How to fix screen tearing on Manli RTX 5060 8GB?
I noticed this bizarre horizontal rip across the screen, and it was absolutely nauseating during fast sprints. Looking at the logs, the Manli Nebula RTX 5060 8GB has a pretty aggressive factory overclock, which caused a micro-second desync between the driver sampling rate and my monitor's 143-145Hz refresh rate. My first instinct was to just toggle V-Sync in-game, but that added a massive 40ms of input lag, making the controls feel like I was playing in mud. Instead, I went into the NVIDIA Control Panel, stripped all 'enhancements,' and manually locked the refresh rate to exactly 144Hz while forcing the sampling rate to a 60Hz integer multiple. Using GPU-Z, I saw the frame interval stabilize at 6.9ms, and the tearing vanished completely. I did have a couple of crashes during large scene loads because I was pushing an aggressive undervolt, but adding a 0.02V offset fixed it. Core temps are sitting at 64-69℃. After a 4-hour stress test, the sync is perfect and VRAM temps are holding at 58-63℃.
