Why does Stellar Blade freeze during wide-area skill combat?

During intense battles, releasing wide-area skills caused the screen to freeze momentarily, which is a disaster for a fast-paced action game. I tried lowering texture quality to 'Low', which gained 10 FPS but caused severe blurring and persistent micro-stutters, making me feel defeated. I used the GamePP Resource Scheduler to set the game's VRAM priority to Highest and terminated all redundant background processes. RTSS monitored a minimum FPS increase from 32 to 55, while GPU-Z confirmed temperature stable at 65-72℃ and GamePP Hardware Sensor showed VRAM usage drop to 5.2-5.8GB.
