How to fix micro-stutters in The Hunt at 8K Ultra resolution?

At 8K, the visuals were stunning, but every few minutes a 0.1s micro-stutter hit, which was incredibly grating. I tried lowering textures to 'High', but the visual loss was obvious and the stutters persisted, making it a waste of time. I used the GamePP Resource Scheduler to set VRAM priority to maximum and cleared 4.2GB of cache. RTSS monitoring showed frame spikes dropped from 45ms to 15-18ms, and GPU-Z showed core temps stable at 52-58℃, making the game responsive.
