I saw in another thread (http://forums.java.net/jive/thread.jspa?threadID=39219&tstart=0) that some Intel hardware is disabled. Dmitri said, "Indeed, currently hw accelerated pipeline is disabled on Intel adapters due to drivers problems."

Can you say a bit more about this - is it likely to be fixed in future releases of Java or will it need Intel to issue new drivers. Is there a list of which adapters are affected?

Hi Peter,

yes, currently the D3D pipeline is disabled on all Intel
adapters. You would only want to enable it on the latest
adapters anyway (G965, or X3xxx family) since earlier
ones (915) don't have hw transforms and lighting anyway
which means they're very slow.

The G965 are OK performance-wise (and by OK I mean they
show performance similar to 4 years old low end Nvidia
board), but the thing blocking us from enabling the
pipeline is some severe driver stability bugs (like
rebooting the system on heavy load), and rendering
quality issues.

We have filed the bugs with Intel, they're working on
them but at this point there's no ETA for the fix.

Even when they do fix it, then we would only enable
the pipeline conditionally for this specific driver,
and after some extensive testing, of course.

Thanks,
Dmitri
