Why does Delta Force lag during large battlefield firefights?

I felt totally cheated when smoke and explosions caused distracting micro-stutters, making my aiming feel sluggish. I first tried forcing High Performance mode in the drivers, but while FPS rose slightly, the frequency of frame drops actually increased, leaving me confused. I then used the GamePP Resource Scheduler to elevate the game process priority from Normal to Real-time. RTSS monitoring showed frame time converged from 12-48ms to a stable 8-11ms, with GPU-Z recording 2450-2520MHz and HWMonitor showing 64-69℃. It's a total game-changer for stability at 11ms.
