currently in GameOS there a homebrew called showtime. Using FFMPG can play 720p H264 smooth. I have not tried 1080p...
so maybe with this new CFW OtherOS have same privilage as gameOS, linux can run faster. Like using hardware acceleration rather than using software for the linux desktop, video and so on.
Previously on PS3, linux only running in software mode,
then someone do a hack to get RSX access, but then blocked in FW update.
so now with this CFW maybe linux can run again with RSX and running with acceleration using something like glfx, rendering 3D using RSX, or something.
like in Ubuntu when not install ATi GPU driver, it only run in software. Then after driver install, it can run in glfx mode. (sorry if wrong, been long time since last time using linux)
