Thanks for testing.

Thanks again. There's a trade-off here between rendering performance (software rending vs. hardware acceleration) and network latency (just sending the image vs. sending lots of OpenGL commands (some of which might be synchronous, requiring a round-trip for the response)) So, the short answer is, you should try both and see which performs best :-) Provided your server isn't on the moon, I would guess that ParaView would behave better with indirect but accelerated rendering, but that's just speculation. I'm not sure of the reasoning for mesa making direct using software rendering the default for remote clients, I'm not sure exactly what kind of client it helps with. Possibly the UG should have some words discussing this issue. -- Jon TURNEY Volunteer Cygwin/X X Server maintainer -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
