On December 5, news emerged that back in February of this year, NVIDIA's RTX 50 series graphics cards ceased their support for 32-bit CUDA applications. This move effectively marked the end of the road for the 32-bit-exclusive PhysX physics acceleration technology. PhysX, which made its debut in 2004, was once a dominant force in the gaming industry as a physics simulation engine. It allowed for the realistic depiction of physical effects by harnessing the power of GPU acceleration. However, with the advent of the RTX 50 series, the 32-bit iteration of PhysX officially bowed out of the spotlight. Fast forward two months, and NVIDIA made a significant announcement: the GPU core source code for PhysX was being made open-source. This move granted developers unrestricted access to the entire codebase, empowering them to tweak and modify it as they saw fit. This open-source strategy doesn't just cater to the latest RTX 50 series graphics cards. Through the BSD-3 license agreement, developers are now free to innovate without being shackled to specific hardware setups. This development paves the way for even more sophisticated and immersive physics effects in the gaming world.
