[Performance Issues] Extreme performance issues with new update

[Tartee]

Hello, ever since the Flying Finns update came out I have been unable to play Dirt Rally. With medium-low settings I was able to get 60+fps in most parts of the game and with the very low preset I was able to get around 120fps if I remember correctly. But ever since the update came out I've been getting sub-20fps in my usual settings and almost 30fps with the very low preset. One thing I have noticed is that whenever the car isn't on the ground the game will run smoothly but as soon as it lands it will bog down again and turn barely playable. 

My PC specs:

AMD Phenom II X6 1050T

MSI 785G-E53
4GB DDR3
AMD ATI Radeon HD5850

Is there any fix on this or anyone else suffering from this problem?

Thanks in advance,
Tarte
