Hey everyone, so I'm testing my GPU(s) today and I'm noticing that my real world testing of the HD 5770 is much lower than reported by apple, and even slightly lower than reported by Barefeats. I'd like to ask everyone here a few questions since I'm not an expert on GPU tech. During a benchmark/Stress test I was running blu-ray and gaming at the same time when I noticed something off on my first gaming run of the 5770. I restarted my machine, let it cool off, and restarted my game (CoD 4MW) and I'm noticing a lot of broken textures.. boxes and walls are black. To shorten this post, after 2 re-installs, complete overhaul of my configuration of the game graphically, nothing has changed.. Is this a driver/firmware issue? is it just 5770 support for CoD? or does it sound like I have a bad card? I'm getting really terrible performance out of this thing..
