Not even close to the same thing. One is running on an engine that would require a heavy rewrite. The other is running on an engine that is fantastic but the game's coding needs optimized.Don't bring up SSE because that's different as well. That's based on CE 1.0 but upgraded to a point between CE 1.0 and Fallout 4's CE 2.0. It's a lot better optimized in many areas, but at the same time it doesn't include a lot of fixes and tech that CE 2.0 has (multiple light sources being one). There's a lot of bad implementation in CE 2.0 unfortunately that for some of the things they did bring to SSE, it works a lot better. God Rays being one.
