New pages should also be added to the toc.yml file :P
| If physics causes your game to hang for a while when simulating for the first time, it may be related to just-in-time compilation. If it becomes a problem, consider running a small simulation that hits all the relevant codepaths (a bunch of objects colliding with constraints applied) behind a loading screen. Using an ahead-of-time compilation toolchain would also work. | ||
| ### General | ||
| - **JIT Compilation Spikes**: Large spikes in physics step time after launch may be due to JIT compilation. Consider running a small simulation behind a loading screen to prime all relevant code paths. AOT compilation can also help. | ||
| - **Thread Oversubscription**: If recurring spikes occur (especially in the solver), the operating system may be oversubscribing threads. Too many threads vying for CPU time can stall physics. In such cases, reduce the number of threads used by the simulation or by other parts of the engine. |

Can users access that from their game ?

They now can set the Thread count => stride3d/stride#2571
| - **Use Simple Shapes**: Spheres and capsules are fastest, then boxes and triangles, followed by cylinders and convex hulls. | ||
| - **Keep Hulls Small**: If using convex hulls, minimize vertex count. Complexity directly affects collision cost. | ||
| - **Limit Concave and Mesh Shapes**: Use compounds of simpler shapes instead of concave meshes whenever possible. If absolutely necessary, keep the triangle count low and shapes uniform in size. | ||
| - **Reuse Shapes**: Avoid creating many duplicate, large shapes (like complex hulls or meshes). Reusing shapes reduces memory bandwidth and cache issues. |

That's not accessible to users, I think we share shapes only in specific circumstances, maybe something to add as a todo on the engine side ?

That WAS not accessible ! stride3d/stride#2570 (:

Let me know once I can merge this 🙂 |
|
@Nicogo1705 could be Eideren's comments resolved so this could be merged, even though it might need more follow up updates/content? It seems there is already very helpful content here so we don't need to wait. Thanks. |
|
Well, everything is done, except stride3d/stride#2570 |
|
Thanks, well, we can wait then. |
