Hunting down performance bottlenecks with quantitative data?
When your curves look like a heart attack, average FPS is a useless number. On Windows 11 24H2, I used 3DMark's detailed log export to crunch the numbers. With the CPU staying between 71℃ - 79℃, I realized the real culprit was actually instant peaks in memory latency. I spent some time in the BIOS micro-tuning the memory timings, which recovered 16ms - 30ms of latency and finally smoothed out those messy curves. A pro tip: you have to kill every single background app during this analysis, or the noise ruins the data. After three cycles, I locked in a stable frame rate of 56fps - 61fps. It didn't magically fix every single dip, but it proved I didn't need to waste money on a hardware upgrade. Seeing the hard data made the whole grinding process actually worth it.
