Failures can be incredibly annoying in any game, but especially in Total War: Warhammer 3. Unfortunately, the current version of the game has a bad habit to fly when Alt-Tab is pressed.
Fortunately, for this there is a pretty simple solution. If you run the game in the window mode, even if this window is deployed, Alt-Tabbing will no longer call the game failure or software blocking. This is due to the fact that it changes the way to determine the priorities of the game and running it in Windows.
To do this, simply enter graphic parameters and select graphics . Go to the option that says Start in the window and select this option, making sure the checkbox is set. When the screen changes, select Save Changes and your game will now work in the window mode.
If you run the game in the window mode, it is better to choose a resolution, a little less than your screen size, as this will prevent slipping or skipping something outside the screen. It will also help you Alt-Tab if you need.
In general, the game is much more stable in the window mode and it seems, passes through most of the software locks and is better free than in full-screen mode. Developer Creative assembly also knows about the problem with Alt-Tab and offers similar measures until they work on correction.
