Why is windows 11 not using my gpu?

The game has to be 'using your GPU' otherwise there would be nothing on the screen. What's the CPU usage like?

Your system's Intel Iris Xe is only part of your hardware spec, what's the rest? Is this a laptop or a desktop PC?

Roblox doesn't need high system requirements. However, any game, if you push the system hard enough, can have frame rate issues and low performance. What graphics settings are you using? What's your resolution? Are you plugged into the mains?

No it's a windows issue because on my desktop it can fully utilize the gpu

you have to ask them for Support on their game

Hi,

It's possible that since you updated your graphics driver, Battlefront 2 may have reverted to the integrated GPU. Firstly, make sure it's using your dedicated graphics processor.

You can also force this via the NVIDIA control panel.

It's not always necessary to download the latest GPU driver when a new game is released. These drivers optimise the game sure, but generally speaking, unless your drivers are extremely outdated, it's not mandatory.

This is broken on my laptop on:

Windows 10 20H1

Windows 10 20H2

Windows 11 Stable

Windows 11 Insider Preview (fast ring, 1 week ago)

All on fresh clean installs.

Same test run on a desktop machine on the same network works fine. Ethernet on Laptop does not fix it.

It's got to be something gaming laptop specific, possibly GPU selection. Forcing the Xbox app to use either integrated or discretre graphics didn't work either though.

Switching the GPU mode to "discrete graphics" on my Legion 5 didn't fix this either.
