I'm surprised MW2 has an issue with Crossfire, mine's crossfired without any issues whatsoever (4890's 16x each).ĭo you know if your PCI-E's are both 16x or 8x, or maybe it's being bottlenecked at 16x/4x? (had a MB that did that).Īnyways, I have a similar issue with Serious Sam HD's. Yea this is a few months old, but it's relevant.
