Forza Motorsport 7 capped at 17.9FPS... Any Help?

HI all,

I am in dire need of help. Everytime I run Forza 7 (PC) my gameplay is capped at 17.9FPS. This has only just happened after doing a windows update but since I have formatted my entire system and I am still left with the same result.

I run the game at 4K max settings and previously I was getting 80-90FPS BUTT even when lowering the setting to 720p and everything on low I get 17.9FPS again… I managed to change a registery setting that fixed it for one session and then the game closed and went back to the 17.9! Even on the bench mark I get smooth FPS on that but then it finishes and nothing changes.

My system is as follows:

i7 6700k
16GB DDR4 RAM
EVGA FTW GTX1080
Asus Hero VIII Mobo
2TB Seagate HDD (game installed on)
500GB SSD (Boot)

I am running all the latest updates from windows/game and all the latest drivers but still suffering this problem. Has anyone got any help or is suffering the same problem?

How can we report “A drop in frame rates” so that devs can look into it?
