Hi Juan and Robert, Thanks for the help, I compiled the pbuffertest code, I had to add this to the header section to make it work (i'm using osg 2.8.3)
Code: #include <osg/Notify> #define OSG_NOTICE OSG_NOTIFY_1(osg::NOTICE) #define OSG_NOTIFY_1(level) if (osg::isNotifyEnabled(level)) osg::notify(level) pbuffertest -w works and makes 100 frames (the viewer window is shortly visible). pbuffertest -f 1 doesn't work and produces the known error: Code: Frame : PixelBufferWin32::makeCurrentImplementation, wglMakeCurrent error: 0Die angeforderte Ressource wird bereits verwendet. Test Ecrormoprl:e Otpeedn. GL version test failed, requires valid graphics context. (btw, exchanging the OSG_NOTICE with printf gives the correct "Test completed.\nError: OpenGL version test failed, requires valid graphics context." instead of "Test Ecrormoprl:e Otpeedn...." for pbuffertest.exe -f 1) I installed GPU-Z but couldn't find the OpenGL Extension Information. I installed the OpenGL Extensions Viewer (http://www.realtech-vr.com/glview/download.html). It confirms that among others WGL_ARB_pbuffer WGL_ARB_pixel_format WGL_ARB_pixel_format are supported by my nVidia Quadro FX 580 (see screenshot). Because it sounded like a possible fix, I defined the environment variable OSG_WIN32_NV_MULTIMON_MULTITHREAD_WORKAROUND to ON, but that changed nothing. As far as my little knowledge goes, I think that the bug is in the osg code.
