The best solution I have found so far is to run the second account on my laptop and remote access it on my other monitor. Teamviewer seems to be the client with the least frame drop for this in my experience. I was unable to find any VM that support Direct X12 3D acceleration, so it seems that for any VM solution, while it may launch, the game would run extremely laggy as it would not be able to fully (or at all) utilize your graphics card.
