How do I fix simulation stutter in Need for Speed caused by the AMD Ryzen 5 7500F's single-core bottleneck?

Simulating large scenes in Need for Speed was painful; the AMD Ryzen 5 7500F's single-core performance was bottlenecked, causing stutter. I tried adding memory, but the effect was poor, and the stutter remained. I used GamePP Resource Scheduler to adjust thread priority and optimized the power plan. This ensured the game process got the CPU cycles it needed. GamePP Benchmark Test confirmed the improvement, showing a 20% increase in simulation speed. The CPU temperature stayed normal, and the simulation runs smoothly now.
