This feature turns on and consumes 100% of the disk for a moment and the GPU usage is falling at the same time, which is noted as a decrease in FPS. Contrary to appearances, the 920MX is not such a weak card, as some write, after all, this version of the laptop has gddr5, which gives a perceived difference from ddr4. Also check with HW info if you have a processor working in balanced mode (the frequency should change depending on your needs). For me, on a connected power supply, despite the balanced mode setting, the processor was constantly running at maximum frequency.
