Just to follow up, Mark, I've upgraded drivers and tested with no changes. I am, however, running a 7800 card, not the 8800.
I've just checked in a change that disables both vsync and testVSync for RenderSurface_X11. In light of the fact that card manufacturers are now putting a cpu block in SwapBuffers, this call is now redundant. I'm still quite opposed to this because of the detrimental effect this has on single threaded applications with multiple windows/contexts. But whatcha gonna do? -don On 1/5/07, Mark Acosta <[EMAIL PROTECTED]> wrote:
Yeah, I noticed that. Something is definitely not right there. Now that the 1.0-9746 drivers are released, maybe someone with something other than an 8800 nvidia card can try running a Producer app and let us know if it hangs in the same spot. I wonder if it's an 8800 issue or an issue for all nvidia cards.

Here's an interesting question. Why is NodeVisitor being called from libGLcore ? That looks suspiciously like a corrupt function pointer or something. -don On 1/5/07, Chuck Sembroski <[EMAIL PROTECTED]> wrote: > > Hi all, > > I just wanted to relay this info. > > On nVidia' s 8800 GTX running the nVidia driver 97.44 we see Producer > hang s. > > The offending code is in RenderSurface_X11.cpp in the call to > testVSync(). > > Has anyone else seen this behavior.
