Is the Colorful B450M-T M.2 bottlenecking Silent Hill 2?
Walking through those foggy streets was a mess; the edges of the screen had this distracting tearing that made me seriously anxious. It turns out the PCIe 3.0 lanes on the Colorful B450M-T M.2 were acting up—with a fast NVMe drive installed, the GPU was getting throttled to x8 mode, adding a 10-20ms lag to data transfers. I wasted time messing with V-Sync and various driver options, but that just pushed my input lag over 30ms, which was a total disaster. I finally flashed the latest BIOS and went into Advanced settings to force the PCIe link speed to Gen3 and put the M.2 slot in low-power mode. GPU-Z confirmed the bandwidth jumped from 7.5GB/s back to 15.8GB/s, and the tearing vanished. I did mess up the boot order during the BIOS update, so I had to spend a few minutes fixing the boot priority. Board temps are sitting at 42-50℃. Frame time analysis shows the bandwidth spikes are gone, and the controls finally feel snappy.
