First, I am getting pulsating light when I turn HDR on. The whole screen literally pulses. Second, I was able to get huge frame rate increase using AMD 5900 series with everything maxed out by turning all catalyst features of other than texture (midimap and antioscopic filtering I think). Are there recommended settings for rfactor and config mod and catalyst? Or do I need to go to engineering school to figure out proper settings? For the record, I am not using any anti-aliasing and frankly am perplexed by all the redundant options in catalyst, rfactor "config mod" and in game settings. Any advice or referrals to good materials to understand this stuff would be much appreciated or even better if some with 5900 series has already cracked the code and is willing to share settings. Last thing is that I have a very robust PC.
