You need a Core i5-750S 2.4GHz or Phenom II X4 965 processor coupled with a GeForce GTX 750 Ti to run GRIS system requirements at recommended. You can expect to get around 60FPS at 1080p screen res on high graphics settings with this hardware. 6 GB will also be needed to achieve the GRIS rec specs and get 60FPS. GRIS needs a graphics card thats at least as powerful as a GeForce GT 430/Radeon HD 5570 1024MB paired with Athlon 64 X2 Dual Core 5000+/Core 2 Duo E6750 2.66GHz 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 GRIS won’t run. We suggest a 8 year old PC to play smoothly.
