The Xtreme Gaming Engine
Gigabyte's included software utility for monitoring and tuning the GTX 1080 Xtreme Gaming is called the Xtreme Gaming Engine. While the app does have a rather silly skin on it to match the Xtreme Gaming card's wild looks, it at least doesn't sacrifice usability to the flashy facade.

Upon launching the app, users are greeted with a picture of the card being monitored. To nobody's surprise, that's a GTX 1080 Xtreme Gaming in the case of this review. Gigabyte's interface displays multiple frames to account for multi-GPU systems, although the six open spaces here seem a little optimistic given Nvidia's recent move to support dual-GPU SLI exclusively.

After the user chooses a card, the XGE displays all of its vitals at a glance. It also provides big orange sliders for modifying core and memory clock offsets, GPU voltage, power limits, and temperature limits. Users can create a seemingly arbitrary number of tuning profiles using the drop-down in the upper left.

The somewhat-confusingly-named Advanced OC section actually controls this GTX 1080's baked-in clock profiles, too. We get the default "Gaming Mode," a slightly more aggressive "OC Mode," and a slightly down-clocked "Eco Mode."

If the pre-baked profiles aren't to one's taste, the app also lets users apply a linear offset to the card's voltage-and-frequency scaling curve or use the GPU Boost 3.0 features in Pascal to tweak clock speeds at a variety of voltage levels. We won't be doing that kind of tweaking today, but more ambitious overclockers can sleep soundly knowing that the option is there.

The "Fan" section of the app provides control over three baked-in fan profiles, as well as options for setting fixed fan speeds or a custom fan curve.

Finally, the "LED" section lets owners change the lighting color of the Xtreme Gaming logo on the side of the card and the four light pipes above the middle fan. These LEDs behave as one zone, so picking a color is an all-or-nothing affair. Along with the usual solid color mode, Gigabyte includes "breathing," "flashing," and "dual flashing" styles, plus a "variable brightness" mode that can (in theory) change the brightness of the card's LEDs in response to inputs like CPU or GPU temperatures.
