You need a Core i5-2400S 2.5GHz or FX-6100 processor coupled with a GeForce GTX 760 to run GRAV system requirements at recommended. You can expect to get around 60FPS at 1080p screen res on high graphics settings with this hardware. You should also have 8 GB system memory. The best chance at playing this at minimum sys specs on a 1280x720 screen res will be if your PC has at least the GeForce GTX 560/Radeon HD 6850 graphics card. The CPU required to meet minimum requirements is a Athlon 64 X2 Dual Core 4000+/Core 2 Duo E4400 2.0GHz processor. With that PC you will be getting around 30FPS on low graphics and may need to adjust some of the other GRAV graphics options. System memory for min is 4 GB. Make sure your GPU can run DirectX 9.00 or GRAV won’t run. This means you will require a 9 year old PC to play smoothly.
