You heads up i found a thread on intels forums concerning your game which I have also posted to.

https://community.intel.com/t5/Intel-ARC-Graphics/Company-of-Heroes-2-Graphics-bug/m-p/1709587/thread-id/28113

I am going to drop more detail in that thread, but basicly i just started playing the game today.
Game has issues with
1) FMV desync and audio and game engine, on movie sequences.
2) mild graphical artificats on zooming out and camera rotation. game still playable at least so far it is.

I did some file drops in intels thread. that post requires intel mod review and approval should be there soon.

EDIT there a link to a second older thread also.
