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.

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. Moving the CPU work to one or more worker threads is potentially beneficial.

Practical Use of Render Textures

The Knights of Unity

For shaders, I used Amplify Shader Editor to add some visual effects on top of the render texture. I have also set up Culling Mask so that the camera captures only the things with the correct layer. Then I’ve put the recorded render texture to a Standard Shader. Then the texture is plugged into the created shader.

New improvements for GPUParticles in Godot 4.0

Mircosoft Game Dev

GPUParticles : Processes particles on GPU, allows very large amount of particles at little cost, and with ability to write custom particle shaders. x and the shader used is almost identical (should be easy to port). It can also be done from within a particle shader itself by chaining another particle system as a sub-emitter.
