I recently download the game on my PC but when I tried to run it a window pops up, and it says "CRY ENGINE 2
unsupported video card! Intel (r) 82945G Express Chipset Family.
continuing to run might lead to unexpected results or crashes".
you have an IGP, video card built onto the motherboard.
You don't have the power to play the game...
you need to have a discrete graphics card (Nvidia GeForce, AMD Radeon) to run that game.
Read the minimum hardware specs:
