Forza 7 Only uses 2 cores / 2 threads now

It has been a few months since I last played. But I noticed just today that the game is only using 2 cores / 2 threads on my I7 4770K and the game runs terrible now… Any ideas?

System specs

I7 4770K
970 GTX X2
16 gig DDR3
2TB - Evo 850 SSD

Software specs

Windows 10 Home version 1803 / OS Build 17134.167
Forza 7 version 1.133.8511.2
Nvidia Drivers 398.36

Disable HT and run the game. See if that fixes it. If not, try lowering CPU intensive graphic options.

My i5 runs on all 6 cores pretty steadily. I only see 100% on two cores when starting the game. During gameplay rarely does one or two get passed 40%. The rest are anywhere from 8% to 20%.

My old i5-3570K uses all 4 cores. I spike to 100% on all 4 cores during loading and maybe a full field rain race…but it runs smooth 99% of the time on my older system.
