Why does the Intel Core i9 13900K cause frame generation delays and noticeable lag during exploration in S.T.A.L.K.E.R. 2: Heart of Chornobyl?

While exploring the zones, the game froze for a split second, and frame times spiked significantly. I tried lowering graphics settings, but the visual quality drop was unacceptable. I used GamePP Hardware Sensors to set I/O priority to Manual Highest and switched the power plan to High Performance. GamePP Stress Test confirmed interface efficiency improvements, with I/O speed stabilizing at 3200MB/s and frame generation times converging to 9-11ms.
