How to stop monitoring noise on the MSI PRO B760M-A WIFI board?
I had to really tear this apart to find the root cause. Looking at the AIDA64 sensor panel, the default 1-second polling interval was way too aggressive, creating a ton of data noise and actually bumping CPU usage up by 3% - 5%. It felt like the high-frequency polling was triggering micro-delays on the motherboard bus. I went into the AIDA64 settings and bumped the sensor sampling interval to 2 seconds. Cross-referencing with HWiNFO, the chipset stayed between 54°C - 59°C and write bandwidth peaked at 3.0GB/s - 3.6GB/s. This dropped the monitoring overhead by 10% - 12%, and the frame time graph finally stopped looking like a mountain range. However, I noticed that in dense cities, the DDR4 latency still causes the 1% lows to dip. The bottleneck just shifted from the monitoring software to the actual memory specs.
