Hi Olek,
60-70% looks a bit too high. Is this consumed by a DirectFB-process?
I don't see any direct problems, but I also don't have a G550 to test
myself :)
You also say that video is kinda jerky, which is almost always not
caused by DirectFB, so I get the impression that it has to do with other
bits of your set-up.
Note that DirectFB 1.0.1 is kinda old, 1.2.8 is current.
To check if you are using your Matrox acceleration:
Reconfigure (+compile install) DirectFB with --enable-debug and use the
option --software-warn to print out all occurrences when acceleration is
not being used.

Hi guys,
I am brand-new to directfb, this is my first post to this list (actually there
are two more with similar subject lines, but the email body is missing the
text, Hotmail and Iceweasel don't play nice)
Is it normal that in standard resolution, the CPU utilization is about 60-70%?
Using G550 DVI output to a DLP TV digital input.
Video is somewhat jerky, lacks detail, audio is ahead of video by a fraction of
a second.
For comparison, on the same TV set, the video coming out of an ATSC converter
box, using composite cable is MUCH clearer.
Also, when VLC client is used under X, the CPU utilization drops by about a
half and the video resolution is better.
The VGA output of G550 is not being used.
The CPU is Athlon 1300, 384 MB RAM, SB Live Value soundcard. Motherboard is
Abit K7T.
The app is VDR 1.6.0

How can I configure directfb to take advantage of Matrox acceleration?
Thanks in advance for any helpful information.
Hopelessly confused, Olek.
