Your PC will need a graphics card thats as powerful as a GeForce GTX 760/Radeon R9 380 and it should be paired with either a Ryzen 3 2200G/Core i5-3570K 3.4GHz CPU to match the Surviving the Aftermath recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. Surviving the Aftermath needs a Core i5-2500K 3.3GHz or Phenom II X6 1090T processor coupled with a GeForce GTX 580 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. You should also have 4 GB system memory for min specs. You will require a DirectX 11.00 GPU. In short you need a 8 year old PC for best Surviving the Aftermath performance.
