Game Mode is great when you want to slightly bring down the power consumption of your rig to conserve power, but still, want enough juice to play games at a decent output.
Game Mode: this is the mid-settings of your GPU that allow for decent performance without taxing your computer too much. Take note that the graphic card and PC fans will be running on maximum with this setting. This includes achieving 4k resolutions of graphics of higher framerates. OC Mode removes the limit of your GPU to give you a full gaming experience of many software titles. MSI Gaming App gives you full control over the performance of your graphic card.
