awaiting information [PC 1.12] FPS Stuttering since Patch 1.12

[Nipulv2 0]

1.       A detailed description of the issue. Please include any error codes here

Every since the patch 1.12 which occured a few weeks back I've had FPS stutters during every single "hard" turn and in straights. This leads to a very rigid driving and makes the game unplayable. Before that it was always fine. Happens in single player mode (my team) on every single circuit and on time trial. The game is smooth, then rigid again, then smooth again, then rigid again in the next turn. Steam-based FPS counter stays consistent. I didn't change or touch any ingame setting, it suddenly arrived after patch 1.12.
