Game crashes to desktop frequently

Of course:

-Diablo IV has run out of memory - #103 by DTMAce-1687

If you aren’t sure (and I don’t know your memory amount or GPU ram amount) set both min and max to 32768. The values suggested in the link are before VoH launched.

If you had say 32GB of memory and an 8GB video card, you can use less for the swap.

You can monitor Virtual Memory usage:

  • Open Task Manager
  • Click on Performance
  • Click on Memory
  • Look for “Committed”
  • You can leave it open here while playing and occasionally Alt-Tab to check on it. If the in-use amount nears the total amount, you may need to set the swap higher.

Committed represents the total of your Physical RAM and the swap file that is set. The game is VM hungry, so often the automatic system in place simply cannot keep up and fails.

Setting it to a static size prevents it from running out. The game does eventually stabilize.

You can also provide a copy of the Fenris log using pastebin.com for me to review as I suggested earlier.
