Gaming at 1080p and 120 Hz on a Raspberry Pi 4
I often like exploring what's possible on a Raspberry Pi (or other low-end hardware). One area I haven't explored much is GPU performance. I typically run my Pi's headless, and have only dabbled in embedded machine vision with Pi cameras, so most of my experience is on the programming / software side.
But seeing Apple's 120 Hz 'ProMotion', and ever-higher refresh rates in the enthusiast gaming realm (we may hit 480 Hz soon!), I wanted to see how a tiny Raspberry Pi could perform in this realm.
The Pi's VideoCore GPU can output 1080p at refresh rates up to 120 Hz—at least there's a setting for it. But I'd never tried it. The hardest I pushed a Pi was 4K at 60 Hz for my Pi 4 a Day challenge, and that didn't go as well as I'd hoped.
