Over on the official Titanfall 2 blog, they reveal that they actually want people to play, enjoy and experience the art of the game at reasonable settings. This means that the minimum specs are tuned to 1600 x 900 (progressive scanning without interlacing) and up to 60 frames per second.
They reveal on the blog exactly what their aim was for the minimum specifications, stating...
Usually minimum specifications are designed around what's the absolute bare minimum to boot the game up and play it at around 30fps (with possible dips). I mean, that's the whole point of the "minimum" side of things. Historically, "minimum specs" represented the absolute base specifications for getting the game to run... not to run it well, but to get the game to run at all.
Recommended specs were also designated for the top-end side of performance, a PC that could run a game like Titanfall 2 on the highest settings.
Minimum and recommended labels usually gave gamers an idea of what to expect from the performance of a game, especially if they were just above the minimum specs but just below the recommended specs.
In this case, Titanfall 2's minimum specs are actually quite steep. 1600 x 900 is putting it par the course with the resolution of a lot of Xbox One games. However, on the upside, you will only need an i3 CPU to hit that resolution. On the downside, you'll need at least a GTX 660 or a Radeon HD 7850 to run the game, which is kind of odd considering that the GPU requirements are higher than the AMD GPU inside of the PS4 and Xbox One. It definitely makes you question.
The minimum specs also have various graphics settings turned up in Titanfall 2. For instance, they have a list of the graphics options turned on for the minimum, recommended and ultra settings for the game. Weirdly they expect people with minimum specs to have AA turned on, a 16:9 aspect ratio at 900p, dynamic shadows enabled, ragdolls high, texture quality medium, and the other shadow options on medium. If there are options to turn those down to their lowest settings it's possible you could get away with a GTX 5xx series card.
If you have a big rig and you're already setup for 4K gaming, they have options available for those setups as well. Titanfall 2 benchmarks at an average of 76fps on the ultra specifications, which features an i7 CPU, 16GB of RAM and a GTX 1060 or a Radeon RX 480. Technically, 76fps on those cards at 4K is quite impressive.
The full system specs and benchmarks can be viewed over on the Titanfall 2 blog. The game itself is due for release on October 28th for the Xbox One, PS4 and PC.
