I have left the settings as they are as seen in my intro comment. I have turned the FS graphics settings from med to high, buildings, trees, clouds, and increased the traffic to 70%. Have not noticed any reduced performance, but it looks much better visually. I am surprised at such smooth performance with my i7-6700K cpu (overclocked) , and only a GTX980Ti! Maybe the extra 16GB ram helps to 32GB. Obviously SSD drives, helps too, and I regularly optimize and clean the drives.
