I've only run a few indie games on my lappy with HD 4000 (they all played perfectly), but it plays some of the heavier duty games (SC2, Sins of a solar empire, battlefront). I'm pretty sure those are more graphically intensive than most indie games, and they play great. So yes, HD 4000 is more than adequate for low end games or mid end games on medium to low settings. Make sure you go to the intel driver update website and get the graphic driver updates, that actually make a big difference performance/gaming wise.
