Not to assume you play games or watch YouTube, but on low DPI you also don't realise what you are missing in detail. Entire objects reveal themselves in this new space between the pixels. Where once was a splodge is now a person far off into the distance. You could almost liken low DPI to being near sighted, which I also am. Once you hit higher DPI suddenly you can see the view far off into the distance clearly.

I have been messing with VR lately and that is a new dimension as well, similar in change to the jump to high DPI. Ignoring the stereoscopic part, you also don't realise the scale of things until they are in the correct FOV in front of you. I see now why simracing boffins faff about with FOV so much on their screens! I took the effort to calculate FOV for my desktop monitor and where I sit, and in FPS games and it made a huge difference to immersion.

Oh man, I never got into gaming because two of my brothers were so off-the-charts that I was like “why bother”.

When I was like maybe 19 there was this Quake3 player who went by Zero4 who was in the top few on Earth at that time, and my 16 year old brother slapped him around so effortlessly during their biweekly workouts I knew that it was going to be more fun to watch than to be 1-px railed before I figured out which gun I was holding :)

I do hear that actually, my little brother plays and there is a pretty big age gap there, so he has unlimited energy and time and I do not. He plays so much better than I can manage, and I just don't have the time to commit to it anymore. I still play for fun though.

I've actually got a fair number of recordings of his old matches against the heavy pros of the time. I've ground it through some software and I've caught him getting a shot off in as little as 80ms. That's not even possible I don't think, but I quintuple-checked it.

Even if I'm off by a factor of two he was faster than an F22 pilot, by a lot.
