Released in 2023 with version 9.23.1019, NVIDIA PhysX 9.23.1019 is the final legacy PhysX system software from NVIDIA, providing CPU-based physics acceleration for older games and applications that rely on the classic PhysX runtime, ensuring compatibility and performance on modern Windows systems.
Key Highlights
- Legacy Game Compatibility – Essential for running older PhysX-accelerated titles (pre-2015) with cloth, fluid, particle, and destruction effects on systems without dedicated PhysX hardware.
- CPU Physics Processing – Software-based physics simulation supporting multi-threaded CPU execution for smooth performance even on modern multi-core processors.
- Classic PhysX Effects – Enables advanced physics features like rigid body dynamics, ragdoll, vehicle simulation, and deformable objects in supported games.
- APEX Integration – Includes support for NVIDIA APEX modules for enhanced destruction, clothing, and turbulence effects in compatible titles.
- System-Wide Installation – Global runtime installation allowing any PhysX-enabled application to utilize the physics engine without bundled copies.
- Lightweight & Stable – Minimal resource usage with no background services, proven stability on Windows 11, and no conflicts with modern GPU drivers.
- Performance & Stability – Final optimized build with bug fixes, improved multi-threading, and compatibility for legacy applications on current Windows versions.
System Requirements
- Windows 11 64-bit (or Windows 10 / 8 / 7)
- 4 GB RAM minimum (8 GB+ recommended)
- Integrated GPU sufficient
