It would be nice to have a option to disable dynamic headlight shadows and leave just the light effect. Because the headlight shadows can be pretty hard to render on older GPU's like mine. It would probably result in a lot lower FPS loss when using headlights it takes off atleast 5-7 FPS.
Sure thing. For now this is possible only editing lights through editor. That would be nice to see option like "Enable/disable main lights shadows (headlights)" and same with additional lights (blinkers etc.).
Best solution here is to get a graphics card, even just a cheaper one (like $100). Intel graphics are not made for gaming.
To get a reasonable card price to performance wise, you need to spend about 150 USD. You'd want to get the R7 370.
