Hmm. It's a bit hard to judge subjective feelings, especially when you
have expectations of improvement, but yes, I think this does improve
the the interactive feel when scroll-wheeling around in firefox or
chrome.
So on the whole I'd trust the actual latency benchmark numbers more,
but I _think_ it does translate into actually feeling better too.
