Game running unplayably slowly

  • For some reason, in the past few weeks my D3 game has begun to run really slowly, frustratingly slowly, unplayably slowly.
    Occasionally it runs as well as it ever did, but for the most part it is really struggling to run in a playable fashion.
    I haven't changed any of the hardware on my PC and all my drivers are up to date.

    Can someone tell me what issues may cause the game to slow down so drastically.
    All other functionality of my computer seems unaffected - streaming YouTube, watching videos, Internet browsing, etc all seem quite normal. Only D3 seems to be problematic.
    Any ideas?
  • Could you please post some information about your computer? You can find this information in the Direct X Diagnostic Tool:

    Press Windows Key + R.
    Type DxDiag and press Enter.
    In the DxDiag window, at the bottom, click Save All Information.
    Name the file "dxdiag" and click Save. (note where it's been saved so you can find it)

    Locate the Dxdiag.txt file just created and open it to copy and paste ALL of it's contents into your reply.
