So I guess for now UE4 is (still) aimed at creating AAA type games for consoles, PC and Tegra powered smartphones. Rather than for developers making indie games in Starbucks on their laptops. Which I suppose they should use Unity3D instead. Which is kind of confusing as the new price system seems aimed to be affordable to indie developers. Oh well. I’ll stay tuned anyway as I’m interested in how the Blueprint system evolves. And I can still experiment with the blueprints despite the sluggish framerate. 
Strange thing is I don’t know many people who actually OWN a PC these days - apart from my friends who work in games companies! (Why would you if you can run Batman Arkham City on your laptop?) They’re kind of on the way out.

This is like the age old problem of the games companies having the fasted most up to date computers to make the games on to improve productivity but then finding out most of their customers have slower computers. I suppose it was OK when Unreal engine was just an in-house product or they were just selling to other large game companies. But I think targeting the wider indie game making public, they might have to consider a different strategy. Those are my two cents worth. 
Also I would disagree that Intel 3000 Graphics is particularly slow. It is faster than some desktop dedicated graphics cards of just a few years ago. It can run things like Batman City, and Spore, and Unity3D. It can do HD video editing. What I would call slow would be an iPad 1 or an Android phone. But I suppose we have different definitions of what is “slow”. In fact I read Intel 3000 is roughly equivalent to the XBox 360 graphics. Hardly slow.
Here’s Skyrim working on Intel 3000.
