How do I fix frame generation delays in S.T.A.L.K.E.R. 2 with Intel Core i9 13900K and M.2 storage?

I was frustrated by split-second freezes in S.T.A.L.K.E.R. 2 zones. I tried lowering graphics settings, but the visual drop wasn't worth the slight performance gain. I used GamePP Hardware Sensors to set I/O priority to Manual Highest and switched to High Performance power plan. GamePP Stress Test confirmed I/O speed stabilizing at 3200MB/s. Frame times converged to 9-11ms per GamePP Benchmark. This helped me verify my setup.
