Should I use DLSS settings to fix underwater latency spikes?

GamePP DLSS Calibrator was the key to fixing underwater lag. VRAM bandwidth was saturated at 95%, causing 32ms latency. I reduced render resolution from 100% to 85% and switched to Balanced mode. Frame time stabilized at 12-15ms via RTSS, and frame rate jumped to 78 FPS, eliminating the stutter entirely.
