Anyways, please tell me your findings, if you get the chance to test
this on slower computers with accelerated native graphics. Thanks a
lot!
I'm using Haiku on an old laptop with a 1.6Ghz Pentium IV and an
nVidia Geforce2 Go video card. The bundled nvidia driver doesn't work
on this hardware (http://dev.haiku-os.org/ticket/2641), so I use an
unofficial one (http://web.inter.nl.net/users/be-hold/BeOS/NVdriver/index.html
).
Without the patch, dragging a group of icons in the Tracker or boxes
in Cortex is very slow, the screen is refreshed at less than 2 FPS
(and CPU activity goes to 100%).
Disabling hardware acceleration really improves performance for these
tasks. The only downside I've seen is an increase of CPU load when
moving windows (around 90% versus 20% with HW accel) but it stays very
fluid.
