Custom mesh visible on 2 pcs but not on third one

I'm working on a project involving a custom mesh. I am using a compute shader to offload mesh calculations to the gpu. Also using HDRP.

My pc with windows 10 nvidia 1660, 16 gb of ram and a ryzen 3600 cpu runs it fine. My 8 year old laptop struggles a bit but it shows the mesh.

My friend's laptop with nvidia 1660 ti, intel cpu and i guess 16 gb of ram, on windows 10 doesn't show the mesh. It's invisible, but he can still rotate the camera inside the game.

All of the drivers have been updated on all devices.
What's the deal?

 

if is a laptop make sure that your friend actually use the GPU and not the integrated graphics from the processor the intel hd graphics, those may not support all graphics functionality or the way unity implemented may not work the same on the integrated graphic chip versus the nvidia GPU.

so your code may fail on the intel cpu integrated graphics.

 

Thank you.
Is there something I have to enable to force the use of GPU. Since 2 of those pcs where the mesh is not being loaded are running GTX1660ti and HD 5850.

 

this I don't know.

first check if indeed the game runs on the intel GPU. The user may chose to use a particular GPU on purpose or maybe because he did a mistake when editing nvidia or the intel GPU application. Or maybe the computer decided your game is best suited for the intel gpu. go figure why.

but this is just my hypothesis. first you need to check if is true. one simple way is to right click on the game exe and under the "Run with Graphic processor" see what option have the default name added. then run the game with one or the other see if anything changes
