Framerate Optimization To address this, Unity offers several profiling and debugging tools. Another essential tool, the Shader Graph heatmap, provides a visual estimate of the cost associated with different Shader Graph nodes. Developers can leverage this feedback to make informed decisions when optimizing shader programs.

Recently, NetEase introduced Mesh Shader support to Justice. Soon we found we can combine Mesh Shaders with auto-generated LODs to achieve almost only-resolution-relevant rendering complexity, instead of polygon number. With so much potential of Mesh Shader, we conceive that it would be the main stream of future games.

Fortunately, NVIDIA has upgraded the NVIDIA Nsight debugging tool in time, making it an easier process for development work. Debugging costs us significant time. From beginning to end, it took us about five to six months.
