How to fix storage lag on GreatWall GW3300 in Frostpunk 2?
Once my colony hit 3,000 pops, the flood of construction commands absolutely hammered the GreatWall GW3300 512GB, causing these bizarre 0.5-second freezes. It's a classic SLC cache exhaustion issue; I saw sequential writes plummet from 420MB/s to a pathetic 85-110MB/s. I wasted time disabling Fast Startup in Windows, which did absolutely nothing for the NVMe protocol—totally frustrating. I eventually dove into the driver advanced settings and forced the I/O queue depth from 32 up to 64, while locking the page file to a static 16GB range. Monitoring with HWiNFO showed temps between 42-51℃, and latency dropped from a laggy 12-25ms to a crisp 4-7ms. I actually hit a BSOD right after the queue tweak due to a driver conflict, but a chipset update sorted it out. Now 4K random reads stay at 52-58MB/s. According to CrystalDiskMark, frame times are finally rock steady at 5.1-6.4ms.
