Desktop game runs poorly on Windows 11?

Greetings,

I have a big project which uses many objects and event sheets. My specs:

OS: Windows 10
RAM: 4GB
Processor: Intel UHD Graphics

I exported my games to Desktop (Windows, .ZIP) and when I Iaunched it, the game works PERFECTLY fine without any noticeable lags.

Then, when my friends want to playtest the game, the game lags insufferably (playing the same exact build). My friends’ specs:

Friend A
OS: Windows 11
CPU: AMD A4
GPU: AMD R3
RAM: 16 GB

Friend B
Acer Aspire
OS: Windows 11
RAM: 8 GB

(These specs are the only information that I could obtain from them as of now)

Both of them claimed to have suffered a tremendous FPS drops and lags when playing the exact same build I played. My hunch is that the problem is with Windows 11 but I am not too sure. How is my DELL laptop with integrated intel and a 4GB RAM can run the game build so well compared to my friend’s beastly laptops?

Is this common?

Thank you for your time.

Maybe their GPU doesn’t recognize the game?
