Project Cars
Video games don't need guns in order to be fun.  With a bevy of racing vehicles, a wide variety of tracks, and a very realistic weather system, Project Cars delivers an impeccable driving experience. It also offers an immersive VR experience, if you have a rig that can handle it—and preferably something other than a keyboard to steer your dream car.

Once again, the mobile GTX 1070 is within hailing distance of the desktop GTX 1070. In this title, the mobile GTX 1070 performs in bettween the desktop GTX 1070 and GTX 1060. Project Cars seems to be pushing the laptop's CPU quite a bit, though, as evidenced by the fuzziness in its frame-time graph.

Even with a large number of cars on the track, Gigabyte's P57X is up to the task here, but our desktop delivers a better gaming experience. The desktop GTX 1070 spent just three seconds past the 16.7 ms mark, versus the much more noticeable 12 seconds of the the mobile GTX 1070. To its credit, the laptop clearly does perform better than the system with the GTX 1060 6GB, which delivered a noticeably less-smooth experience than either of its bigger brothers.

Unplugged performance
As a rule, gaming laptops need to have their power bricks plugged in to an outlet in order for them to perform up to their full potential. Dropping to battery power has an immediate effect on performance.

To assess just how much performance the P57X retains when it isn't plugged into a wall, we ran through our Grand Theft Auto V benchmarks again, but this time on battery. We used the "balanced" power profile in Gigabyte's Smart Manager software utility. We'd have gotten higher numbers from the "High Performance" profile, but if we're trying to simulate gaming on the go, then battery life matters.

In the interest of fairness, we'll skip the usual round of performance graphs. The frame-time graph says it all: you don't want to play Grand Theft Auto V this way. The system's high-end gaming performance is simply hamstrung without a nearby outlet. It produced just 30 FPS and a 95.2 ms 99th-percentile frame time, a far cry from the 15.6 ms it achieved when plugged in. We don't usually go so far as to call a gaming experience unplayable, but that's the only way we can describe the P57X's performance away from a wall socket.

We present these numbers not because there's a laptop out there that does provide a great experience on battery—as far as we know, there isn't—but to remind our readers about what to expect from a gaming laptop. To get the high-flying performance that we saw in our primary benchmark suite, Gigabyte's P57X needs to be plugged in. Consider this machine a gaming-friendly powerhouse that can move between power plugs rather than a way to play Doom on the plane.
