In this update I've added a handy thing named performance presets.

Performance presets is a quick and easy way to optimize Vivaldi. All you need to do is change one line in config.yml. Change the PerformancePreset key to one of the five existing presets (VERY_LOW, LOW, BALANCED, HIGH, ULTRA) and see what happens.
