I think some of its problems has to do with how it uses the system ram as Vram on the consoles, some people said turning of your page file helps.
Very well could be, I haven't turned off page filing or modified the OS setup when I did the comparison. I kept everything pretty much stock cept turn off unnecessary programs and background applications.
Though to add, did the people who turned off page filing(virtual memory)do so on a traditional C: Hard drive, or did they have an SSD? If they had an SSD as their main drive I don't see the point at all.
