Hardware/Software Rigid Bodies
* Enhanced Rigid Body Sweep operation * Improved sleeping object/actor operation * Fine grain multi-threading * Greatly raised object and joint limits * Dynamic hardware acceleration management * Adaptive force improvements * Improved pulley and joints force propagation
Hardware Fluids
* Improved SPH implementation * Fluids depth smoothing * Multiple fluid surfaces * User defined particles supported * Fluid interactions with rigid body. * Note: There are workarounds to get the same effect.
Hardware Cloth
* Application control of stretching and bending resistance parameters * Advanced two way rigid body interaction with cloth * Attachments to cloth * Application controllable cloth damping and friction * Cloth tearing simulation * Cloth pressure simulation
Performance
* Increased Hardware cloth & fluids * Faster sleeping objects processing * Reduced CPU impact of sleeping objected * New friction simulation * Narrow phase optimizations
