So, correct me if I'm wrong here, if you set the chess (or/and all the other
apps except the *serious* computation prg) at priority -1, how long do you
have to wait before the chess game makes its move or the tetris block makes
1 move down? ...not until the 20 minutes computations is finished? Or do
you have to take a coffee between each move (for tetris)? 
So what's the point?

                                              ^^^^^
Does the Chess prg set at priority -1 satisfy you?
