However, there is a sliver of truth here. Some older DRM systems (like SecuROM or older Denuvo versions) were incredibly inefficient. They would constantly check the license in the background, eating up 5-15% of your CPU cycles. Removing that DRM via a crack sometimes resulted in a marginal performance gain (2-5 FPS). But against a game that runs at 15 FPS on low settings, an extra 2 FPS is still unplayable.
