Thanks for further clarifying...

I think the problem you're probably seeing here is the difference between 60fps (on the PS3) and 30fps (on the Vita) - I say "probably" because there's lots and lots more considerations, (physics update frequency, collision mesh differences, etc etc)

The PS4 is super powerful, so we've always opted for the "most expensive" option in every area of the game. I'm sure you'll have no need to worry
