Actually, as soon as Rebel-Tiger is loaded, you have 2 programs running: the GUI
and the engine. OK, they are not 2 different programs, the correct term is
"processes", or "threads".
Windows is in charge of the control of these processes. It detects when one is
idle, and in this case let the other one take 100% of the CPU. Generally, the
GUI is idle, so the engine takes 100% of the computing power.
However, there is a special time when the 2 processes are not idle. It's when
you do a move and the engine has to start searching. At that moment, the GUI has
to execute several tasks, such as repainting some areas of the screen. The
engine, simultaneaously, starts thinking.
It is interesting to give a higher priority to the engine when you use fast time
controls (game in 3 minutes or faster) or a very slow computer (a 486 for
example).
In this case I have noticed that the NPS is higher with the engine on high
priority.
At long time controls on a fast computer, it will make no difference.
