Grand Theft Auto V
We used a 1,920 x 1,080 resolution (our usual 1,920 x 1,200 wasn't available) and the GTA V built-in benchmark set to maximum possible quality settings to offer an intense challenge for the gaming hardware while also making playable frame rates a possibility.
However, the GTX960M's 2GB of memory meant we couldn't set every setting to Very High, and had to leave quite a few of them on merely High. We used FRAPS to record the frame rates of the last portion of the benchmark, where a jet flies across the city followed by a truck ploughing into a petrol tanker.
Here again the Dell falls notably behind the MSI GS40 6QE Phantom competition on average. It's borderline playable, but won't be comfortable all the time.
As with Tomb Raider, we thought we should try 4K with GTA as well. However, you will see from the setup that we had to ramp down most of the visual quality settings to get the game to run at 4K within the 2GB of memory afforded by the NVIDIA GTX960M graphics.
Thanks to the vastly reduced quality settings, the game is actually more playable at 4K than it was Full HD. But a lot of quality has been traded for resolution, making this a far from optimal gaming experience.
@James Morris, did Dell confirm support for eGPU enclosures through that Thunderbolt 3.0 port? Merely having the port isn’t enough, system BIOS level support is also needed for it work.
