it's not idle. something is re-rendering continually. are you on up-to-date efl?

you enabled opengl AND texture-from-pixmap? i've had e comp working silky
smooth on a gf6600 with 3520x1200 of pixels. games pay the price of another
buffer copy - that's it. nb i did add some options for nvidia's driver:
Option "TripleBuffer" "True"
Option "Coolbits" "7"
Option "UseEvents" "True"
Option "OnDemandVBlankInterrupts" "True"
