IS Boxer renders everything at the size of the large window.
It then scales the smaller windows down.

Because they are rendered at the full size, the PiP swap is instant.
And the mouse broadcastings is very precise.

But your system has to process all five windows, as if they were each maximum size.
A bit more of a strain on resources, although virtual configuration files let you adjust settings on a per toon basis, which can help some.




To disable keymaps, open IS Boxer Toolkit. Click on Control Keymaps on the top. The first keymap on the left is "Activate Maps".

Whatever hotkey is set, will turn them on and off, as this is a two-step macro.

I've got mine changed from the default key to the M3 light key on my G15, along with a light on action when they're enabled and a light off action when they're disabled.
