Your PC will need a graphics card thats as powerful as a GeForce GT 120/Radeon HD 4550 and it should be paired with either a Sempron 3600+/Pentium 4 3.0GHz CPU to match the RHEM 4 recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. For your PC to completely meet the recommended requirements you will also need 512 MB system memory. Make sure your GPU can run DirectX 9 or RHEM 4 won’t run.
