Most “normal” programs use some “abstraction” libraries, so the programmer doesn’t need to know which platform it is running on. This “platform” is important because it is the layer that actually talks to things like your SSD, RAM, GPU, etc.
Videogames, tho, are very very specific programs that really benefit from very optimized code, so some of these “abstraction” libraries simply will be worked on for a specific operative system.
Thankfully, the people from the WINE project and lots of work from Valve themselves have made it possible to “trick” these libraries into thinking they are talking to Windows. It’s not perfect, tho, so some stuff is still not working, but you’d be surprised how much we’ve got already. Check out the ProtonDB project.
I did.
Hardware is amazing. I broke the screen after a month (my fault) and the replacement part was official, 40 €, and literally 3 minutes of repair time, no glue, no fancy equipment needed.
BUT Software support is non-existent. Not even security updates. Seems like this is something typical for Unihertz, which is really sad because these guys would become top sellers if they opened up for community contributions to software (Lineage OS or something), because, as I said, hardware is excellent and fairly repairable.
