I don't think this applies to Windows 7 as it DOES have accelerated GDI un-like Vista
But windows 7 and NVIDIA drivers fails and dies a lot for both Opengl and Direct X, and that causes issues even though Window 7 recovers and restarts the driver is sucks up resources leading slowdowns and crashes You see a lot of nvlddmkm.sys problems in the event logs ( there's a lot folks suffering this) Gordon Tomlinson Product Manager 3d Technology & Future Products Overwatch(r) An Operating Unit of Textron Systems -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Andrew Cunningham Sent: Wednesday, January 20, 2010 9:41 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] Vista/Windows 7 visual problems on resize I think this answers my question , at least regarding trying to use CRectTracker. >From http://www.opengl.org/pipeline/article/vol003_7/ "GDI is no longer hardware-accelerated, but instead rendered to system memory using the CPU. That rendering is later composed on a 3D surface in order to be shown on the desktop. The graphics hardware video driver is no longer involved in GDI rendering, which means that mixing GDI and accelerated 3D rendering in the same window is likely to produce corruption like stale or blanked 3D rendering, trails, etc. Using Microsoft's OpenGL software rendering (the first item in the four OpenGL implementations) will achieve GDI compatibility, but at the expense of rendering speed and lack of modern features." So no mixing of GDI and accelerated 3D into the same window... The problem with resizing is obviously related. ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=22965#22965 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.or g _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
