I wanted to ask if I can play fortnite and steam with a raspberry pi4? Is that basically possible? Is it because of the performance?
No
Nonn
No, unfortunately that will not work.
This is a 4 core ARM CPU with 1.5 GHz
It is very possible to gamble on it and it is very pleasant and fun at night because it runs smoothly
But stop as an emulator. (See retropie)

Many emulatorek offers you a very diverse range of Rome's should of course be legally acquired.
If you are serious about current games like fortnite and then stream, then no
A Raspberry Pi does not shine with performance even in the current version. Especially not if you are using a graphical desktop. When playing games, it depends on the computer reacting without delay. You shouldn't expect that with the Pi. You need a powerful graphics card to play games. The Pi's graphics card is the opposite. There's also no way to connect a graphics card, the interfaces are simply missing.
