The more we hear about Monster Hunter World, the more we understand that it’s going to be no slouch in terms of pushing our PCs to their limits. Last time out we heard that even a GeForce GTX 1080 could struggle to max out MonHun World at 1440p screen resolution, and now Capcom is attempting to explain just why Monster Hunter World is also so CPU-dependent.

First things first, Monster Hunter World is powered by the same MT Framework Engine which powered most of Capcom’s previous-gen titles, including Dragon’s Dogma: Dark Arisen. Meanwhile, the absolute minimum processors are the Intel Core i5-4460 or the AMD FX-6300. Both fairly old CPUs now, although certainly still very capable for gaming purposes.

“While the MT Framework engine has been around for ages, it does a good job in distributing CPU cycles and load-balancing tasks across all available cores and threads” said a Capcom representative going by the handle WBacon. “The engine itself is optimized for x86 CPU instruction set, is highly scalable, and loosely speaking, is platform agnostic regardless of PC or console platform so as long as it conforms to the x86 instruction set.”

So that explains why Capcom is pleased with the MT Framework engine on a technical level, but why is going to be so demanding on our CPUs Well, that’s because it’s going to be loading entire levels into memory all in one go, and the CPU will need to keep track of monster locations, monster interactions, health status, item pick-ups, environmental damage, and heaps more.

“To eliminate interstitial loading during active gameplay, MHW loads the entire level into memory,” continued WBacon. “In addition to managing assets loaded into memory, it keeps track of monster interactions, health status, environment/object changes, manages LOD & object culling, calculates collision detection and physics simulation, and tons of other background telemetry stuff that you don’t see yet requires CPU cycle. This is in addition to supporting any GPU rendering tasks.”

It’s going to be interesting to see just how Monster Hunter World is going to perform on weaker CPUs then. From the sounds of things you’re going to need a solid quad-core as an absolute minimum, while performance should scale well for those with additional CPU cores and threads.

Monster Hunter World is out on August 9th for PC.
