How to reduce input lag and screen tearing in Human Host?

While building my base, the screen would tear visibly during fast turns, and input response lagged by about 30ms—it was an extremely uncomfortable feeling. I first tried disabling V-Sync and enabling full-screen optimizations, but the tearing persisted and frame fluctuations increased. I used the GamePP DLSS/FSR Image Sampling Calibrator to switch sampling to manual, set sharpening to 65, and forced Low Latency mode. Frame generation time converged to 8-14ms per RTSS, and GPU temperature stayed at 60-66℃ per GPU-Z.
