Maybe you're using the E cursor insted of X cursor? that would make E force
render. Maybe you have also a module that's constantly updating things
(like mem, net, clock or temp)? maybe mplayer is not using gl but software?

I'm using smplayer as an mplayer2 frontend and I have an nvidia card with
binary blobs. CPU had to do lots of cycles until I used vdpau and dri and
that made things a LOT better
