This Steam Next Fest killed Unreal Engine for me.
Every single game with that splash screen ended up as a slide show, and not even prettier, I play 15 years old games that look better than most games I saw coming from UE5.
I used to recommend Unreal 4 for everyone, but they are already going for 6 without optimizing the 5.
No need to upgrade, just give a chance to other games, devs and engines that cares for their customers.
I got into Cassette Beasts a while ago and notice all Godot games run well on Steam Deck and my older hardware. Cry Engine looks beautiful and still run well on stuff.
