recent testing shows a few things
some games like being forced to 1 core or some prefer letting windows choose.
AH doesnt seem to mind letting windows do the work.
however im encoding a DivX movie right now, which is defaulted to core0 only when installed. It can use multiproccessing but not much improvement nor is it supported.
So anyway i left it at default core 0 only, however MSFS 2004 (FS9) doesnt seem to be able to choose which core to use correctly (its setup to use either by default) and i get 9fps with almost no cpu useage on second core
so ive forced Divx to core0 and forced FS9 to core1 and its running fine...
odd that some (most) games dont seem to mind yet a MS game does?
