Advanced GPU optimization techniques in Unity 6 • Insights from Unite 2024

PreMortem.Games

Framerate Optimization To address this, Unity offers several profiling and debugging tools. Unity’s Frustum Culling and Depth Rejection techniques help reduce the amount of geometry processed by discarding objects outside the camera’s view or hidden by others. In some cases, Solid Angle Culling reduced ARTAS processing time by 60%.

Godot 4.0 optimization progress report

Mircosoft Game Dev

Before getting into the GPU side, several optimizations have been done on the CPU side: Culling is now done in a brute-force way which is extremely cache efficient. Everything in the main frame is culled at the same time, objects, light cascades, SDFGI cascades, etc. These test do culling on 10k objects. GPU Optimization.

Realistic Lighting in Justice with Mesh Shading

Nvidia

It lacks the ability to process mesh in a coarser grain than triangle, like meshlet culling. The underlying idea of the algorithm is, in the first place, to do culling, then draw the effective parts of mesh. With MeshShaders, the culling algorithms we use can be of great flexibility.
