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.

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.

Godot 3.5: Can't stop won't stop

Mircosoft Game Dev

The new NavigationServer adds support for obstacle avoidance using the RVO2 library, and navigation meshes can now be baked at runtime. For more advanced use cases, you can use TextMesh to generate 3D meshes from font glyphs, so you can add WordArt to your scenes ;). Asynchronous shader compilation + caching (ubershader).
