Why does Nioh 2 hitch on the AMD Ryzen 9 9950X3D?
Every time I went for a high-speed parry, the screen would just freeze for a split second, and that unpredictability was driving me insane. With the 9950X3D's dual CCD layout, if threads jump between the cache-heavy and non-cache cores, you get this nasty 110ns - 140ns latency penalty. I tried underclocking to find some stability, but that was a total fail—the FPS stayed the same but input lag increased by 5ms, which was just frustrating. I finally installed the latest AMD chipset drivers and used a tool to force the game process onto the CCD0 cores (the ones with the 3D V-Cache). My latency analyzer showed memory access drops from a chaotic state to a clean 62ns - 71ns, and the hitches vanished. Funnily enough, my browser started lagging after the bind, so I had to shove all background apps onto CCD1 to balance it out. CPU temps are sitting pretty at 62℃ - 70℃. The in-game performance overlay confirms the scheduling is working, and the controls finally feel snappy.
