Intel 3000 HD
I also have an Intel 3000 HD laptop. (They seem to be ubiquitous).
Is there some way to be **informed **if/when you track down this bottleneck in the driver? 
Is there a list some where that is updated with lists of video cards that Unreal supports?
Also, I wouldn’t say it’s “unusable”. Just very very choppy (With the chair scene in Unreal 4.1.1: 8 FPS lit, 14 FPS unlit) . The main choppiness seems to be when moving objects in the scene.
But I’ve suspended my subscription until it gets fixed. Just need to double the FPS and it will be fine!
They’re missing out on a big market if it won’t run well on laptops!
According to the blurb for 4.3 “Unreal Engine 4.3 includes greatly improved mobile support, awesome new rendering features, improved Blueprint workflows, and strides toward an excellent experience on Mac and laptops.”
But according to people in this forum it DOESN’T work well on laptops. I don’t know who to believe!
