Q: Why is the current X850 CrossFire limited to 1600x1200 resolution at low refresh rates- would a better chip used for compositing engine helped?
A: The limitation is due to the DVI link because DVI has a certain amount of bandwidth which is at 165MHz x 8-bit. There’s a certain amount of bandwidth there and we wanna use that bandwidth to communicate between the two cards. (Since) one card is not opened for display so we can use all of that bandwidth dedicated to pair those (cards).
