For example V rising used to crash my computer after 10-20min every time without exception until I lowered the graphic quality and disabled unlimited FPS (I set it to 60). Now it works without crashing.

I have a Gigabyte Geforce RTX 4090 that should be able to bear the load of the best graphics settings.

I tried doing the same in Valheim, but it keeps crashing particularly inside my megalomanic castle and the surrounding village (which could be part of the problem). But it also likes to crash while doing mundane stuff like walking through a forrest.

I see many other people having the same issues - they have a high end GPU and some games just keep crashing their computers. And as a counter point, my friend has a low end computer and he never had any crashes with V rising or with Valheim.

So my question is what is causing the issues here? Both games are made in Unity. Is the problem in Unity, developers, the GPU or the combination of all?
