Yes, but what about texture compression? And accelerated direct rendering in 2d?
For example Ive noticed a good improvement with mplayer using xv instead of x11 as an output driver If you have sourcs for further reference Im generally interested, thanks 2008/7/7 Daniel Mons <[EMAIL PROTECTED]>: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > Null Ack wrote: > | Martin you appear to not be familiar with 2d acceleration on Linux? > | > > You appear not to be familiar with exactly what "2D acceleration" is, > how generic it is, and how little it has to do with the actual > application level number crunching. > > 2D acceleration has been around since the days of PCI graphics with > 256KB frame buffers, and yes, even in Linux (or more correctly, XFree86 > and today Xorg).
