Headlights with realistic cutoffs

It would be so nice to have realistic headlight cutoffs

Found out this mod, and hoping it would be implemented in the vanilla beamng:

my guess as to why the devs haven't already done so

 

They could've make it as an additional setting to toggle in the graphics tab?

 

It's not even a little bit of lag, with one car on a map I usually get 70-90 FPS it drops to below 60, can't even imagine with more than 1 car

 

no idea why they don’t do this crap

 

The lag is mainly due to the shadows, with shadows set to partial, it doesn't have that bad of an effect.
