Re: Working setup with two pci-e (ludovic pollet)

[Ludovic P. <pl...@fr...>]

The interresting part is cpu usage of X11 process. In all case, with xv,=20
mplayer only has to copy data to a Xshm. It doesn't directly hit the=20
hardware... X11 then has to copy these data into the memory of the graphi=
cs=20
cards and then instruct the GPU to blit/overlay it on screen...

So what is X11 cpu usage in you case ?

Ludovic
