In fact, hardware transitions frequently served to thin the herd, with the cost increase being the final blow that saw many struggling publishers and developers shut their doors; the first couple of years of a new console generation could be generally expected to see such a cull. Read more.

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.

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. Moving forward, and with my full focus on Godot development, my goal is to work on Godot's 3D rendering and help bring Godot 4.0

using data oriented algorithms to process the culling of objects and both secondary command buffers and automatic batching to efficiently submit the draw primitives. The compatibility backend is based on OpenGL ES 3.0 / OpenGL 3.3 / WebGL 2.0 and is intended to run on very old PC hardware as well as most older (still working) mobile phones.

Up till now a significant missing feature in the renderer has been the ability to cull (prevent rendering) objects that are within the camera view, but occluded by another object (for instance a wall).

Learning how to use occlusion culling will also help you in this case. In my projects at most, I use 4 cameras if I need to, but I try to make it less than that. When you need to break the rule here, always use the profiler to test things and see if the frame rate has changed.

I have also set up Culling Mask so that the camera captures only the things with the correct layer. It’s good to change Clear Flags to Solid Color and select black, so that everything not rendered by our camera remains in this particular color, and then set opacity for black to 0. This is not obligatory though, you can also render everything.

Finally we update the culling mask and remove the default layer by clicking on it. The camera will need some adjustment to work as a minimap camera but the first thing we will do is rename it to MapCam. Then we will set its projection method to Orthographic, its size to 7 and its default color to black.

We are lucky that despite the culling of thousands of 5-star reviews, only a handful of people rated the game 3-stars or lower and so our average is still a respectable 4.92 Instead, 13 days after our release, we have 25 fewer reviews (622) than what we had on the first day. but even so, the question of Why? burns in our minds.

The first is that it uses a very large library of mine, most of which is not used in this engine, so I'd have to go though and cull out all the cruft, not to mention all the proprietary console crap. Releasing the engine source (c++) is problematic for a few reasons. I also use some third party source I don't have the rights to release.
