Hi Ulrich, Sorry about the lack of system specs. I'm actually using an NVIDIA 7950 GT with the latest drivers. Some other system specs: AMD FX-62 Dual-Core Vista 64-bit If it matters any, I'm using the SVN build of OSG. Thanks for the help. Regards, Kim. Date: Thu, 17

Hi Kim, The high CPU utilization in this case clearly isn't the OSG, but the drivers/OS. Try a different OS/drivers. Also once you home in what combination causes the high CPU utilization go pester NVidia about there driver doing a spinlock. Robert. On Thu, Sep 17, 2009 at 6:08 AM, Kim Cheung

[osg-users] Error Messages

Hello, osg use the std::cerr for the error output and i think it is not so good. I get the error in the console every time. Nvidie PhysX use a class NXUserOutputStream. It is a nice idea for osg, maybe? Cheers, Martin ___ osg-users mailing list

Hi Nils, To get events back from underlying browser it would probably be best to go with using QWebKit based embedded browser rather than the existing gecko/llmozlib plugin that I wrote last year. QWebKit is far more amenable to getting various events back, although not perfect it's turned out
