Hi eric, it's probably something to do with the Intel graphics driver - possibly more due to the software driver itself than the actual graphics card though.

The first thing to try would be to see if there is any newer graphics driver available.

The next thing to try is to disable multi threading in the MoI display engine and see if that avoids some conflict that's happening with the display driver. To do that you need to open up the moi.ini file and change the DisplayThreadLimit= option in the [View] section to DisplayThreadLimit=1

[View]
DisplayThreadLimit=1

It also might be possible that v4 would work better on his system than v3 - v4 uses the newer Direct3D11 interface to the graphics card and that part of the graphics driver may be working better than the Direct3D9 interface that MoI v3 uses. To test v4 on his machine, copy your v4 install directory C:\Program Files\MoI 4.0 beta Dec-12-2017 onto a USB key and also copy your license key files from %Appdata%\moi onto the USB key too alongside MoI.exe then you can run it on his system to test it.

If none of these things makes it any better than it's probably that the graphics card is just not up to it. Unfortunately those all in one systems probably don't have any way to upgrade the video card.
