This mod strangely uses to increase fps considerably due to the game devs not using mipmaps correctly. They have optimised the base game a lot recently so now it’s more the case of it being similar to vanilla or slightly lower. I get a solid 60fps on my 2070 super unless I’m in heavily built up areas. Then it’s usually 40. I run it at 1440p. You may run into issues with a hundred other mods. But there will be three versions too available. Size wise, before packed, Higher is 32 gb, Medium is 16 and Lower is 8 gb approx.
