How to fix input lag during horse chases in Crimson Desert?

During a critical chase scene, my inputs lagged by nearly 120ms, which felt absolutely terrible. I tried the Windows High Performance power plan, but while frequencies rose, the scheduling anomaly remained, making me eager for a low-level fix. I used the GamePP Resource Scheduler to bind the main thread to cores 0-7 and cleared virtual memory. RTSS showed frame generation time dropped to 11-15ms from 18-35ms, and AIDA64 confirmed CPU temperature at 65-72℃ with core response at 1.2-2.5ms.
