VRR flicker is usually a stability problem, not a broken display. Learn why it happens (range edges, luminance changes) and the fix order that actually works.
Shader stutter happens when new effects compile in real time. Learn how to identify it fast and the practical ways to reduce hitches without placebo tweaks.
Reflex reduces render queue delay when the game is GPU-bound and stable. Learn the practical conditions where it helps and the traps that make it pointless.
Higher refresh can expose instability. Use this checklist to diagnose why 120Hz feels worse: wrong mode, wrong refresh path, VRR range issues, or missing caps.
Many HDR problems are tone mapping problems. ‘Dynamic’ modes can crush highlights or lift blacks into gray fog. Use this baseline to keep detail readable.
