To run Kingdom Hearts III on high graphics settings your PC will require at least a 8GB GeForce GTX 1070 / Radeon RX Vega 56 8GB with a Core i5-7500 3.4GHz or Ryzen 3 3100 4-Core 3.6GHz CPU. Kingdom Hearts III needs a Core i5-3330 3.0GHz or Ryzen R3 1200 processor coupled with a GeForce GTX 760 to get it to run minimum system requirements. This will return around 30FPS at 720p screen res on low graphics settings, but you can also adjust the settings further to tweak. To be able to run at all you will need at least 8 GB system memory. Your GPU is expected to be able to deliver DirectX 11.00. In short you need a 6 year old PC for best Kingdom Hearts III performance.
