Disabling megane's windscreen reflection

Hi,
Is there a way to disable the Menage's windscreen reflection effects?
They take too much of my frames in Portugal and makes it difficult to race online, above all at the start of the race.
When racing, if I look back I see a get a lot of FPS but when returning to normal cockpit view I get quite a big drop in FPS.

 

Well, just uncheck the "Environement Reflection" in the Settings :

 

I'd swear I already have it disabled, but I'll check it when I get home.

 

There might be other things at work , I think by default when looking back the game is rendering less objects and its also not having to render any of the player car ( dpends how ISI have set it up)

I don't think the windscreen reflection should really be that demanding over other things (again depends on ISI's implementation).

Be interesting to know for sure
