If a program is running a 3D process, you will not be able to switch Hybrid graphics modes unless you first close the "blocking" program.
You can override the blocking action of some programs if you encounter the following situations:
A certain program prevents you from switching Hybrid graphics modes, but you want to test whether the program runs fine anyway.
In this case, you can specify that the program not prevent you from switching Hybrid graphics modes when it is running.
Note: Some programs are specifically managed by the system to prevent you from switching Hybrid graphics modes. The blocking action of these programs cannot be changed.
A certain program does not prevent you from switching Hybrid graphics modes, yet becomes unstable or crashes when you do so.
In this case, you can specify that the program prevent you from switching Hybrid graphics modes when it is running.
