My skylake (i3-6100U) system drops frames when watching x265 movies (in mpv |
| 2 |
and kodi), with all cores at 100% CPU. I've re-run through |
| 3 |
https://wiki.gentoo.org/wiki/Intel and tried changing from the intel driver |
| 4 |
to modsetting, and it appears to use less CPU for x264 at least. Still |
| 5 |
maxed out for x265 so I cant tell if there's a difference for that. |
| 6 |
|
| 7 |
I'm going through the USE flags for kodi, mpv and ffmpeg, which flags are |
| 8 |
the most important? Is there some way to run a simple movie playback |
| 9 |
benchmark to assess the impact of changes? |
