The bug in the software meant that when it ran in the background, the graphics card will fail to hit the maximum memory clock, leading to a performance loss. It only harmed the memory subsystem on Nvidia cards.

Discord recently enabled AV1 support for Nvidia's latest GeForce RTX 40-series (Ada Lovelace) graphics card, so the bug could be potentially related to AV1 encoding support for video streaming. 

Whatever the cause Nvidia has fixed the issue with an over-the-air (OTA) update which means that its users will get the fix pushed to them without them being aware of it. If you want to make sure Nvidia has shared the following method to solve the Discord application bug manually:

1. Click here(opens in new tab) to download the NVIDIA program GeForce 3D Profile Manager.

2. Open the GeForce 3D Profile Manager.

3. Click on the button Export SLI Profiles.

4. A file explorer window will pop up. Select a location to export and save the NVIDIA Profiles text file.

5. Open the text file saved in step 4 using Notepad (or any program that does not automatically apply formatting).

6. Perform a search for the section "Discord." Add a new line and type the following text as shown in the screenshot below:

7. Save the edited NVIDIA Profiles as a txt file.

8. Go back to the GeForce 3D Profile Manager and click on the Import SLI Profiles button.

9. A file explorer window will appear. Select the updated "NVIDIA Profiles.txt" file and then click on the Open button.

10. Once completed, you may close the GeForce 3D Profile Manager application.

Personally, life is too short and I would rather wait.
