Yeah, yeah, the title was a bait. Also, yeah, PC still didn't get GTA 5. We know, thanks.
And, yeah, this is a modded version of GTA 4. But, damn, just LOOK at this! And yet you can get this too, completely for free.
From "about" below the video (not my PC):
My PC: i5 2500k, 4gb, GTX 660
Average framerate is usually 30-40
And yet those dumbarses from Ubisoft say how we'll get a complete "next-gen" experience with Watch Dogs. Just hilarious.
