Heroes 5 is a game from 2006 (and development started in 2004). It was made for the budget hardware of that time. The game has 2 GB of video memory; just because you have a modern video card that can handle 8 GB of video memory doesn't mean the game will use it. The game simply doesn't know how. So, if you fill up the allocated 2 GB of video memory while playing on a giant map, the game will crash.
