The macro "SMG Holo [But1ch]" for "RUST" can be downloaded and used on any mouse and keyboard.
Installing the macro is very easy in the Keyran program and increases your skill level in RUST, if you follow the
instructions!
Change the FOV parameter to 80 and the sensitivity to 0.75 to adjust the macro. Then try changing the FOV to 90 and the sensitivity to 0.85-0.89 (experiment with tenths for more accurate aiming).
