It’s a graphical remaster of Portal 2 that’s mod-friendly and free (but requires the original game in your library). It uses an upgraded version of the Source engine called Strata Source, which also powers Momentum Mod.

I believe they just took Portal 2, put a newer engine under the hood and added a bunch of tools so that people can make mods way easier. One nice side effect is, that it now looks a bit better if you just want to play the campaign.
Portal 2 for its own engine seperate from portal 1 I thought.
Yes, this is in fact true. However, after Portal 2, they kept on working on the engine for CS:GO, Alyx and CS2. That’s why those engines are a bit more modern and add new visual effects and also a lot of new capabilities. They all share “Source 2” as foundation, but I believe each of those games has added enhancements for their use cases. This mod now uses the newest engine of CS2 for Portal 2, which is a jump from 2011 to 2023.
Oh, they switched to Source 2? I thought P2:CE was based on the CS:GO branch of the engine, which would still be Source 1. But I haven’t kept up to date with what they were doing, so maybe I’m wrong here.
I was mistaken; you are right!
