    If I were AMD, why bother? DX9 can't disappear off the face of the earth soon enough.

    By understanding any issues they can work to prevent bottlenecks in the future.

    AMD's biggest problem is that they didn't account for Frame variance when they built the Crossfire technology. NVIDIA accounted for this with SLI from the ground up, presumably after the disastrous SLI performance variance back in the G80 era, I mean, they over-engineered the hell out of the interconnect, the SLI bridge can sustain 4K frames without so much as hitch while the Crossfire bridge craps itself, considering it (SLI) was designed when 1080p wasn't even common.
    XDMA is a step in the right direction though frame variance is still a massive issue, and sadly, it feels like patchwork instead of a true fix.
    The thing is, the older titles can be rendered at massive FPS so the need for frame pacing is less pronounced since there is little variance in the render speeds to begin with. This is a massive problem at 4K though, even old DX9 titles can suddenly become taxing.
