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.

Unlocking GPU Intrinsics in HLSL

Nvidia

For example, a shader can use warp shuffle instructions to exchange data between threads in a warp without going through shared memory, which is especially valuable in pixel shaders where there is no shared memory. Or a shader can perform atomic additions on half-precision floating-point numbers in global memory. x, u1 mov r3.yz,

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.

and included in this beta are: Asynchronous shader compilation + caching (ubershader) ( GH-53411 ). A long awaited solution to shader compilation stuttering on OpenGL, courtesy Pedro J. Anything behind the polygon will be culled from view. Shaders: Many improvements backported from master ( GH-56794 ).

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.
