To my knowledge no official specs have been released; though given it's made on the Unity engine, rule of the thumb are they are fairly low. Though, the water probably creates a lot of CPU Load.
I'd say you need at least a decent Quad-Core Processor. I can run it on one of my PCs with an AMD FX-4130, and it's pretty low end at around 45-60FPS. As for GFX Card? I can't say for sure. Runs fine on an R7 260X with 2GB of VRAM. RAM in general could be an issue, again, due to the water. You should probably have at least 8GB of RAM.

I have a few, a threat other than the shark; something a little more unique, and maybe some defenses to prevent said threats from destroying your Raft. Right now it feels like having to stick the shark with a spear every so often is just annoying micromanagement.
Maybe make the furniture be functional instead of straight up cosmetic down the line, and of course, the more aesthetically pleasing things to build the better.
I also feel the current way of getting materials needs an update, given the early development stage of the game it works for now; but we need something like... Well, why not let your raft actually float out instead of being stationary?
Like, come across wreckage from other ships and so on; and give us a way to anchor our raft, either with a straight up anchor of sorts or a way to pin it to other wreckage, like a harpoon gun with a rope attachment. And, obviously the bigger your raft, the more of an anchor you'll need. Give us a little exploration and the game will go a long way. I feel like this idea will help preserve the game's uniqueness and set it apart from other stranded survival games, while giving the players more things to do; and a more unique method of gathering materials other than just fishing for them with nets and your hook.
The AMD card thing is false, I'm playing with an AMD Radeon card right now. The requirements are fairly light, to be honest; even with an older card like the R7 260X I can run it with a near smooth 60FPS on the highest graphics setting, if I had a better processor I would probably be running it at 60FPS without any stutter.
So, in short, as long as you have a fairly modern GFX card and a decent CPU you can run it with little issue. It doesn't consume a great deal of RAM either.
The "game breaking issue" with AMD cards is probably just out of date drivers or something of that nature. You should, at the very least have driver version 16.6.
