## What it is
sys-clk is a Nintendo Switch homebrew system module that lets users set custom CPU, GPU, and memory clock speeds per application and per docked/handheld/charging state. It includes a manager app for hbmenu and a Tesla overlay for adjusting clocks from anywhere.

## Use cases
- overclock cpu gpu mem clocks on nintendo switch for smoother game framerates
- set per-game clock profiles by title id
- underclock the switch to reduce heat and battery drain
- apply different clocks when docked vs handheld vs charging
- log clock speeds and temperatures to csv for performance analysis
- adjust clocks in-game via tesla overlay menu

## When to choose
- you run Atmosphère CFW on a modded Switch and want per-title clock control
- you need to fix framerate dips in specific games like Zelda BOTW
- you want to monitor clocks and temperatures while gaming

## When to avoid
- you have an unmodded or stock Nintendo Switch
- you are not comfortable installing homebrew system modules
- you need overclocking on platforms other than the Switch
