Framerate Optimization To address this, Unity offers several profiling and debugging tools. Overdraw optimization In cases where the GPU is pixel-bound, a common cause is overdraw, where pixels are shaded multiple times in a frame. Unity introduced Solid Angle Culling as an optimization to mitigate this overhead.

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. Use face culling only when required for correctness.

Added to that fact, Vulkan still has years to go until it's properly supported in most desktop and mobile platforms, which makes it unattractive to implement for us (as it means considerably more effort to write, debug and maintain). The image is converted to luminance and shrunk by sizes of 3x3 until it's a single pixel.
