beta versions had the "dual-fb" | "page flipping frame buffer" whatever and graphics were really fast, but it's now turned off because it caused random crashes.

See this video, how smoothly windows move. page-flippingwhatever thing is turned on, and surprisinly it crahes at the end. http://video.google.com/videoplay?do...xCQ&q=nirdroid

in all the later videos, with pageflipping turned off some graphics are jerky

(this does propably ansver your question, i have no idea if the graphics were any faster than in maemo, or if it had opengl)

btw, early versions of Mer had Xorg and software accelerated OpenGL (slow)
