I've seen similar things with my current laptop, which runs AMD/ATI
hardware. Before, when using OSS drivers, I had a high frame rate, but
flaky video, after installing the non-DFSG drivers from ATI the video
has become more stable but the refresh rate has dropped to 60Hz.
Further investigation resulted in a page (URL lost...) that stated that
the new drivers are synching to the monitor's refresh rate, which makes
sense. Why refresh the frame buffer at 2074FPS if the monitor is
refreshing at 60Hz? I'm not sure how definitive it is, but it would be
interesting to see what happens to the refresh rate when driving a more
capable monitor... If plugging in a monitor capable of 75Hz at the
current resolution causes glxinfo to report 75Hz, then I'd say there's
something to the "theory".
