From PhysX Wiki
MassFX is an unified physics simulation framework, introduced by Autodesk in 3ds Max 2012 (and 3ds Max Design). While being based on PhysX SDK, MassFX has replaced old Havok Reactor physics engine. Unlike Reactor, MassFX is performing simulation directly in viewports.

MassFX is comprised of several simulation modules - first one, mRigids rigid body dynamics, was released as part of 3ds Max 2012, second - mCloth cloth simulation was presented in 3ds Max 2013. More advanced modules are in development.
Mass FX Modules
mRigids is a module, responcible for simulation of rigid bodies. It supports static, kinematic and dynamic rigid bodies (box, sphere, capsule, convex and composite concave physical mesh types), various constraints (rigid, twist, slide, hinge, universal and ball & socket), dynamic and kinematic ragdolls. Results of the simulation can be baked in keyframes for subsequent rendering.
Rigid body objects can be influenced by standart 3ds Max Forces, like Vortex, PBomb or Wind (MassFX 2013 feature).
mRigids module is using PhysX SDK 2.8.4. and does not support hardware acceleration.
mCloth is a module capable of cloth simulation. It provides full collisions with mRigids bodies with 2-way interaction, supports per-vertex tearing, internal pressure, vertex group operations (like pin or attach to object) with support for keyframe animation, kinematic cloth, baking to keyframes.
Cloth objects can be influenced by standart 3ds Max Forces, like Vortex, PBomb or Wind (MassFX 2013 feature).
mCloth module is using PhysX SDK 2.8.4.
3ds Max 2014 includes new MassFX module - mParticles, which is, basically, a modified version of Orbaz Particle Flow Box #2 plug-in.
mParticles is an all-purpose simulation solution, that can be used to calculate behavior of various types of objects: particles, deformables (glued particles), cloth, fluids and smoke.
Module is using PhysX SDK 2.8.x
- You can install PhysX plug-in for 3ds Max over MassFX - plug-in will substitute MassFX and restore it back after uninstall.
- According to Autodesk XBR webinar, future releases of MassFX will include cloth and sofbodies simulation, particles, ropes and forces.
