Thanks for reply,
Had a feeling this might be the issue.
Stretched the PC to the last.
Have to say, it performed well on all games up to now.
Like everyone, we will all be eventually decommissioned, retired
and thrown on the scrap heap.

Anybody else have this fault.
Any fixes available.
Cannot play DayZ or Arma3 anymore!!!

No, experimental crashes exactly the same way.
Tried my Arma3 and this also crashes with the same error when attempting to log in to server.
Seems to be a common fault.

Game crashes during load in to server. Do not get to start game at all.
