I’ve run probably over 100 games on my steam deck and only run into a single game that I had to move from my SD card to my SSD. Unless you really want to tinker, I would 100% just stick to an SD card

I haven’t played B4B or a PS4, but in general I have a way easier time playing FPS games on the deck than on other controllers because of the trackpads/gyro. It makes a huge difference.

Now, the small screen can definitely be a problem, but that is entirely dependent on what game you’re playing. Some shooters just don’t work well on a small screen.

I would go to protondb and see what other deck users have said about B4B on the small screen.

Same thing happened to me. I was glad to see in the OLED version they redesigned the buttons
