Is the ASUS ROG STRIX X870-A Snow causing bottlenecks in Judgment?
Walking through the neon streets of Tokyo with this setup is usually a dream, but I noticed something weird: whenever I turned quickly, the FPS would dip from 140 to 70. On a high-refresh monitor, that stutter is glaring. My ASUS X870-A Snow was defaulting the PCIe slot to Gen 4, capping the GPU bandwidth at 31.5GB/s. I tried the 'High Performance' driver setting, but the lag persisted, making me realize the issue was at the hardware link level. I dove into the BIOS, forced the PCIe link speed to Gen 5, and switched Windows to the 'Ultimate Performance' power plan. A GPU-Z bus interface test showed bandwidth jumping to 63GB/s, and the stutters vanished. Interestingly, the first time I toggled Gen 5, I got a brief black screen during boot; I had to update the GPU VBIOS to fully stabilize it. Board temps stay between 48℃ and 55℃. Frame times are now a rock-solid 4.2-5.8ms.
