I'm getting sync lag and stutters in 128-player BF2042 matches on my Ryzen 7 9800X3D, should I change core affinity?

In the middle of a chaotic battlefield with explosions everywhere, the game would just hitch for a millisecond, which really kills the immersion of a high-end CPU. Using a latency tester, I found that the 3D V-Cache was hitting 12-18ms sync jumps during heavy physics calculations, causing the L3 cache hit rate to dive below 70%. I tried lowering the physics settings in-game first; the FPS went up, but the I/O latency was still there, proving that this was a low-level scheduling problem. I installed the latest AMD chipset drivers and used Process Lasso to force the game process onto the 3D cache cores. In subsequent monitoring, memory access latency dropped from 75ns to a stable 62-66ns, and the game felt way more fluid. I did have a moment where my browser crashed after binding the cores, but moving non-game processes to other logical cores solved it. CPU temps stayed between 60-72℃. After several stress loops, the latency is confirmed stable at 62-66ns.
