Minecraft can no longer launch with external GPU, but uses integrated graphics instead

The new Minecraft launcher from windows store can no longer launch with NVIDIA GPU, but uses integrated graphics instead, resulting in a massive drop in frame rate.

I am having the same issue.

To elaborate, before the new launcher came out, we had to set javaw.exe to a dedicated GPU either in nvidia settings or windows graphics settings. After the microsoft launcher was released, the java location was changed. I was able to open the folder with "javaw.exe" using task manager file destination function, but setting it to nvidia GPU in both nvidia and windows control panels did nothing. Minecraft is still using intel HD. A possible workaround is using external java but I didn't test it and I don't know what impact on performance that would have.

 Tested in both completely default vanilla minecraft 1.17.1 installation and in a 1.17 fabric profile.

Here is the java location

C:\Users\%Username%\AppData\Local\Packages\Microsoft.4297127D64EC6_8wekyb3d8bbwe\LocalCache\Local\Microsoft\WritablePackageRoot\runtime\java-runtime-alpha\windows-x64\java-runtime-alpha\bin

Changing it to high power doesn't work.

switching to external java fixed it

Hi there! 

Could you answer few questions regarding this issue, it will help with the investigation: 

  • Does this issue occur on newest version of the Launcher?

  • Does this issue occur on Launcher from the old Launcher or the new MS store Launcher?

  • Is your Windows and associated apps (Xbox app, MS store) up-to-date? 

  • Do you use VPN or any of the incompatible software on machine you try to log-in?  

  • Could you provide us with more in-depth repro steps? 

  • Could you provide us with a video recording of this issue?

  • Does switching to external java (as mentioned by Libab Nioblem Mibabilibium) fixed the problem?
