In reply to JeGX. It can't be (just/only) geometry instancing because the quote in the article here also says: "which would be impossible to achieve by using CPU-based draw call submission." Geometry instancing still has CPU-based draw call submission. The GravityMark GPU Benchmark programmers seem to claim not to use such CPU-based methods.

In reply to JeGX. Could the test be using compute shaders?

In reply to sf sdf. geometry instancing maybe...

Is this test using mesh shaders? Looking at the high utilization (99%) and following explanation:

Even relatively older GPUs like Nvidia’s GTX 1060 and mobile GPUs show excellent performance, which would be impossible to achieve by using CPU-based draw call submission. We avoid typical CPU-based performance bottlenecks by delegating the entirety of scene management and rendering steps exclusively to the GPU.
