RE: [Plib-devel] Indirect rendering contexts in PW

[Fay J. F C. AAC/W. <joh...@eg...>]

The screen savers are somewhat slower (I assume they're largely
OpenGL-based) but the terminal windows that I use don't seem to have any
performance hit.

I kinda doubt there is anything we can do about that.

If you are getting a direct rendering context some of the time - then our
code is clearly requesting a direct rendering context if one is available.

When we don't get one, then something in the GLX stuff is saying that we
can't have one.  Dunno why that would be - but it's a driver issue.

Do things run more slowly in dual-head mode?
