Like the majority of AAA blockbusters arriving these days, Just Cause 3 has some fairly eye-popping system requirements. No doubt you’ve seen them by now, but if you haven’t then you can read all about them here on GD. They’re definitely near the upper end of the hardware scale, but we’re used to games demanding more on the back of the box than they do in practice.

With that in mind, we thought it best to come right in at the low end and see how the diminutive GeForce GTX 750 Ti performs, assisted by a doddery old AMD FX-4100 CPU, and just 4GB memory. In theory, if Avalanche has got its sums right, this rig shouldn’t be able to run Just Cause 3 at all.

By now, we’re so used to inflated system requirements that it comes as a bit of a shock when they’re bang on the money. As it turns out, Just Cause 3 is. When you go and take a look at the Just Cause 3 system requirements, I don’t really hesitate in telling you that’s pretty much what you’ll need. Don’t even think about playing this with less than 6GB RAM or an aging processor. Neither cut it.

There is a caveat to this though. I believe the GeForce GTX 750 Ti is almost definitely enough to play at Low / Medium settings, but it’s being really held back by the CPU and system memory on offer in this rig. Because of the poor performance it took an age to tab out and get the image below, so the CPU load has dropped, but it was sitting in the region of 90-100% at all times with the AMD FX-4100.

The real killer, however, was the RAM usage. Just Cause 3 eats it up. When Avalanche said you’ll need 6GB as a minimum, they really weren’t kidding. 4GB just does not cut it at all here, with memory load sitting at 100%, all the time. Because of this, memory usage spilled over to the far slower hard drive, which was also sitting at 100% use. This led to major frame rate hiccups which rendered Just Cause 3 unplayable, even with absolutely everything dialled down to the absolute minimum, at 1280 x 720 resolution.

Visually it looked extremely poor, and we know from prior experience that the GeForce GTX 750 Ti is capable of far more than this. It’s undoubtedly being bottlenecked by the other components, which renders Just Cause 3 totally unplayable on this system. We're going to be getting hold of some more memory for this system soon so we can provide some more accurate benchmarks of its performance. 

Next up we'll be slotting our GTX 950 into a system with plenty of RAM and a high-end i7 CPU, so we can eliminate the other bottlenecks and focus on GPU performance. As it stands we can't get a very good gauge on Nvidia's card, so don't lose hope of playing Just Cause 3 if you're sporting a low-mid range GPU.
