WWE 2K14 requires a quad-core processor or higher to handle the game's graphics and gameplay mechanics. A processor with at least 2.33 GHz or 3 GHz will be sufficient for a smooth gaming experience.
The game requires at least 2 GB of RAM to function, but 4 GB is recommended for optimal performance. This will help prevent freezing and other stability issues.
Based on community testing and RPCS3’s official compatibility database (WWE 2K14 is rated "In-Game" with minor graphical glitches), the following requirements are recommended for 720p/30 FPS (the original console frame rate).
To play the game smoothly at 1080p or higher with a stable 30/60 FPS, you will need relatively modern hardware.
