Unit response sounds lower FPS ingame

StarCraft II Technical Support

Hello,

I have the strangest issue in Starcraft 2. I have noticed a problem while playing that the game is not as smooth as it should be, but I wasn’t sure if I am seeing things or not. Today I was able to replicate the problem and now I know that repeatedly changing between groups (1234;1234;1234, you know) causing unit respond sounds significantly slows down my game and my FPS drop low. The game runs perfectly smooth in big fights, high unit count if only I am not using control groups at all or I have sound disabled/unit response sound disabled. I have tried a lot of things but nothing worked. While this issue is barely noticable in the earlygame, in the later stages this gets unplayable.

After failing with disabling every audio device, reconnecting headphones, toying around with the audio settings I couldn’t find any solution. In the end I have decided to completly reinstall Windows 10 from the scratch and after downloading Starcraft 2 again, the issue still persists. Please help me find a solution so I can play my beloved game.

To help you ilustrate the issue:

  • Sound disabled, spamming hotkeyes = no changes to the FPS

  • Sound enabled, spamming hotkeyes = FPS drop, you can feel small stutters ingame

-Sound enabled, not spamming hotkeyes = no changes to the FPS.

I have gifs, but I can’t post links in here. I wanted to post DxDiag here immediately but then it says my post is too long.
You can find my DxDiag on pastebin dot com / NqWCdkxB

To save us time before you suggest me to turn it off, I have already disabled all windows “capture in the background”, Xbox game bar and game modes settings. This didn’t fix the issue.

I hope you can help,
MaNa

There are a few things you can try to see if they improve this issue caused by sound.

  1. Switch to Windowed mode
    System > Graphics > Display Mode > Windowed
  2. Disable Reverb
    System > Sound > Reverb > Disabled
  3. Lower sound channels
    System > Sound > Sound quality > Low

If the issue persists, please upload your system files to pastebin.com and reply with the links to the files using the preformatted text option to encapsulate the links.

MSINFO is usually a little clearer for some things, but both would be good as they both have pros and cons in terms of what we look at.

If you don’t feel comfortable submitting them here on the forum you can always reach out to our Customer Support team (mention this forum post too if you want so they see what you’ve done): Contact Support - Blizzard Support

It might be worth trying out the latest windows updates as there were some updates related to gaming issues specifically caused by a previous update.

Or they will be available “soon”. :slight_smile:

Hello all,

Sounds like (pun intended) the problem is still ongoing. If it’s still happening and being “solved” by either :

  • disabling the sound
  • disabling the unit response sound
  • reverting to a previous Windows build (1909 and earlier)

Please reply to this threadand with preferably your MSinfo and DXdiag files. You can post them here using the preformatted text for a better visibility. If it doesn’t fit, you can host the files on an external site such as Pastebin then provide the URL here, also in a preformatted text.
