Why is Mass Effect stuttering on my GALAX B760M Light D4?

While loading new areas, my CPU usage on the GALAX B760M Light D4 hit 90%, causing severe stutter. I tried clearing background processes, but system services kept interfering. The game remained unplayable. I used the GamePP Resource Scheduler Panel to elevate the game process priority to Real-time. This ensured the game got the CPU resources it needed. CPU usage dropped to 75% per HWiNFO. Frame rate stabilized at 90 FPS via RTSS. Core temperature stayed at 72-76℃. The stutter is gone, and I verified the scheduling state is stable.
