Dying Light: Great Game; Demanding Graphics Engine
Dying Light looks great at all detail level settings, and to play it comfortably at 1080p with low or medium details enabled, a GeForce GTX 750 Ti is your best bet. Picking one up for as little as $150 is hard to argue against when it bests the more expensive Radeon R9 270X. This is my recommended minimum card for this game if you're not too picky about staying above 60 FPS at all times.
To play without stuttering or annoying frame rate drops, the GeForce GTX 980 is naturally your best bet at 1920x1080 and up if you want to maximize graphics quality. As usual, 4K absolutely wrecks performance, so I can't recommend any specific card for that resolution since everything we tested averaged within 6 FPS of each other. Only Nvidia's GeForce GTX 980 was able to maintain a minimum above 25 FPS. In general, AMD graphics cards don't perform as well as GeForce boards in this title, especially when we get to the high-end.
When it comes to your platform, Dying Light is all about an efficient architecture. Even the Core i3-3220 sustains a minimum frame rate over 30 with maximum details enabled at 1080p. AMD's FX family isn't as successful, though it enables passable performance with minimum drops down to 26 FPS. This could be mitigated if you're willing to dial back detail.
Scary, atmospheric, visually appealing...Dying Light is the full package. It offers an engaging story, memorable landscapes and enough diversion that you'll want to play through it again. I have no problem recommending this game. It doesn't matter if you're looking for a great single-player experience or a co-op romp. You'll get both. Just keep in mind that Dying Light reaches its full potential when the end-game is played with friends online.
