Much better site to test on for sure. Took a full 10 seconds to load fully, even on Fios. Now that it's fully loaded, I'm scrolling up and down both fast and slow, and I see no lag at all. Zooming in on any particular spot is fine as well. Scrolling while zoomed in is fine as well. And I mean the scrolling is very smooth.
System Panel is still showing <25% CPU.
I think the stutter you guys are seeing is a problem with the stock Evo, and that stutter is clearly seen in the video in my sig that I made to demonstrate the real effects of the FPS uncap. The stutter is not the choppiness of the 30FPS; rather, they occur sporadically on the stock evo. Doesn't matter what you're scrolling, browser, or Sense. The stutter is there. Custom kernel with the FPS fix DOES remove these sporadic stutters, also demonstrated in my video.
I may have to post a video of scrolling and zooming on engadget if there's still any doubt. Regardless, even if the Epic can scroll better than the Evo on a fully loaded page, I would not give it much weight in determining which phone to buy.
I would be curious what the FPS readings are during the 3D portions of quadrant on a stock epic, though.
