Maybe your drivers are faking hardware support for certain overlays.
My card does this, and the result is this:

MPlayer does no conversion, decodes YV12 to the vo module.
Your drivers convert in software and do it very slowly.
You see lots of CPU time wasted.

If you use -vf noformat=yv12 then YV12 is disallowed and converted
by MPlayer (much more efficiently) to another format that truly is
supported by your hardware.  CPU usage drops from 90% to 42% on my
system.
