I keep getting random screen tearing while swinging through the city on my Sapphire RX 7650 GRE 8G, why is this happening?

Zipping between Manhattan skyscrapers felt like a nightmare because of these subtle color bleeds and tearing at the screen edges, especially on my 144Hz panel. After digging into the logs, I found the VRAM frequency on the Sapphire RX 7650 GRE 8G was jittering by 15-25MHz under sudden loads, causing sampling misalignments in the 0.1ms range. I tried enabling V-Sync in the driver first, but that added about 18ms of input lag, which made the movement feel sluggish and unresponsive. I eventually went into the overclocking panel, bumped the memory voltage by +15mV, and locked the sampling frequency to a stable 18Gbps. Checking the RivaTuner frame-time graph, those annoying red spikes completely vanished, with frame times settling between 6.4-8.1ms. I actually hit a snag where the screen flickered after the first voltage tweak, but dialing back the core clock by 25MHz fixed it. GPU temps stayed between 62-68℃ with fans at 1400 RPM. Verified everything with 3DMark storage benchmarks, and the rendering errors are gone, keeping frame times locked at 6.4-8.1ms.
