The Order: 1886 runs at 30 frames per second, yet it feels definitely very fluid. Ready at Dawn CTO Andrea Pessino told DualShockers the reason why at an event in Milan.
Pessino’s mentioned that the game’s fluid performance is a combination of two elements.
Firstly, not only the 30 FPS framerate is fully stable, with no dips under that threshold, but the development team implemented post-processing filters aimed to make it feel even more fluid, like temporal anti-aliasing, which Pessino defines “extremely effective.”
Secondly, the game’s rendering frame rate and simulation frame rate (basically the frame rate at which all the inner workings of the gameplay are calculated) are the same, and there are zero frames of latency between the player’s input and the action on the screen.
Pessino mentioned that many games implement one, two, or even three frames of lag after the player inputs a command, and that makes the game feel more sluggish.
On the other hand, for The Order: 1886 Ready at Dawn decided not to resort to that development trick, so the player’s action is executed during the same frame as it is prompted (pretty much as it happens with the most responsive fighting games).
This, according to Pessino, requires a bit more complex engineering compared to systems that involve a slightly delayed response, but contributes to make the game feel much more fluid and responsive.
