I'm not sure if there is much you can do beyond changing the HDR setting - either using a different profile, or turning it off altogether. Is this an issue that occurs all of the time, or only at certain times of the day on track? What I mean is, does the position of the Sun affect the amount of windscreen glare? I had this problem a while back - during a 12 hour endurance event no less - and made the drastic decision to change the camera that I use for driving - there were also other advantages of this, though I appreciate that this may be something that you don't want to do. This does make driving incredibly difficult - the windscreen seems to become translucent, and almost close to opaque; can't for the life of you see where you're supposed to be going. Not only annoying, but also rather dangerous during a race. Another quick question, does this problem seem to affect some cars more than others? I found that this was the case when testing to replicate the issue.
