Company Of Heroes DX10
We’ve excluded Radeon 4870 CrossFire results from this graph, as we couldn’t get the cards to completely scale in CoH. It’s not that the cards weren’t scaling under CrossFire, they certainly were, but their scaling performance was barely an improvement over the 4850 CrossFire setup. We’re confident we weren’t CPU-bound either, as we saw this occur under both 4xAA and 8xAA with max game settings. No matter what we tried the cards were only a couple of percentage points faster than 4850 CrossFire. We’re going to look into the issue further, we have a feeling we probably ran into a snag with the cards under Vista. CoH was the only game that exhibited this behavior with the 4870’s running CrossFire so we’re confident it was an isolated incident.
