How to fix texture streaming lag on Fanxiang S790 4TB?
The distant forest textures looked like melting wax, which is absolutely lethal in an open-world game. Looking back at the data, once the Fanxiang S790 4TB hit over 1TB of writes, the dynamic SLC cache just gave up, and my read speeds plummeted from 7400MB/s down to a pathetic 1200MB/s - 1500MB/s range. I tried the basic route of clearing system temp files to free up space, but a 10GB gain did nothing for the underlying seek latency; that trial-and-error phase was honestly frustrating. I ended up using a partition tool to perform a full sector alignment and migrated the game directory to a contiguous storage area. In the Resource Monitor, disk active time dropped from a constant 95% saturation to a healthy 40% - 55%, and textures started popping in way faster. I actually hit a snag where a partition table conflict caused a hard reboot during the alignment, but a bad sector scan cleared it up. The SSD hovered between 45℃ - 52℃, and the stress was visibly lower. Comparative tests showed a 15% bump in random reads, and the storage glitch is finally gone.
