How to fix Samsung 9100 PRO read/write throughput in Frostpunk 2?
When my industrial zones started scaling up, the read/write curves on my Samsung 9100 PRO went completely haywire with weird sawtooth fluctuations, especially after hitting city level 3. I noticed the PCIe 5.0 bus was struggling with fragmented resources, with instant latency spiking between 112ms - 135ms, which felt like a total slideshow. I tried disabling Fast Startup in Windows first, but that was a waste of time since it just added 4 seconds to my boot time. I eventually dove into the Samsung Magician software and manually locked the driver queue depth to 32 while switching my power plan to Ultimate Performance. Checking HWiNFO, the read latency finally settled down to 42ms - 55ms, and the asset streaming became way more fluid. I did hit two minor system freezes right after the change, but forcing the motherboard PCIe mode to Gen5 instead of Auto fixed it for good. Temps stayed rock steady between 52℃ - 61℃. According to the system performance analyzer, the scheduling is finally stable with frame times sitting at 5.1ms - 6.4ms.
