Re: [osg-users] Vista/Windows 7 visual problems on resize
On Windows 7 setting the theme to Windows 7 Basic (disabling Aero) fixes all my visual problems on various Windows 7 machines ( not all nVidia). So I think we have to assume that mixing GDI and accelerated OpenGL graphics in the same window is a no-no on both W7 and Vista ( even if GDI is accelerated on W7) -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=23030#23030 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
Re: [osg-users] Vista/Windows 7 visual problems on resize
Hi Gordon, 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) Weird, I've been using Windows 7 since the Beta with nVidia cards and I haven't seen this at all (ever). I've been both developing OSG-based apps and gaming on that machine since then.

You are right. This happens to me quite often.

Re: [osg-users] Vista/Windows 7 visual problems on resize
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.

So this now begs the question.. how to draw a nice "zoom box" using 'pure' OpenGL/OSG since I can't use CRectTracker/GDI -- Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=22966#22966 ___ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org

Re: [osg-users] Vista/Windows 7 visual problems on resize
Hello Andrew, When running on Windows 7/Vista using accelerated graphics, and when resizing a window, an MFC OSG window flashes a lot and "phantom" bits of the window frame are left behind while resizing. The same is seen when using an MFC CRectTracker and TrackRubberBand on the OSG 3D window, the old Rect is not properly erased and the tracks of the box are left behind. This won't help you much, but we haven't seen these kinds of issues with OSG either running its own window or embedded in a QWidget on Windows Vista/7. So perhaps it's a problem with the MFC part of your app. I can't be sure of course, never having used OSG with MFC myself. I hope this additional data point will help...

The same is seen when using an MFC CRectTracker and TrackRubberBand on the OSG 3D window, the old Rect is not properly erased and the tracks of the box are left behind. None of this is seen on XP/XP64 and is not specific to a particular graphics card vendor. If you log onto the Windows 7 machine via RDC ( which causes a default OpenGL software driver to be used) these issues are not visible. This is , I am sure , and old Vista issue , but in our field (CAE) not a single user 'upgraded' to Vista - they are upgrading to W7...
