I have a multiple display system with an NVIDIA 8800 GT (driver version 181.20) that has performance problems when I use FBOs (see attached test case, modified from osgviewer.cpp). My draw times jump from about 7 milliseconds to 14, and my GPU times jump from less than 1ms to 7ms.
The problem goes away when I switch from "Multiple display performance mode" to "Single display performance mode" in the NVIDIA Control Panel, so this looks like a driver bug, but I was wondering if anyone was aware of this problem and any ways around it (I didn't find any discussion of such a bug via google)? I'm running on Windows MSVC 2005 using OSG svn rev 10273. -- Bryan Thrall FlightSafety International [email protected]
