This deep dive into improving shader performance uses Nsight Graphics to profile Diablo® II: Resurrected. Learn about how latency caused by LDC Divergence (a phenomenon where load constant addresses differ within the same warp) can be identified and resolved with help from Nsight Graphics, yielding significant throughput improvements.
