Dealing with sync issues on Soyo SY-A320D4+ Magic Sound?
That horizontal tear right in the center of the screen was driving me crazy, especially while flying through Azeroth; it made the whole world look like it was breaking apart. It turns out the PCIe bus on the Soyo SY-A320D4+ Magic Sound was hitting a 5-8ms sync drift with my monitor's refresh clock. My first instinct was to toggle V-Sync in-game, but my input lag spiked to a miserable 75ms—it felt like I was dragging my mouse through molasses. I pivoted and disabled in-game sync entirely, opting for 'Fast Sync' in the NVIDIA Control Panel and hard-capping the global frame rate at 59 FPS. The tearing vanished instantly, and my input lag dropped to a crisp 22-28ms. I actually tried capping at 60 FPS first, but there was still this subtle micro-jitter that only went away once I dropped it by exactly one frame. The chipset temp is holding steady between 42-50℃. I ran a sync signal analyzer and the waveforms are perfectly aligned now.
