F1 2015 Silly question

[animal690]

on graphics settings
I have skidmarks blending intel and advanced smoke shadows intel is set to off and cant turn them on.
Why is this

Maybe your not using Intel graphics, like the on-chip graphics I have on my i7-3770k. I use 2 screens as an extended desktop, and have the on-chip graphics running my 2nd screen (desktop only).

I can't use those game options either, probably because I am using a pair of AMD graphics cards to run my main No.1 screen

cause switch is automatic and intel card doesn't work
