Major performance issues after Update 5 (PC)

After Update 5 I’m experiencing major performance issues on my PC. For first 30 seconds of every race I have huge stutters and drops to 30-40 fps. During consecutive races it’s even worse, because I have 30-40 frames all the time. I need to restart the game. What’s more, when racing at night I’m experiencing some lightning glitches inside the car. This update is a huge mess and I hope you’ll fix it soon. Right now game is unplayable for me.

Thank you all for your input. We have been working diligently to improve the performance of the game with each Update. To make sure we have the most up-to-date information on performance and crash issues you all are experiencing, we will be closing out this old thread and encourage you to open new ones so we can better triage and monitor. Thank you.
