Hey folks,
While I can’t speak to all of your issues, integrated GPUs are not currently supported, which is why the OP can’t play. You can review the system requirements here.
As I’m not a developer, I can’t speak to whether or not this is going to be changed going forward. If you’d like to see it changed your best bet is to give feedback in #d2r-beta:beta-feedback.
If you do meet the system requirements, please post your own thread in these forums with your specs and what error you’re getting and we’ll see what we can see.
