I think that’s a really key point - back in the days of the PS2 to 360 era, it was all about Xx_Graphics_xX and there were so many 30fps games that dipped to 15 at times, making “30FPS” feel worse than it was.
That said, 30FPS can still be rough. IMO Dragons Dogma 2 running at 30 on the PS5 is pretty rough. Even excluding dips, but it has them. But the game Heroes Hour on the Steam Deck running at 30 is perfectly fine. Similarly, setting Red Dead 2 to get a consistent 30 is fine too.
Consistency is huge, for sure!
Power, Domain Name (if using a standard paid one instead of the cheaper route), VPN are the 3 that I pay for that I feel are the bare minimum.
I pay for a domain that’s $12, but you could easily get the $1 ones for the same purposes. I pay for a static and service VPN with Windscribe, which comes out to be like $35+$89 respectively. So that’s already $136 a year excluding the cost of power. I could cut that cost easily, but I use them for more than just my selfhosting so I feel like it’s a fair price for what I get out of it.
