Hi Ale,
I don't really understand your comparison. You said you had good
performance before and now it is degraded.
Can you list your previous osg-version which you are comparing too?
Did you change the display driver?
Are you comparing release builds?
Did you change anything in your code?
Can you check display-list performance instead of FBO (I had serious
drops with some NVIDIA driver revisions)?
Hi,
in my application I recently noticed a performance slowdown.
During my tests I always have 60FPS even for complex scenes.
After recent changes I notices that even with empty or very simple scenes frame
rate go up and down mostly from 40FPS to 50FPS
When I enable default on-screen diagnostics (overlay showing frame rate,
rendering time, scene data, ecc.) framerate drop down to 10-20FPS.
So I think this suggest me that it is not directly related to performance of my
code (I did not altered default rendering cycle or did other custom drawing)
I also noticed slow framerate (~10FPS) when I insert around 100 text objects
(osg::Text3D) in the scene.
I use FBO for scene objects and display list for other visual shapes (like
grids, etc)
I have no idea about the way to follow to solve the problem. Do you have some
suggestion?
I am using OSG 3.2.0 with Qt 4.8.4.
Thank you!
Best regards
Ale
