Sure, but we’re talking about a handheld. Yes, performance is improving generation over generation, but in the handheld space power usage and heat dissipation are equally important. If you’ve been keeping up with recent innovations, you’ll see that generally we are making more powerful parts, but they’re getting much more power hungry for every little percent of improvement they bring in raw horsepower. So far it doesn’t look like you could even get Xbox series S performance in a handheld yet. At least not at a reasonably portable size, cost, or battery life. You could get a little better than PS4 pro performance in a handheld at present, based on what I’ve seen. Which is not a full generational leap over what’s out there.
Grayjay on Android has been working damn near flawlessly for me. No clue if the parent company is to be trusted at this point or not- but I cannot argue with the results.
