I first found out about dungeon keeper through reading an old Sailor Moon Fan fic called "Dungeon Keeper Amy". This game is solid. And it still holds up all these years later. Especially the sound effects, the atmosphere, and the music. I absolutely recomend this game.
If you set all the quality presets to low, you can get 30 to 40 fps with a iGPU I have an i7-1355u and I was able to get 40 fps in area's with lower crowd density. Though the FPS did dip to 23 fps during combat encounters. But the game is still playable without a graphics card. CD project reds optimization team has put in some truly impressive work.
