Firefox is slowing down significantly while I have "more" demanding games running

Hello, the description is the same as in the title: Firefox is slowing down significantly while I have "more" demanding games running I'm talking about a game like assassin's creed mirage mostly on ultra for example.

It all started with the purchase of a new computer, on the previous one I did not encounter such a problem. It manifests itself in the way that the video is slightly desynchronized with the sound + I can see a significant difference (delay) when scrolling the pages.

My current rig: Intel Core i7-14700KF Nvidia RTX 4080 32GB of ram running at 6000mhz (G Skill Intl F5-7200J3445G162x16GB ) 2x Kingston SKC3000D2048G 2TB


I understand that the GPU focuses on the game but can't it be improved somehow? The rest of the applications on the computer work normally In my opinion, the computer does not seem so weak that it cannot handle Firefox and the game simultaneously.

Send help please 😊

Chosen solution

You could assign Firefox to a different GPU:

Windows Settings > System > Display > Graphics > Add firefox.exe > Options > Power saving GPU

Or you could shift it to CPU by disabling hardware acceleration.

Most likely this is due to high GPU usage (95%+), when I turn off the game then Firefox returns to fluent work. I understand why it works this way considering the high GPU usage, but is there by any chance a workaround for this?
