It may be, but the bugs and low quality graphics in ED on PS4 is not the fault of the platform, but rather Frontier's inability to optimize for our platform. I've got games on my PS4 that were originally PS3 games (like Tomb Raider Definitive Edition and DD: DA) that look better than ED does. Then play a game like Horizon Zero Dawn (which is actually "old" now) or Spider-Man, and ED just looks sad... I blame you PC gamers for this, because $2000 hardware allows Frontier to get away with lazy graphic shaders
All that said, if terrible shadows was the ONLY problem with ED, I'd be complaining about this over in the PS4 forum. Most of the bugs and half-baked features are cross-platform, which actually makes me kinda glad I only spent $200 on hardware to play this game
Considering my own issues in this regard (I'll let you put two and two together), this would not surprise me, LOL.
