How do I fix Mass Effect shader stutter and visual tearing on Onda H610M+ with Path Tracing?

In Night City, Path Tracing caused color bleeding and 22-35ms frame times. I tried lowering ray tracing to High, but the visual loss was unacceptable. I used DDU for a clean NVIDIA Studio install and the GamePP Shader Compilation Queue Manager to clear 6.8GB of cache. Per RTSS, frame times dropped to 13-16ms, and GPU-Z showed VRAM stable at 12.4-14.1GB. The artifacts are gone.
