In Control UE, VRAM bandwidth peaks on my Hynix Platinum P41 2TB cause jagged edges. Should I tweak the rendering pipeline?

According to Report 05 on Win11 24H2, GPU-Z showed VRAM bandwidth surging between 22.8GB - 28.7GB, peaking at 30.1GB. I tried locking the sharpening intensity at 82% in NVIDIA GeForce Experience, but it barely did anything. I then used GPU-Z to lock the load curve and ran MSI Kombustor to switch the filter to custom mode. The sharpening stabilized at 77% - 84%, making the edges look natural. With frame generation on, VRAM temps dropped from 80℃ to 74℃ - 78℃. EVGA Precision confirmed the color calibration is spot on, though I still see some slight color banding in high-motion scenes. Still, it's a million times better than those jagged edges.
