[upstream] Optimizations (erincatto/box2d#1050) - #93
Merged
Conversation
Improved performance, up to 20% gain in stacking scenarios. Behavior change: contact solver bias stage no longer applies friction (almost free perf gain) Behavior change: b2World_Step still performs all operations, including collision when timeStep == 0. b2WorldDef now has b2Capacity that lets you pre-size some arrays to reduce allocations. Optimized hit events. These are basically free now. Cleaned up and optimized solver scheduling. Converted to new dynamic array type. Added threading logic to prevent theoretical solver deadlock if the user task system stalls worker 0. Added Compounds benchmark.

Thanks! This update is big. When you have a spare minute, unleash a new NuGet package for us mortals 🤣🙈. |
