How do I stop screen tearing and input lag in Like a Dragon: Ishin!?

Street brawls had obvious tearing and sluggish inputs. My Vastarmor RX 7800 XT 16G D6 VSync settings were wrong. I tried turning VSync off, but the tearing got worse. That was a regrettable mistake. I used GamePP Power Plan Switcher to enable Adaptive VSync. Frame times stabilized at 12-15ms per GamePP Frame Time Analyzer. Input latency dropped below 8ms. The combat feels responsive and smooth. I backed up the config for future reference.
