Use Compressed Textures : Textured images can be saved with lower resolutions while compressed formats such as ASTC and DXT1 and DXT5 reduce memory usage without quality reduction. Texture Atlasing combines multiple textures into one atlas to lower the number of texture switches that occur.

And even before an era of SRPs (Scriptable Render Pipelines), there was a good amount of solid features like today’s topic: Render textures. In this post I’m going to explain to you how to use render textures in your game. For shaders, I used Amplify Shader Editor to add some visual effects on top of the render texture.

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.

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.

At the end of the day, the use case where Vulkan and DirectX12 make the most sense is when you have hundreds of thousands of objects, which are all different (different geometry, textures, etc.), Detect when shaders read from screen texture and automatically copy screen to back-buffer on demand. On a texture, a dual paraboloid is used.
