Finally fired up Elden Ring too... damn, what a lazy PC conversion. I spent a good 5-10 minutes trying to work out what key on my keyboard was Y because it sure as hell wasn't the Y key. And it turns out all in-game instructions are written for a console controller.
bit late now but in settings under sound and display you can choose 'device for on-screen prompts' and set to either keyboard or gamepad.
Already refunded and playing Cyberpunk 2077 instead. And oh my, I love ray tracing. It's subtle but adds a layer of realism that makes you pause at times.
Flight Simulator has the same "assumes game controller" symptom, but am going to persevere with that one.
