Did you set the res to 1920 x 1080 32bit in the config tool? Look in your main rFactor folder, it's a .exe close to where the rF .exe and the dedi .exe sit. I would leave it on DX9 or Auto, and I personally have AA set to "None" in the config. I set then set it to 8xs in Nvidea Profiler. I'm not in front of the game right now, but if you need clarification, let me know.
