Yeah, it’s got doom. The frame rate is fairly useless, much like the rest of the device it seems.

Latency is terrible (as in 1-2 seconds to respond to a single key press even in a text editor, let alone doom) and the screen is limited to, iirc, 1 million refreshes total before dying. At roughly fives hours of use per day with a refresh once/second, you’re looking at 55 days before the screen burns out.
