How to resolve PCIe bandwidth drops on MSI PRO B760M-A WIFI?
The texture flickering was absolutely hideous, especially in the dark forest sections where the lighting would just snap, making my eyes ache. Looking at the logs, the PCIe slot on my MSI PRO B760M-A WIFI DDR4 II was hitting these random bandwidth dips of 3.2-5.1GB/s under load. My first instinct was to lower the global graphics settings, but that just made the image look grainy and cheap—not an option for me. I decided to go old-school: used electronic contact cleaner on the gold fingers, reseated the GPU, and forced the PCIe version to Gen 4.0 in the BIOS. Running GPU-Z, the bus interface stayed locked at x16 4.0 without any more dips. I did hit a snag where the system wouldn't recognize my SSD twice after the lock, but disabling the storage controller's power management fixed it. VRM temps sat comfortably between 55-62℃. Once the transport protocol was stabilized, the flickering vanished completely. It was a tedious struggle with an evasive bug, but the hardware compatibility is finally sorted.
