the demo doesnt support crossfire or sli
post #3 of 11
my best guess is..the demo is in essence a console port and does not support crossfire/SLI..not saying the PC version in the future wont... but this way is less work for crytek

Crossfire is supported through drivers, that's why there is a new one every month, with crossfire profile updates. The game isn't even released so it isn't a fail, yet.

all i can say is WOW , how things have changed for crysis ... Cant even play with multi gpu's i would never of thought it would of got this bad ..

no dx11 , no sli or cfire support thats just rubbish .. i was expecting more from a company that made the worlds best fps 4 years ago !!! crysis warhead got dx9 and dx10 , not much difference between the 2 but adding tesselation to crysis 2 would make it look stunning ...

i guess crytek arent bothered ? cos its very possible ... DiRT 2 is in dx11 for god sake , even s.t.a.l.k.e.r and some other games no1 cares about .

This game had high expectations , and it didnt meet them . Unfortunatly , people are saying its only a demo .. dont be suprised if nothing has changed in the full release bcos im highly doubting it .

It is a good game though after saying all that , even in dx9 it looks incredible on hardcore playing at 60fps 1080p.

How do you fit two Crossfire bridges onto HD5770s?

Or do you mean you tried two different bridges?

Edit: Googled it and found the answer, nevermind.

Have you tried using just one bridge?
