Re: [osg-users] Load balancing on multiple cores

One suggestion that I will offer: build your code in release mode, but do not optimize. Under MSVC, use the following flags: /MD /Zi /Od /Ob0 /RTC1 /D NDEBUG You can add the following CMAKE Option to OSGs CMakeLists.txt to add this type of build as an MSVC option in the configuration manager:

[osg-users] Load balancing on multiple cores

Hello, OSG is a great product and I hope I can tap into the great support you folks offer! I have an Intel Core 2 Duo processor, and I'm running OSG 2.8.2 on Windows XP. And I have VSync turned off, by the way. When I run osgviewerd.exe (debug) I notice that the stats reported are very erratic.

Re: [osg-users] Load balancing on multiple cores

Hi Jesse, I'll let others reply specifically about the threading, but I wanted to react to one part of your post: When I run osgviewerd.exe (debug) I notice that the stats reported are very erratic. Never do any performance testing in debug, especially using Visual C++! An erratic frame

Re: [osg-users] Load balancing on multiple cores

Hi J-S, Never do any performance testing in debug, especially using Visual C++! An erratic frame rate and stats is exactly what I have come to expect in debug. Visual C++ and its iterator and other debugging facilities really get in the way and make the stats useless. If you get the

Re: [osg-users] Load balancing on multiple cores

Hi Robert, Thanks for the response. We'll if VisualStudio's debug performance is too bad to develop with routinely avoid using debug unless you actually need to do debugging, or pick a better compiler or see if you can tweak compiler options to avoid the pitfalls of VisualStudio. I do
