MS Teams performance issue - disabling GPU acceleration

Question

We have been struggling with MS Teams performance and one of the suggestions that we found to improve was disabling GPU hardware acceleration.

We are considering disabling GPU hardware acceleration on all of our systems but I have two questions about this.

1- Is this a good idea? What are the implications of disabling GPU hardware acceleration in Teams? IE- what else does it effect? Is there any reason we shouldn't do this?

2- I have searched the web for ways to disable hardware acceleration in Teams on all of our computers (GPO, Registry key etc...) and all I have found is that this setting is controlled via a .json file. Is this the only way to do it or is there an easier way?

Below is the link I found that discusses making the change via JSON file. It's an older article and I'm hoping MS has addressed it with a GPO template or some other means:

Thanks in advance

Hi @Elroy

What are the implications of disabling GPU hardware acceleration in Teams?

There is no obviously impact for your Teams client. It should improve your laptops ability to run Teams client.

Is this the only way to do it or is there an easier way?

Yes, because this is the user settings. User settings for Teams are saved in a JSON file desktop-config.json. If you want to automate this setting for your users, you need to search and replace “disableGpu”:false for “disableGpu”:true. This can be done with a simple Powershell Script. And then let the script run via a GPO, SCCM or Intune.
