Does fglrx support render acceleration?

[Variant]

Apparently the lack of render acceleration is the main culprit behind my Xorg (Fedora 7) 2D desktop (no beryl/compiz or compositing going on) just not being that "snappy" -- compared to an NVidia card or the same Radeon in Windows.

I have a 9800XT.

Does anyone know if the fglrx supports RENDER acceleration? ("RenderAccel")

The open source driver does not support it on the 9500/9700 cards and above unfortunately.

Thanks.

the oss should support it according to the official blog
(see: http://tirdc.livejournal.com/ )
the fglrx supports it too, including aiglx from the 8.42.3 release.
in older releases for compiz/beryl you would have had to use xgl.
to enable rendering in xorg use:

Option "RenderAccel" "true"

in your SectionDevice
and

Section "Extensions"
Option "DAMAGE" "true"
Option "RENDER" "true"
Option "Composite" "Enable"
EndSection

this things have been covered a lot in the 8.42 thread in this forum and get out if you take the time to make a search on this forum.

from the last 2 releases of the fglrx (8.41.7 and 8.42.3) the performance of the ati boards aren't too far away from windows and from nvidia boards. for a comparison see this article:
http://www.phoronix.com/scan.php?page=article&item=897&num=1
where the fglrx 8.42.3 with a hd2900 performs about 20% better than the driver in windows vista.

Render is there by default and the option RenderAccel is not needed/used at all.


Most of such info is in your Xorg.0.log:

(II) Initializing built-in extension RENDER
(WW) fglrx(0): Option "RenderAccel" is not used

I would never use RENDER true, because thats for emulation only. Speed is extra low.
