Having played MO2 at both 120+ FPS and at 60FPS. As long as I dont have any dips in frame rates it doesnt matter if I am at 120 or 60. I play at 60 because my GPU doesnt have to work to keep a stable 60fps. I dont experience single digit lows and I dont have sudden spikes of 200fps then drops to 10. That is when you will notice the difference. If it is stable 60fps the whole time I will perform just as well as someone who is getting 120fps and lows of 10 if not better.
I do notice a clear difference and I can tell that I perform far better at 120 then 60 FPS. IDK how anyone can say it doesnt matter. There is a reason most pros are doing what they can to get higher frames because it does matter. Its 2022 we the studies have been done over and over and people know there is a difference between 60 FPS and 120 FPS. To me Its like a slideshow moving really fast compared to something that looks more like reality.
Even then there are people who struggle to get a solid 60 frames in this game. People say as long as you have stable frames then its fine at 30 or 40 but I dont see any setting to lock the game at 30 or 40. Only 60, 120, 144, and 240.
Why does it matter to other players if some players can turn off shadows and grass? Doenst affect your expedience so why argue against it?
