Question

Windows

Hello! I want to use two games in the sand and play them at the same time, for one game I need a mouse, for the other I need another mouse and keyboard, I want to play two games at the same time using the keyboard and mouse without switching between game windows

Answer 1

no way. the focus of the system can only be on one window
you can play by switching between windows

Answer 2

1. There is only one mouse in the system, it is not divided in any way. Just like the keyboard. These devices do not work like joysticks.
2. There is only one input focus, and since there is only one input device (even if there are 200 mice connected), then only the window that is in focus will be controlled, or all windows at the same time if the device is captured by hardware. Those. two or more mice will control one "cursor".
To separate devices in the system, separate software is used. It allows you to initiate two sessions on the device. Like RDP.
