ok. well. the ghosting issue is not a problem for me either. =)
i´ve not fixed the problem yet, so i´m not to any help.
but i want to know one thing... do you experience big black vertical lines flashing over the screen. i don´t know if this is related to the rainboweffect, but it usually happened about the same time for me.
also. how does the rainboweffect behave?
can you sometimes play for a little longer before it appears? and can it suddenly dissapear again and then appear and so on... ?
when i first got my computer the problem started at exactly the same time always, always when i entered a specific room in max payne 2.
then, after fiddling some with the drivers it all became more random. i could sometimes play for an hour before it appeared, and sometimes it appeared instantly.
and then, after some more fiddling around i started to get the vertical black lines issue (that also appeared sporadically in windows, without any games running).
and then i stopped playing games, and sent it to alienware.
