Performance Issue + No FFB

Hi All,

I'm really struggling with RaceRoom.

I have a pretty decent computer (i7-8700K @ 3.70 Ghz / RTX2080Ti / 32 GB / 1 Tb SSD) with a triple screen setup.
I run my games at max specs with a resolution of 7680 x 1440, and usually I get a solid fps. For unknow reasons, I can't get even 30 fps constant with the graphic settings at the lowest.

Also, I have no FFB with my Fanatec CS Wheel Base 2.5 while the wheel and the base are recognised and functional.

Any idea?

Thanks
Damien
