You have just completely contradicted yourself o0... your saying it does happen to our eyes but only when looking through the windscreen... then it doesn`t happen to our eyes and only happens when we`re looking through glass... The human eye does not create lens flare at all, all we get when looking towards the sun is extreme brightness that makes us want to cover our eyes to protect them (sunglasses) or look away altogether... looking through a windscreen does not produce lens flare either. It`s called lens flare because it`s produced by a lens, a man made lens not the ones we have in eye`s... I`ve been driving for 20 odd years and never have I seen lens flare coming through or being emitted by the windscreen... there may be a small amount of light distortion but not lens flare. For the sake of realism (IMO) rf2 does not need lens flare when we are in the car, not the type of lens flare everybody thinks of anyway. To have it in trackside cams etc would at least be realistic and whether or not we get that in game is up to ISI but as I say, at least that would realistic.
It would not be amazing imo it would crap... In reality when the windscreen is dirty and the sun is shining on it the first thing we do as drivers is put the windscreen washers/wipers on to clean it. As Tim has already said, remember all the complaints about the windscreen already being hard to see through... not needed IMO.
Shaders... look at picture below, the car has proper shaders to manage the ray lights, the rest of track has not... the 3d builds don't reflect the light as they should even being exported as "facet" smooth. It's rF1 by the way, but this lack of light power persists in rF2. HDR is just a subterfuge that doesn't correct this. Some 3d buildings faces should be much more brighter. They even looks like a billboard, but they're fully 3d modeled.
