I'm getting massive data bottlenecks and stuttering while riding fast in Days Gone, why does this keep happening?

While tearing through the forest, my storage read latency suddenly spiked to 120-150ms, causing these annoying periodic micro-stutters that honestly reminded me of the old HDD days. At first, I thought the SSD was overheating, so I slapped on an M.2 heatsink. The temp dropped by 5℃, but the stuttering didn't budge, which was incredibly frustrating. I eventually dove into the BIOS Advanced settings and forced the PCIe link speed to Gen 3 instead of Auto, while also tweaking the memory channel prefetch parameters. Checking HWiNFO, I saw the I/O throughput climb from 2.1-2.8GB/s to a steady 3.2-3.5GB/s, and the frame time variance tightened from 14.5-22.1ms down to 9.8-11.2ms. I actually messed up at first by enabling Fast Boot, which broke my system boot sequence; I had to reset the CMOS and re-optimize the bus weights before things actually smoothed out. Even though the VRM area still hits 55-60℃ under heavy load, the responsiveness is night and day. A final check with CrystalDiskMark confirmed the link bandwidth is peaking, with frame times rock steady at 9.8-11.2ms.
