RE Engine: Monster Hunter, REMakes, DMC. All run beautifully
Idtech: Doom 2016 and Doom Eternal are super optimised on low end hardware
Then you have Unreal Engine 5 which needs top end hardware to run (Remnant 2, Lords of Fallen) and
Gamebryo/Creation which still has bugs from Morrowind in Starfield.
Not sure if related but City Skylines 2 needs several times $$ investment for slight improvements over Cities 1 on Unity
Now a splash screen either makes me smile or cringe. Just wished everything ran RE engine
Optimization is extremely complex and the game engine, while factoring into the equation, doesn’t determine if something is optimized or not inherently.
Yes, this is all a horrible post, game engines can’t really be compared directly. There is no one size fits all.
EA thought that and tried to apply Frostbite to their entire catalogue. What worked amazingly for Battlefield/Battlefront was a disaster for Dragon Age: Inquisition, Mass Effect Andromeda, and let’s not forget Anthem. Engine was optimized for small maps and quick gameplay, but was horrible for large open worlds and RPG elements.
The reason Unreal requires such heavy hardware is because they’re trying to be a one tool fits all, but that requires making sacrifices.
OP’s entire post here is incredibly naive. It’s apples to oranges.
