Literally that what I'm pursuing rn, I want to make my first (real) 3d game, I'm very aware of the loophole that most self-made engine game developers falls into but I genuinely found no 3d engine that suits my criteria:
* Be resources efficient (memory and cpu usage)
* Has primary 3D support
* stable
* Supports old devices (ideally embedded systems too)
* And of course be FOSS
I'm focusing on mobile, as you know mobile devices are very sensible to heating so the 1st option is a must, Godot isn't resource efficient, it heats very easily when I play one of the sample games. Regarding the second option, whilst Godot still supports gles2(which is the most widely supported api yet across old devices) it's further being pushed as second-citizent over Vulkan and looking through github no other engine checks my boxes...
If someone could direct me to an engine that checks all the boxes above I would happily try it out.
I've been looking into Stride[0] for a bit and it seems to meet most of your requirements. I'm not sure at all about embedded support but it does seem to treat Linux as a first class citizen for once.
the main up/downside is that it's a C# engine. So it won't necessarily be as hyper-optimal as c++ without some discipline on what parts of the language you use (hint: avoid LINQ at all costs in the hot loop, and look at the newer ways in C# on how to utilize unmanaged collections).
