I'm was talking about game stability. This is a gaming related topic right? Linux is stable but games had some issues.
Truthfully nothing major that stopped me from playing but I had to mess with proton in steam from time to time. Most recently the Last of Us crashes on start, not sure why it was fine previously. Also, there were some games anti cheat did not work and I needed to play in Windows.
Also, I have consistently had issues streaming to my steam Deck. Windows isn't perfect either but it's more likely to work the with windows. Sure maybe it's my Nvidia GPU, but saying switch to amd does make my setup more stable.
Also in the US the plans had free unlimited sms early on and people just stick with it. They know a number will receive a text message they don't on now if they have Whatsapp.
This is the big issue I have with with "USB C". USB c is just the connector which can be used for so many things. What actual is supported depends on things you can't see, like the cable construction or what the device supports.
How are you playing FTL on the deck? Are you using the track pads or a custom controller setup? I struggled to find an easy way to play with the controller.
While it works Wifi isn't great for control. You need a stable connection without jitter.
