This generation is 60fps, 360 and PS3 are 30fps
Metal Gear Solid V: Ground Zeroes is arriving on a number of different platforms, and differences are bound to happen. Because of that fact, Konami has provided a series of screenshots and information to "help you find the right version."
Here's the biggest bit of info -- the PS4 version will sport 1080p resolution with 60fps, and the Xbox One will run at 720p also at 60fps. On the 360 and PS3, they'll both run at 720p and 30fps. You can also head over to the website itself and look at some direct comparison shots.
So yeah, there you have it. Thankfully, Konami is being pretty upfront with the differences, however they came about.
