Is it more efficient? Do I need it? I think it is the default. If you see flicker or tearing or other artefacts it's a good idea to have it. > -dr > > Turns on direct rendering.

Generally all these options are from a time 10+ years back when CPUs were much slower and drivers much worse. They could give the extra 5% speed needed to play a video smoothly. It's unlikely there is much point in bothering with any of them nowadays, especially if you do not actually have any issues. _______________________________________________ MPlayer-users mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
