How to fix screen tearing on Seagate Firecuda 530 in Once Human?
That horizontal tear right across the center of the screen is an absolute eyesore when sprinting, totally killing the immersion of the survival experience. Digging deeper, I realized the Seagate Firecuda 530 1TB was hitting a 6-10ms deviation between high-frequency random reads and the GPU render clock. My first instinct was to toggle V-Sync in-game, but that was a nightmare—input lag spiked to 60ms, making the mouse feel like it was dragging through glue. I pivoted and disabled in-game sync in the driver panel, opting for Fast Sync instead, and forced the disk I/O priority to High. In terms of feel, the tearing vanished completely, and input lag dropped to a snappy 18-24ms. I did notice some minor micro-stuttering after the first lock, which didn't go away until I pinned my virtual memory at 32GB. Now the drive runs cool at 42-50℃. I verified the output waveforms using a sync analysis tool, and the tearing is gone—the response time is finally tight and responsive.
