60 fps support is great, but unlocked framerates that can take advantage of high refresh displays are even better. When we first got a look at the PC version of Monster Hunter World, there was a lot of talk about 4K, 60 fps performance, but we're happy to confirm that World offers an uncapped framerate option on PC. Specifically, there are three framerate options: a 30 fps cap, a 60 fps cap, and "no limit."

In testing today on a few systems, we confirmed the game can definitely run above 60 frames per second, but on most hardware you'll need to turn settings down significantly to see high framerates.
