How to stop screen tearing in Nioh 2 on WD SN850 SSD
This is unbelievable—an action game on my rig felt like it was running on a ten-year-old PC with this much tearing. The WD SN850's 1TB capacity was fine, but the virtual memory was swapping constantly during heavy combat, creating a 15-22ms I/O wait variance that completely desynced the GPU output from the monitor refresh. I tried 'Fast Sync' in the drivers, but while the tearing stopped, the input lag jumped to over 60ms, making the game feel like I was wading through mud. I eventually went into system settings, locked the page file at 16GB, and used RTSS to cap the frame rate at 97% of my monitor's refresh rate. In the frame time monitor, the delivery finally stabilized between 8-12ms, and the tearing vanished. I actually wasted half an hour swapping out three different DisplayPort cables thinking the hardware was broken before realizing it was a disk I/O sync issue. Drive temps are 42-50℃ and RAM usage is around 11-13GB. I've exported the BIOS and system config files so I can restore this if I ever update, and the backup is complete.
