• I'm not a fan of just taking everything to ultra, even if it's still smooth.
  The ART of optimization is to find the best visual and playable setting in all "dimensions".
  I find that this Setup is nicer and more playable!
  I've tested all of the setup options from ultra to low. If I couldn't find a difference, I'll take the smaller value!
  On the one hand, some settings disturb and hinder the gameplay, and on the other you also have reserves when there are larger, more complex game scenes.
  
  
• I only get it smooth with playing from my fast SSD!!
  
  
• I use a 50" Plasma TV with Full HD (= 1920x1080 60Hz). With a 2560x1440 DSR, a classic Downsample for better AA from Nvidia, the menu becomes very small, so I prefer the normal Full HD Resolution.
  If you have a true 4K Monitor, then you will use 120-144 Hz, which means you need 120 to 144 +FPS and that is not tested, but may work either!
  
  
• If it is not smooth, You may test smaller Resolution (3840-2560-1920) with 120 Hz.
  
  
• You have to set the Frame Limit to 125 FPS in the Nvidia Setup!
  
  
• I am not sure, whether the server clock rate can do 120 Hz, usually the tick rate is often 60 Hz !?
  If you will get network problems, you may play on 60FPS = 60 Hz, for testing!
  
  
• The grass option is ambivalent, it looks much more realistic and visually more beautiful with grass. But it is quite annoying, when you play from first person, while the AI "ignores / can not see" the grass and you can see nothing else - Lol!
