    On fglrx, there were huge latencies incurred within the graphics driver for certain operations, so you'd get a "micro-hang" of the entire system (kernel, audio, mouse, everything) several times per second. It'd render a small group of frames, then seize up for a couple msec, then render another group of frames (the groups appear to be about 15 frames big). This basically destroyed the audio because not even pulseaudio's timer-based scheduling can deal with a situation where ALSA randomly gets blocked for ~50ms for four intervals per second.
    My friend noticed this micro lagging on Windows when he was playing Skyrim. He said this only occurs with latest Catalyst drivers.
