I'm seeing terrible screen tearing during high-speed flight in Genshin Impact on my Colorful B760M; how do I fix this lag?

That horizontal tear right across the center of the screen during fast movement was driving me insane, making Teyvat look like a broken mosaic. I traced it back to the Colorful CVN B760M FROZEN WIFI D5 V20; with XMP enabled at 5600MHz, there was a slight sync clock offset creating a 3-5ms gap between the output signal and the refresh rate. I tried turning on V-Sync in-game, but the input lag spiked to 65ms, making the controls feel like I was wading through mud. Instead, I went into the BIOS and manually locked the RAM frequency to 5200MHz and enabled Fast Sync in the driver panel. The tearing vanished completely, and input lag dropped to a crisp 18-24ms. I still felt some micro-stuttering until I bumped the memory voltage from 1.25V to 1.30V to stabilize the signal. VRM temps are sitting comfortably between 48-55℃. I verified the output waveform with a signal analyzer, and it's perfectly aligned now.
