How to fix WD SN850X 2TB I/O overflow in Apex Legends?
The texture loading in this game is a joke. Walls just turn black and then snap back into existence. My 2TB drive was actually dipping to 60MB/s read speeds in some spots. The WD SN850X 2TB hits a wall when handling ultra-high res textures because the SLC cache recovery kicks in, causing random read latency to jump between 15-40ms. I tried dropping the resolution to 1080p, but the game looked like a blurred mess—absolute torture. I eventually went into system settings and locked my virtual memory to 32GB manually, then dropped the in-game texture filtering from 16x to 8x. In Resource Monitor, the disk active time finally settled between 12-22%, and the texture popping just stopped. I did notice the system boot took 3 seconds longer after the VM change, but disabling 'Fast Startup' fixed that. Drive temps are 45-52℃ with fans at 1300 RPM. Exported the read curves to verify, and the scheduling is finally stable. Still feels a bit janky in some maps, but it's playable.
