Sony is "actively push[ing]" for PlayStation 4 developers to deliver games that render at 60FPS/1080p, according to a developer working on the console.

Discussing the differences between PS4 and Xbox One with Eurogamer, Stewart Gilray, who is working on a secret PS4 game at Just Add Water, said:

"We might see slightly smoother framerates on PS4. We're working with Sony right now, and they're trying to actively push 60 frames per second, 1080p.

"You might get situations where the graphics will be a little, but not much, lower quality on the Xbox One," he continued. "Or, you might get some fixed at 30 frames per second situations in 1080p. It depends on the scale of the game.

"If your game is going to push the heck out of the PS4, you might have to do some little tweaks [for the Xbox One version]. But if you design your game to work on Xbox One at 60, it's going to work on PS4 at 60."

The difference in performance will likely come down to the boost offered by PS4's 8GB GDDR5 RAM, which Gilray previously told had been kept secret from third-party developers prior to the console's reveal.

In comparison, Xbox One features 8GB of slower DDR3 memory, of which 3GB are reserved for system resources.

Both consoles are due to launch later this year.
