I also use LVM encryption, and mplayer plays 720p at 30 fps just fine |
20 |
with only the integrated Intel graphics and 1 GB of RAM. So, I suspect |
21 |
you are just not using the full potential of your CPU. |
22 |
|
23 |
If you haven't already: grep flags /proc/cpuinfo; add any of the |
24 |
{mmx,mmext,sse,sse2,ssse3,3dnow,3dnowext} flags there along with |
25 |
"custom-cpuopts" to your mplayer line in /etc/portage/package.use; |
26 |
then re-emerge of course. |
27 |
|
28 |
With 4GB if RAM you should probably also set swappiness to a lower |
29 |
value than default. |

|

That's all I can think of for now, good luck! |
