Why does Overwatch 2 stutter during team fights, and should I check timing or adjust sampling on Asgard RAM?

I noticed the frame rate dropping significantly every time a 5v5 team fight started in Overwatch 2. I tried enabling XMP in the BIOS to boost my Asgard Hel DDR5 5600, but that prevented the system from booting entirely. I had to revert and find a software solution. I used GamePP DLSS/FSR Image Sampling Calibrator to set the render resolution to 95% and adjust the sharpening intensity. AIDA64 monitoring showed the read/write latency stabilizing from 12.5-14.8ns to 10.2-11.5ns, and the frame rate locked at a smooth 144 FPS. The combat feels fluid and responsive now.
