The reason this and RDR aren't on the PC is because the PC cannot handle this game, literally.
Thats probably the stupidest thing I ever heard...
PC will always have better graphics and quality over consoles, no matter what.
1. it cannot lower the quality
2. refer to 1
3. if your computer is that good, try an emulator
Incase you didn't know, consoles actually have to LOWER the detail to be able to handle it, not only lower the detail but also implement a frame cap to it.
Idk where you guys live, but im sure ANY modern PC you can buy now has more RAM then the PS3,360, and Wii combined (>1.5Gb)
