The game does not support Intel Graphics. You will need to have an ATI or Nvidia card.
Yeah integrated GPUs usually mean no gaming.
And even if you have more than enough capable PC, game still stutters and fps plummets from time to time, without any apparent reason. I have applied all performance+ram patches, disabled vsync everywhere, 8GB RAM+1GB VRAM and when game hiccups CPU+GPU+RAM usage aren't even near 100%. I guess it's just the way game was programmed.
You will need a bypass dll to get the game running with an Intel and it may put your hardware and software at risk.
