Fix Onimusha 2 Shader Issues on Huntkey T620
Night battles in Onimusha 2 were ruined by color overflow and screen tearing. GPU-Z showed temps at 52-58°C, so it wasn't heat. I tried lowering ray tracing to High, but the visual quality became unacceptable. I realized it was a shader backlog. I used DDU to clean uninstall the driver, installed NVIDIA Studio Driver 560.94, and used GamePP Shader Compilation Queue Manager to clear 5.5GB of cache. RTSS confirmed frame generation time converged to 10-13ms. The path tracing looked crisp, and the immersion was fully restored without any artifacts.
