Got my answer, doesnt really sound promising but figured it was something along these lines:
"Yep is a know issue :p
HDR was broken some years ago, but no one realized until was a bit too late.
Fix it will make all the content look different and is something i want to avoid as artists invest a lot of time trying to get the most from the engine
Is in my ToDo to check what are our alternatives in the next months, but i cant promise anything."
Kinda sad to hear. Looks are (in my opinion) a huge part of modern car sims/games so not being able to have that without external PostFx solutions kinda sucks. Can understand them though. Dont see why they cant 'fix' it and bring back the HDR On/Off option for those who think it looks bad. If its not really bad and effects more things than pure resources such as textures, then i can see why ofcourse. Weird thin g though that the gfx in the tech demo are alittle more on point with example speculars even with PostFx off.
Anyways, I reinstalled Reshade after this, in order to get alittle more updated gfx.
