You need a Core i5-650 3.2GHz or Phenom 9850 Quad-Core processor coupled with a GeForce GTX 560 to run Hollow Knight: Silksong system requirements at recommended. You can expect to get around 60FPS at 1080p screen res on high graphics settings with this hardware. Hollow Knight: Silksong needs a Pentium Dual Core E5200 2.5GHz or Athlon 5600B Dual Core processor coupled with a GeForce 9800 GTX 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. System memory for min is 4 GB. Make sure your GPU can run DirectX 11.00 or Hollow Knight: Silksong won’t run. In short you need a 14 year old PC for best Hollow Knight: Silksong performance.
