Using Corsair Vengeance RAM in The Sims 5 with an AI sharpening filter, but character edges have white jagged artifacts. How to fix?

Captured in Visual Test 20250810-S5 (Win11 + GamePP Plugin). At 80% sharpening, 4K screenshots at 200% zoom revealed blatant over-enhancement of edge pixels. I manually slid the GamePP intensity down to a range of 40% - 50% while enabling accompanying Anti-Aliasing. The skin textures returned to a natural state, and those eye-straining white halos vanished, making long sessions actually bearable. Monitoring showed an 0.8GB increase in VRAM draw and a negligible 3-5 FPS drop. However, interior scenes with flickering lights still produce sporadic shimmering, an AI algorithmic limit that no amount of manual tuning can currently resolve.
