there's a few call of duty clients that support cg_fovscale as well as cg_fov which scales all fov's including zoom. the remaining call of duty clients are:
-plutonium (https://plutonium.pw) for modern warfare 3, black ops 1, black ops 2, and world at war
-boiii (https://reactiongaming.us/community/threads/how-to-play-black-ops-3-with-the-boiii-client-updated-june-24-2023.1971/ for tutorial on how to get running) for black ops 3
-h1 mod (https://github.com/h1-mod/h1-mod) for modern warfare remastered
would it be possible to add support for this command in the calculator? most people use this command instead of cg_fov or in-menu fov due to better support.
