Min spec requirements for running UMG-only packaged window build?

Hi - I would like to know what is the minimum computer spec for running a UE packaged build (windows)? My project is made entirely on UMG with BP actors containing scripts only (i.e. no mesh, no light etc). Most of my target users will be using low end laptops with integrated graphic card only. Is there a minimum spec for these kind of basic apps?

I tested it on a few machines, they all get the “Know issues with graphics driver” warnings for the intel graphic cards but I understand the warning is just a bug as described in this post: (5.0.3 Hotfix Released). However, some machines are able to run the build without problem whilst some got a fatal error.

Is there specific settings I can change to remove as many computer requirements as possible in the build?

Thanks!
