You need a Core i5-650 3.2GHz or Phenom 9850 Quad-Core processor coupled with a GeForce GTX 560 to run Hollow Knight system requirements at recommended. You can expect to get around 60FPS at 1080p screen res on high graphics settings with this hardware. 8 GB will also be needed to achieve the Hollow Knight rec specs and get 60FPS. Hollow Knight needs a graphics card thats at least as powerful as a GeForce 9800 GTX/Radeon HD 4850 paired with Athlon 5600B Dual Core/Pentium Dual Core E5200 2.5GHz CPU to match the min specs. This PC setup will deliver 25-35 Frame Per Second at Low graphics setting on 720p resolution. System memory for min is 4 GB. Make sure your GPU can run DirectX 11.00 or Hollow Knight won’t run. We suggest a 14 year old PC to play smoothly.
