Fixing image sync issues on Colorful GT1030 Gold Edition in LoL
I was seeing these dense horizontal tear lines across the screen, which made fast kiting and dodging feel like a chaotic mess. Looking at the logs, the default drivers for the Colorful GT1030 Gold Edition had a random sync offset of 5-12ms when outputting at 60Hz. I first tried turning on V-Sync in-game, but the input lag jumped to 40ms—it felt like I was moving through mud, which is totally unacceptable for a MOBA. I did a clean wipe of the drivers using DDU, installed the latest stable build, and flipped 'Low Latency Mode' to On in the control panel. RTSS showed the frame time jitter dropping from a wild 16-35ms range down to a flat 12-15ms, and the tearing just vanished. I did hit some minor FPS drops right after enabling low latency, but switching the power management to 'Prefer Maximum Performance' fixed it. GPU temps sat between 55-62℃ with fans at 1200 RPM. Confirmed signal alignment via analysis tools; the glitch is finally gone.
