Crossfire + window mode

I am running 2xATI HD5770 in crossfire mode and when in window mode, the game only uses 1 card and maxes it out. Switch to full screen sorts this out, however is this a driver problem, or is it a game problem?

I am gonna guess game problem as WOW runs fine in window mode with both cards purring away happily. Can anyone confirm?

If game issue, any eta on it getting looked into devs?

    I was having the same problem on my Radeon 4800 series cards until I ran it in full screen.

    Hopefully it'll be fixed soon but atleast it works somewhat.

    well thats kinda odd as ATI have stated multiple times that crossfire does not work in windowed mode at all, however in regards to WoW it may seem like it is using both cards but i am guessing it is not as WoW is not exactly a gpu intensive game and can be maxxed on some older gpu's from 3-4 years ago, i could try and look up a like to this for you though if the search function on the ATI forums actually worked.

    also on a side note i too have crossfire (2 hd4870's 1gb) running in my pc and have personally never seen any of my games use 2 gpu's in windowed mode only when i run game in full screen do i see them both being used.
