How do I handle bus latency and framedrops with a Samsung 9100 PRO 8TB in The Last of Us Part II?

Walking through the ruined city, the game would just hang for about 150ms, which is a total dealbreaker during fast combat. The PCIe 5.0 bus on the Samsung 9100 PRO 8TB was struggling with electromagnetic interference during high-bandwidth streams, causing data packet re-transmissions that pushed read latency between 110-135ns. I tried enabling 'Low Latency Mode' in the driver, but while the initial response was faster, the hitches actually happened more often, which was pretty stressful. I went into the BIOS, forced the M.2 slot to Gen5 mode, and set the PCIe link speed to maximum performance. Using a latency tester, random read latency dropped from 120ns to 88-95ns, and the scene transitions felt way smoother. The drive almost hit 82℃ when I first cranked the speed, so I had to swap in a heatsink with an active fan to keep it stable. Temps are now steady at 55-62℃. The frametime distribution graph confirms the response time is finally where it needs to be.
