Roleplay 2 is a standalone game that is built off the good old SAGE engine (specifically the version that C&C Renegade used). When the project was first started the aim was to bring Grand Theft Auto style gameplay to C&C Renegade (This was done mostly because back in 2003 when the project was statured GTA didn’t have its own multiplayer yet).
Your PC will need a graphics card thats as powerful as a GeForce GT 340/Radeon X1900 GT and it should be paired with either a Athlon 64 X2 Dual Core 4200+/Core 2 Duo E4400 2.0GHz CPU to match the Roleplay 2 recommended system specs. This PC setup will deliver 60 Frames Per Second on High graphics settings on 1080p monitor resolution. Also your PC needs 2 GB RAM to meet the rec specs and run at 60 frames. You should also have 1 GB system memory for min specs.
