A recent breakthrough in GPU physics architecture has sparked excitement among developers. This innovative C++ simulation is handling 100 million active particles in real-time, demonstrating unprecedented capabilities on the RTX 5090.
Insights into the Stress Test
The stress test served as the first successful validation of a custom-built GPU physics framework designed specifically for advanced simulations. Users can only see about 50,000 points in the viewport due to rendering limitations, but the backend efficiently runs calculations for each of the 100 million particles. This isn't your typical game physics; it’s a sophisticated scientific model.
Key components of the simulation include:
Relativistic Physics: Calculating forces affecting particles' behavior under extreme velocities, including the Lorentz force.
Matter Interactions: Utilizing the Bethe-Bloch formula for energy loss and simulating scattering within materials.
The performance stats are striking:
Stable Throughput: 15 FPS, equating to 1.5 billion particle updates per second.
Community Reactions
Comments from the user boards reflect an enthusiastic response:
"This is pretty cool. Have you tested to see how many particles it can do while getting >60 FPS?"
There’s curiosity about future potential applications. One user highlighted how the original architecture wasn’t even aimed at gaming, stating:
"This project didn't start in the game domain at all. I originally developed the GPU solver for my AI work."
Exploring Future Applications
The developer sees a wide range of applications beyond gaming, including:
Large-N particle simulation beyond traditional limits.
Real-time interactions in gaming environments, such as field effects and granular materials.
Enhanced destruction systems that accurately reflect physics.
Another intriguing comment mentioned prior success with 30 million particles running with 40+ FPS, showing promise for scalability.
