The 4530 is not a powerful card. Still, I don't see why the game would be unplayble
PC Recommended Specifications:
Windows Vista®/Windows® 7
Dual Core 2.4Ghz Processor
2 GB RAM
512 MB NVIDIA® GeForce® 8800 GTX or ATI Radeon® HD 3870 or better
The 3870 was a high-end card in it's time, near the top of the 3000 series; Your 4000 series card is bottom-middle end for that series. It [your GPU] would be outperformed by the 3870, can you play the game at all? You should get decent framerates on medium-low settings.
