I’m using JME just for displaying a mesh without any other features of JMonkey. I don’t use audio, physic or collision dection of object but for all that the CPU usage is 11% of my application. If I decrease the frame rate from 60 to 10 then usage goes down to 5% but the picture is jerking.
I don’t make any resource consuming things. I show a mesh and the user can move it. No background, no audio, no explosions
Can I disable any features to save resources? JMonkey takes also a lot time to start the engine.
