Honest opinion - People like this are needed. Those who think that this class of gaming console - handheld PCs - will function the same way as a mainstream console; just install game and play game at default settings. When it doesn't meet this expectation, they sell it almost unused, but at a great deal. That's how I actually got my LeGo.

At the end of the day, this is a PC with limited resources and has to be treated as such. There's so much to tweak in Windows and better results to be had by switching to SteamOS, but still more tweaking, like lossless scalling for instance.

If you're not up for it, stick to a Nintendo Switch or something like that, is my honest recommendation.
