If you decompile a PC game from 2011-2013, you will likely find strings pointing to "Havok 2010.2.0-r1". Why?
If you ever find a dusty .pdb file or an old hkpHingeConstraint in a disassembled executable, tip your hat to version 2.0-r1. It carried the weight of an entire generation of gaming.

While Havok had CCD for years, version 2.0-r1 introduced a new "Speculative CCD" for fast-moving bullets. Traditional swept-tests were expensive; the new speculative system allowed for ray-cast proxies that ran every 5 frames without triggering full manifold generation.
While deterministic on the same hardware (same CPU, same thread count), across PS3 vs. 360 vs. PC, physics simulations diverged after ~500 frames. This broke networked physics without custom rollback. If you decompile a PC game from 2011-2013,
Before we dive into features, let’s decode the nomenclature. Unlike modern semantic versioning (SemVer), Havok 2010 used a date-based system combined with an internal API version.

While specific version numbers are rarely publicized by studios, the 2010-era SDK was the foundational technology for some of the most influential titles of the early 2010s, including:
