## performance
From my limited testing, this uses about half the CPU performance of Steam's built-in desktop overlay, if running at 60 FPS. Currently the default is 30 FPS which brings that factor to 3-4x. On my machine, the Steam desktop view increases cpu usage by about 100% of a CPU thread (looking only at the `steam` process), while this overlay uses around 25% at 30 FPS and 45% at 60 FPS.
