Well, the core issue is still drawing. I took another look at some profiles again and seems like its not the renderer limiting this to 27k! I still had some stupid scene-graph traversal... But clustering and culling is 53us and 33us respectively, but the draw is 7ms. So a frame (on the GPU-side) is like 7ms, and some 100-200 us on the CPU side.

Should really dive deeper and update the measurements for final results...

This seems fairly well optimized. There's probably room to squeeze out some more perf, but not dramatic improvements. Maybe preventing overdraw of shaded pixels by doing a depth prepass would help.

Without digging into the detailed breakdown, I would assume that the sheer amount of teeny tiny triangles is the main bottleneck in this benchmark scene. When triangles become smaller than about 4x4 pixels, GPU utilization for raterization starts to diminish. And with the scaled down dragons, there's a lot of then in the frame.

Worth noting that the GTX 1070 is nearly 10 year old "mainstream" GPU. I'd imagine a 5090 or something could push the numbers fair bit more higher.

Fun to see you ;) Love your site!
