Why is RDR2 tearing during fast turns in Saint Denis at 2K?

Racing through Saint Denis was a pain; horizontal screen tearing during quick turns made the 2K experience feel broken. I tried enabling V-Sync, but the input lag became unbearable, making the controls feel like I was walking through mud. I used the GamePP Image Sampling Calibrator to set sharpening to 68 and locked the render scale to 100%. RTSS confirmed the frame generation curve flattened to 11-14ms, while HWiNFO measured core temps at 56-62℃ and RTSS tracked fan speeds at 1400-1600RPM.
