Your PC will need a graphics card thats as powerful as a GeForce GTX 560/Radeon R7 360 v2 and it should be paired with either a FX-8320/Core i5-2550K 3.4GHz CPU to match the Struggling recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. Struggling needs a Core 2 Quad Q6600 2.4GHz or APU A6-3620 Quad Core processor coupled with a GeForce GT 340 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. In short you need a 6 year old PC for best Struggling performance.
