My Godot 4 2D game is running badly on HTML5 on some PCs

Godot Version

4.2.1

Question

My game is a pretty simple top down shooter, I tried exporting to HTML5 on itch.io and the game runs fine on certain PCs but not others ?..

when running the game on my computer with this CPU “Intel(R) Core™ i5-4590 CPU @ 3.30GHz 3.30 GHz” and 8 GB ram and no graphic card:

*game.exe runs completley fine

*game on HTML5 runs completley fine

when running the game on my non gaming laptop with this CPU “11th gen intel(r) core™ i5-1135g7 @ 2.40ghz 2.42 ghz” and 8 GB ram and no graphic card:

*game.exe runs completley fine

*game on HTML5 runs completley fine

when running the game on my laptop that’s more suitable for gaming with this CPU “intel(R) core™i7-5500U CPU@ 2.40 GHz 2.40 GHz” and 12 GB ram and this graphic card “Nvidia GeForce 940M” :

*game.exe runs fine but the graphics are blurry ?

*game runs slowly when more objects appear on screen and graphics are also blurry

I’m not sure why exactly ? I was expecting it to run best on my gaming laptop but it ran worse, The game is being rendered in compatibility mode too

In Itch.io I have it set to be Embeded in Page and I manually set the Size, for the Frame options I turned on full screen and shared array buffer support

apparently HTML5 cares more about the CPU rather than the graphics card so I’m guessing that older CPUs struggle to run it more ?

Sorry if I’m misunderstanding something about HTML5, I’m still new to this, What can i do to make the game run well on all devices

EDIT : I tried switching from Firefox to chrome but now the game doesn’t even start on HTML5 because some sort of .pck file seems to be missing
