Panel vs Ogre overlay with text

[Slicky]

I've just started integrating CEGUI at a basic level.

A quick question and observation. I noticed a decent frame rate hit when running demo4 for example. Is this to be expected?

I never noticed much of a hit from the OGRE overlay.

Obviously the CEGUI is much more functional and a real interface so maybe that is the trade off. In that case if there is action on the screen the interface should be kept to a minimum to save fps.

There can be a performance hit, though it's really dependant upon what you're displaying. I might ask what you compared demo 4's performance against, since there is no comparable Ogre demo

Generally, large numbers of widgets with text on them will hurt you the most.

I also must say that there's quite a bit of optimisation that could be done within the CEGUI library; though presently I'm not considering that a priority.

CE.

I didn't have a direct comparison. All I did really was show and hide portions of the CEGUI and observed the frame rate hit.

I still think your system is great and need to learn more about it.
