Random hang-ups during track-pre race loading

Forza Motorsport Legacy Motorsport
1

My system:
Intel i7 3770K, 16GB Ram, GTX 980 Ti
Ofcourse the game runs silk-smooth (…that would be the last straw…) at ultra detail in 3K, but i have random hangs-up during pre-race loading. No matter the track, no matter the event.
Pure random.

Any advice? Thanks.
