getting framerate outside of debug overlay.

How do i get the framerate without using the debug overlay? When i have many objects on the screen the overlay takes up alot of processing power which throw off my framerates.

Use the default Ogre debugging from the code provided by the tutorials.

Here's one from wiki online:
http://www.ogre3d.org/wiki/index.php/Og ... cation_cpp

Goto line:
void OgreApplication::updateStats()

And line:
bool OgreApplication::frameEnded(const FrameEvent& evt)

the overlay takes up alot of processing power which throw off my framerates.Really?!

try this:

www.fraps.com

well i was thinking more along the lines of actually having a value of fps in my program because i eventually want to output it to a file so i can see what is taking processing power up.

edit: ah im looking at the wiki now

Ogre::RenderWindow::getLastFPS()
This inside the FrameListener should work too.
1 / evt.timeSinceLastFrame

why doesn't this work:
float fps=Ogre::RenderWindow::getLastFPS();

1>error C2352: 'Ogre::RenderTarget::getLastFPS' : illegal call of non-static member function
1> : see declaration of 'Ogre::RenderTarget::getLastFPS'

Because there can be more than one render window so it's not a singleton.

It goes:

mWindow->getLastFPS()

It goes:

mWindow->getLastFPS()

thank you =)
