Fair, Satisfactory is a lot heavier on the hardware for sure. But it’s a first person 3D game with a much bigger emphasis on beauty.
I find top down to be less interesting. I like to build factories in 3D with many vertical manufacturing layers in addition to spreading out horizontally. I think 3D factories is a more fun challenge. To each their own though. They’re both interesting games.
On Linux VA-API works really well for AMD video encoding. I have a small home server with an AMD Ryzen 5 5600G and my experience has been excellent.
The only downside is that some companies decided hardware decoding violated some patent and disabled hardware encoding in the default va-api package. You just need to switch to the freeworld version of va-api and everything works well.
If you are ok with a 4-5 hour battery life then this should work. They all have Linux clients. The problem is that there is no notification infrastructure. The phone just runs like a desktop the whole time. If you sleep the phone you don’t get alerts.
