Win32 has 31 (*) levels for priorities where a programer should stick to the predefined levels. If two engines run with the same priority level they would get equal cpu usage. I have not done too many games with bringer but it seems that he force himself to the front and therby get a boost if the user have decided that he will give a boost for foreground programs. If I remember right so do glc run the search in another thread than the main thread so playing a ponder on game on a gui that alter the priority is pointless. Odd Gunnar (*) From my memory so the number could be slightly different.
