How to fix screen tearing with Crucial DDR5 4800 in The Last of Us Part 1?
It's unbelievable that a next-gen title could feel like a game from ten years ago on my rig; the visual tearing was so bad I almost uninstalled it. My Crucial 4800 MHz RAM was hitting a 16-22ms sync deviation when handling high-refresh data streams, leaving the monitor and GPU completely out of step. I first tried 'Fast Sync' in the drivers, but while the tearing stopped, the input lag jumped to over 65ms—it felt like walking through mud, which was a total disaster. I went into the BIOS, tweaked the primary timings to 40-40-40-77, and used RTSS to lock the frame rate at 97% of my monitor's refresh rate. The frame time finally stabilized at 9-13ms, and the tearing vanished. I actually wasted half an hour swapping three different cables thinking my monitor was dying before I realized it was a memory sync issue. Memory temps are 48-54℃, and CPU usage is around 60-68%. I exported the BIOS profile so I can restore this if I ever update, keeping the frame time at a solid 9-13ms.
