.
