At the moment a feature to collect stuff in the world to put it into your home base was not implemented because of this. You want more of those limitations?
And I explained that this might not be possible with trees. Not if they want them to have a comparable quality and style to the rest of the game. They can't make bushes look great and 3D and at the same time have trees as 2D potemkin card board images. Or lets rephrase that as "they could but surely won't"
I understand that but what is the reason for those to have high poly count at all?
Looking at how a coffee pot looks like ingame its nothing too fancy to justify having high poly count compared to for example a generator what player can actually make and may place more than 1.
It reminds me of that infamous skyrim mod what boosts fps by simply removing freacking thousands of meaningless clutter/decoration items. Seriously if something whats basically nothing but a container causes problems in the game it should be removed/remade. Seriously who is going to notice if TFP decreases the poly-count for it?
I think you're looking at it backwards. The coffee pots aren't holding back performance, because the devs only use them sparingly. There's no problem with the coffee pots as is. They'd only be a problem if they were craftable, and craftable for cheap. All that removing the coffee pots would do is mean less decorative 'flavor' items to make rooms and buildings seem less generic.
It is important to remember as well that coffee pots and most "problematic" blocks can be modded to be craftable and adding a recipe for a block is among the easiest modding there is. They don't want to keep these things out of the hands of the players. They want to provide a stable environment that makes playing the game enjoyable for the widest range of gaming rigs as possible. It's the same with environmental spawns of zombies. If you want to increase the spawns by 2x 4x 8x or more you can do it quite easily. But, TFP isn't going to make it be default because they can't guarantee that people running their minimum required specs will be able to have a stable game if they do it.
If you want a coffee pot recipe then create one and add it. Same goes for any block that is restricted from being crafted in the default version of the game. If your rig can handle it then do it. The devs are designing for a community of players and not specifically for you and your specs. It might be frustrating being limited by others with less powerful machines than you but you really are just limiting yourself if you refuse to add a few recipes to your game for things you want or doubling or tripling the zombie spawns if your rig can handle it on some misguided belief that these things SHOULD be in the default version.
As for loot respawn, you can try this video. I haven't watched this one yet but did watch his earlier one. I think this one is updated for A19 and one I watched was done in A18.
This one also accounts for vertical loot from you (like upstairs in a building) from what I can tell.
