What are the common complaints with the graphics? Is it a technical issue (pop in, low textures, etc) or an art issue? Personally, I really like the style of this game because I don't think every game should strive to be ultra realistic. From what I have seen, I would call this game visually stunning.
However, if it's an execution issue regarding simplistic tuning features in favor of advanced options and a crappy engine with terrible pop in and unexplainable framerate crashes (that may or not be fixable with patches and GPU driver updates?), then I can get that. I can see smooshed textures being a problem as well--but that can partly be an issue of the style: primary colors with simpler models tend to be common with this kind of visual style, but I'm not sure why we don't normally see more defined textures in some of these cases?
The art style is good (in the same way The Witness & Firewatch were good whilst not necessarily being textural showcases), but the four common issues I saw were:-
1. Chronic pop-in (to the extent you often don't see some stuff until you're on top of it)
2. Many have commented the game appears to render lower than what its resolution settings give the impression of. I ran at 1080p and quite honestly, it could have been running 720p and look no worse. Things do look a lot blurrier than certain pre-release marketing screenshots.
3. Rendering glitches that impact gameplay. Eg, after completely exhausting every scrap of a mound of Emeril, after leaving and then returning later it was still visible from a distance until you walked right up to it then it suddenly disappeared. It's like the game only checks for stuff actually "being there" only when you're within 50-100m of it to avoid bogging down the CPU. Likewise, the random generation spawned one building in the water on one planet, and regularly had rocks floating in mid-air on others.
4. Random stutter all the way down to 11fps despite CPU & GPU usage being well below 100%. It felt like an engine limitation and is widely commented on and seems to occur more when using the mining laser / weapon.
