Why is Dead Space 2 flickering during lighting scenes on my Zotac GPU?

The constant screen flickering during lighting transitions in Dead Space 2 broke my immersion completely. I tried lowering graphics quality, but the stutter persisted, making the game unplayable. I identified shader compilation queue errors as the culprit. I used the GamePP Shader Compilation Queue Manager to manually clear the cache and optimized the power plan. After these changes, AIDA64 reports a locked 120 FPS, and HWiNFO shows steady GPU usage at 85%, finally setting the stage for a smooth experience.
