It contains an update for a tyre physics issue, where the temperatures behaved differently depending on frame rate.
The fix will bring temperature behaviour in line across all three platforms, PC, PS4 and Xbox One, and regardless of frame rate. As we’ve previously commented, we log and assess all user feedback which we receive via any of our social channels. In some situations we’re able to act upon issues more readily than others, depending on the complexity and development requirements. In this instance we felt we could quickly and safely apply an important fix which will impact upon the validity of players performance in game.
