He has a brand new PC with pretty good specs, although the CPU is a bit on the budget. He can run all sorts of shaders, thanks to the good GPU, however the issue is on the CPU side. The game runs on 1 core only, so you'd actually need a high end Intel CPU to run 60 FPS and above in crowded areas. I face the same issues on a fairly good AMD processor as well.All in all, the most obvious fix would be buying a new CPU, although since it's a new one I doubt that.
So this thing is normal to occure as I understand ? no problems ? althrought I didn't install GPU driver only installed Geforce experiance, thought it would be worthy, should I install driver too ?,
yes you DEFINITELY should download your graphics card driver, or atleast update it
did that , still the same. althrought even descent PCs get FPS drops like I get in crowded places and so on ? like populated places ?
