My Gainward RTX 5080 Storm OC has terrible screen tearing during fast turns in Valorant, how do I fix this?

I was seeing obvious horizontal breaks across the screen during fast movements, and at 2K resolution, it was just an eyesore. After digging into the logs, the Gainward RTX 5080 Storm OC had frame times fluctuating between 3-8ms, meaning the GPU output and my monitor's refresh rate were completely out of sync. My first instinct was to turn on V-Sync in-game, but that spiked my input lag to 30ms—it felt like moving through molasses, so I scrapped that immediately. I went into the NVIDIA Control Panel, manually locked the G-Sync range to 48-240Hz, and toggled on Low Latency Mode. This brought my frame time variance down to a tight 4-6ms. I did notice some slight brightness flickering at the edges right after enabling G-Sync, but a quick monitor firmware update killed that issue. Now, VRAM usage stays between 6.2-8.5GB and core temps are a chill 58-64℃. After a few ranked matches, the tearing is gone and VRAM temps are holding steady at 62-66℃.
