Yeah, and I get that. However, Dirt2 released long before the signifigant driver change...before this change, Crossfire scaling didn't seem to have this bottleneck. So, with that in mind, any review out there, that kinda looks at this issue...was done prior to that change in the drivers, and as such, must be verified, before being accepted as fact. The same is true every month, when a new driver comes out...old reviews may not have accurate data....but because the changes were so great...I truly think that this specific period of time, when the driver was changed, is very important. And as I said, he's running a single card, so the situation is OK. The rest is MailMan trolling, IMHO, because he didn''t like my answer. He ignored that I made the stipulation, that it seems once these 5-D shaders are in greater numbers than 1600, AMD cpus have issues feeding the cards data. Robert, with his 3c4850, is @ 2400 shaders, so runs into the same situation that I describe. And yes, as I've said before, at stock, you bet Intel runs into the same problem...for some reason not as quickly. And because of this, I largely blame the driver alone...becuase, as erocker suggests here...things weren't so bad before.... I'm NOT singling out AMD cpus here....which is where you seem headed...I really think it has nothing to do with anything other than the VGA driver. BUt agian, I am NOT 100% sure on this. Robert is looking for a list of these games that have these problems...WITH STOCK CPUS. My testing, so far, says ALL APPS have issues with Crossfire scaling...but not all are affected so much that they drop below 60FPS...hence me telling him that it's giong to take some time before I can identify each one. Everyone brings up good points that can help overcome this problem, but none of them are actually answering Robert's question. The response "Overclock, and it goes away" isn't a proper answer. The response "I have a single card, and no issues", doesn't apply. And Robert, please feel free to correct me here if I am wrong in any of this.
