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.

My first task will be integrating an occlusion culling system into the new Vulkan renderer. While occlusion culling is not a silver bullet, it can give big performance improvements in a variety of scenes. Debug output of the prototype implementation.

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.

Dev snapshot: Godot 4.0 beta 3

Mircosoft Game Dev

Our SCons setup used to have tools and target options that were combined to build either the editor or the export templates, and define whether it’s a “release” or “debug” build. The “debug” term in that setup was quite ambiguous however and the source of a lot of confusion, as described in godot-proposals#3371.

Best Practices for Using NVIDIA RTX Ray Tracing (Updated)

Nvidia

It can be directly in the AS build calls or in some related task like the culling of the objects. Cull instances for TLAS. Instead, cull instances depending on the situation. For example, consider culling based on an expanded camera frustum. Use face culling only when required for correctness.
