Dealing with resource scheduling delays on MSI A520M-A PRO?
Walking through a crowded city only to have the entire world freeze for a second is an absolutely miserable experience. On this MSI A520M-A PRO, the PCIe lanes were hitting scheduling delays of 110-140ms during high-throughput data bursts, which crippled the VRAM exchange efficiency. I started by clearing temporary cache files, but that only shaved off about 0.5 seconds from the load time, which felt like a total waste of time and left me feeling pretty defeated. I then went into the BIOS and forced the PCIe link speed to Gen3 instead of leaving it on Auto, and flashed the latest chipset drivers. In my frame time logs, the erratic 18-42ms spikes quickly settled into a tight 12-16ms range, making scene transitions feel way more fluid. Interestingly, when I first switched to Gen3, some of my NVMe drives wouldn't even show up in the BIOS until I disabled the interface power management settings. Currently, the board core temp sits at 55-61℃ with fans spinning at 1200-1400 RPM. System logs confirm the I/O blocking is gone, and memory temps are holding steady at 55-61℃.
