Volt (VPhysics Jolt) is a drop-in replacement physics module for Valve's Source Engine, replacing the legacy IVP/Havok-based VPhysics with Jolt Physics. It is designed for high performance, simulating thousands of physics objects simultaneously without degrading tick rate or framerate.

Use cases

• replace the slow legacy VPhysics in Source Engine games with a fast modern physics engine
• simulate thousands of physics props in Garry's Mod without framerate collapse
• get ragdolls, constraints, triggers, and vehicles working through Jolt Physics in Source
• add Portal support and save/restore compatibility to a Jolt-based Source physics backend
• avoid physics solver crashes in Source Engine mods
• run a modern physics engine in Source Engine mods

When to choose

• you run a Source Engine server or mod that needs high-performance physics with many active objects
• you want a mostly feature-complete VPhysics replacement built on Jolt Physics
• you need crash-resistant physics simulation in Source Engine games

When to avoid

• you rely on raycast vehicles like the airboat, which are not yet supported
• you need breakable constraints, which are still missing
• you are not working with the Source Engine or its derivatives
