Are erratic sawtooth curves ruining your bottleneck analysis?

Under extreme loads, single 3DMark runs are plagued by background noise, leading to 15% to 20% abnormal fluctuations in the curve. To kill the noise, I built a sample group of 10 loop tests on Win11 24H2 with every unnecessary service killed. The data showed CPU temps stubbornly sticking between 74℃ and 83℃, while the framerate bounced between 59 FPS and 64 FPS. The quantitative result pinpointed the bottleneck as instant memory latency spikes, not the motherboard VRMs. Once I compressed the analysis delay from 33ms to 15ms, the issue was locked to the memory controller. Still, in ultra-preset forest scenes, frames dive to 50 FPS, which is clearly an engine optimization flaw, not hardware.
