Here is an
old email I found. It states that opengl apps
do not use
hardware acceleration unless direct rendering is
used ( with
the exception of the closed source nvidia
drivers).
Is this
still the case?
I looked in
the 4.1.0 docs, and could not find any place
where this
information would live. There was a section that
stated that
hardware acceleration was used on specific
hardware,
but it did not say whether it was 2d or 3d. (I am
interested
in opengl only, and also linux only.)
If it is
true, then is it likely to change in the near future?
Where would
I found this information?
I looked at
the mesa3d.sourceforge.net pages, but could not
find
anything there either.
Thanks in
advance,

NVidia's binary drivers for 4.x do as well. Sorry I didn't point this out in the first place.

There is no difference as far as the client is concerned. The only difference is speed. There is a difference between direct and indirect rendering (the former can't take place over the network obviously), and the DRI currently concentrates on the direct rendering case (hence the name ;) Michel |
