Why does Far Cry 7 freeze for 0.4s during jungle exploration on H610E-B?

Sprinting through the jungle, the screen would suddenly freeze for 0.4 seconds, which felt agonizing during fast-paced action. I tried switching DLSS to Performance mode; the FPS increased, but the image became blurry and smeared, which I couldn't accept. I used the GamePP Image Sampling Calibrator to raise sharpening from 0.3 to 0.62 to remove white edges. The frame rate stabilized at 42-48 FPS per RTSS, and motherboard temperature stayed at 48-55℃ per HWiNFO64, making the movement feel incredibly smooth.
