With on-screen action and physics that would make Michael Bay green with envy, Just Cause 3 was a notoriously CPU heavy game. According to Digital Foundry, Just Cause 4 pushes the envelope even farther, implementing weather-based physics and even more outrageous stunts for Rico to deploy. The devs have reportedly been hard at work optimizing this version of the game for multi-core CPUs, and DF seems to think that it runs surprisingly well, given the pre-release nature of the testing and the sheer amount of in-game action. Check out the analysis video here. I initially saw the game being played at maximum settings at 4K on a Core i9 9900K system paired with a GTX 1080 Ti. This is a comprehensive work-out for the GPU in particular, and frame-rates average out in the mid-40s - though bear in mind that both Nvidia and AMD are still working on their GPU driver updates for the game's launch, which were not available when we took a look at the game. Interestingly, Just Cause 4 is slated to include support for Nvidia's DLSS upscaling technology. Assuming that the quality level holds up and that the DLSS gains we've seen in demos so far translate across to actual gameplay, there's scope here for the RTX cards to hit a consistent 4K60 without the need to dial back quality presets.
