Part of why Titanfall doesn’t look amazing is because the game was developed with Valve’s last-generation Source engine. While its resolutions and textures might look a little shinier on the PC and Xbox One, the tech powering Titanfall isn’t exactly modern. Most of Valve’s popular games, Portal 2, Team Fortress 2 and even the ancient Half-Life 2, were all built with Valve’s source engine. Of course various upgrades have been applied to the engine over the years, but it is still fundamentally the same.
