I apologize if this issue has been covered before.
I've tried searching for a solution for the past 3 days and nothing yet.
I've also tried searching the forums here but it won't let me get past the stupid "image verification" code.
I'm runing 2 radeon hd4870 1gb cards in crossfire with the latest catalyst software (9.3). In CCC, crossfireX is checkmarked. During gameplay, it shows the crossfire icon in the upper right hand corner.
***Here's my problem***
In GTA IV under graphics settings, it says i only have "1024 MB" of video memory, when i really have 2 cards of 1GB memory installed. ***? Is crossfire really working? There doesn't seem to be a performance increase with both installed. Actually i've noticed a decrease compared with only one installed. Does GTA IV recognize crossfire?
Under GPU-Z it says crossfire enabled (unsure for vista 64). I have win vista 64 ultimate. Unsure......? I was under the impression with 2 1GB cards crossfired that I would have 2GB of video memory!!!!!
Excuse my newbness. This is my first time crossfiring and so far i'm disappointed with it.
