BulletSim Physics Engine

7 years 7 months ago - 7 years 7 months ago #1338 by DJ Devil
I am working on lowering the Ram Usage of OpenSim one of my Results lead me to the Physics Engine apparently BulletSim uses less then the default ODE has anyone tried this, and what are the advantages / what is missing

And does anyone know how to Set It up since i get a crash on startup when i try to run OpenSim

Hey DJ we did try BulletSim a while back and it did reduce our ram usage, sad to say our experience with it was that it wasn't as developed as ODE, course we may have done something wrong.
