Game not starting properly (8.1, mobile dedicated graphics)

@Blizzard:
There is already a post on this topic, but as in this post different topics are discussed, I wanted to create a new post on one of these topics. I fear that you are not aware of one of those issues that affect a lot of players.

The issue has to do with mobile switchable graphics.
Since 8.1, the game does not load properly. It shows a white screen and does not respont for ~15 minutes until it starts acting as normal. After starting, when accessing the settings menu, the game crashes again.

The issue persist if one choses to play the game on a dedicated gpu on a mobile device (notebook). Switching to the processor gpu (e.g. Intel HD 4000), the game starts (of cource on low graphics and low framerate).

The playerbase would like to know if you are working on a fix for mobile devices?

Moreover, the fix needs to be done with an update, as it is not caused by the local machine of the player, but rather by the Wow-client after the patch 8.1.

Please note:

  • There is no issue with the gpu driver or the player machine, so you do not need to post links on how to update drivers
  • The game worked properly before 8.1
  • It seems to be connected with notebook switchable graphics

Thanks a lot for your support!
