A little note on automatic updates on Video drivers, they are typically quite OLD, take the one for my 8800 the automatic update wanted to place a 9/2007 on my machine yet I have a 4/2008 driver already installed...
Note sure what MS are upto... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jean-Sébastien Guay Sent: Thursday, July 10, 2008 2:56 PM To: OpenSceneGraph Users Subject: [osg-users] Weird driver problems? Hello, We've started seeing something weird on some of our machines, and I'd just like to know if someone else has seen this. These issues started happening today. Setup: Windows XP, GeForce 7800 GTX and 8800 GT, OSG 2.2 and 2.4, two screens in Dual View mode. Issues: 1. Starting osgviewer with any model gives weird geometry problems (large polygons sticking out, see screenshot) 2. Our own apps (still using OSG 2.2) crash on start, when drawing the first frame, and it appears that it crashes in the graphics driver (nvoglnt.dll). The weird thing: switching from Dual View mode to Horizontal Span mode "fixes" both these issues. Our current theory is that some automatic windows update that got installed a day or two ago changed something that caused a new bug related to the graphics driver. Perhaps a threading mode change, or whatever. The people who have disabled automatic updates don't have the problem, so there seems to be a correlation. If that's right, the next NVidia driver version might magically fix it (by working around the new bug). Has anyone else seen this?
