Realized there was a gorgeous dirt and rubber buildup on the racingline that I never saw before. I raised the seat to see over the windscreen and realized it was there, but disappear behind the glass.
The window shader does have an effect on how the environment output. Is the racegroove completely missing, or is there a subtle hint of its presence?
I will have to check. I do know that I didn't realize there even were a graphical 'groove' until I raised my seat. I will do some screenshots when I get home from work.
The groove is there, just washed out. It got alot better when I switched to HDR, as the glare is much less when looking forward.
