Low FPS in SceneComposer

Troubleshooting SDK
1

I’m trying to use jMonkeyEngine SDK in order to create a scene. But it turns out that OpenGL window gives me only 2-4 FPS even when the scene is completely empty. However the games, that I write using jMonkeyEngine, have 50-60 FPS. What can I do in order to increase OpenGL Window’s FPS?

jMonkeyEngine SDK’s about window:
Product Version: jMonkeyEngine SDK 3.0RC2
Java: 1.7.0_09; Java HotSpot™ Server VM 23.5-b02
System: Linux version 3.5.0-25-generic running on i386; UTF-8; en_US (jmonkeyplatform)

My OS is Linux Ubuntu 12.10.

Thanks for your help in advance!

Try switching off Compiz and other 3d desktop effects.

Also, you can check my simple world editor. It works with j3o models. And it saves to j3o scene…

It seems, that I have no desktop effects enabled… Can I create terrains (height maps, alpha maps for them) with your World Editor?

Terrain can be made only with SDK. But you can save it to j3o and load to the world editor.
But it seems you will not be able to make a terrain as you have only 2 fps…
