The vessel you're operating on is a cargo ship, and your freezing point is in the Arctic region.
I'm late to the party but here are my two cents: Waiting is always a good option with Star Citizen but the "minimum" of 45 fps which you want wont be a thing even in 3.2. With a Ryzen 1700x, GTX1080 and 32GB of Ram I'm getting 18-35FPS no matter the resolution or settings so 45 will be unrealistic. I've played it with 8GB before my ram upgrade and the performance difference wasn't that big. But if you want quality gameplay wait until further into the development because you can currently get a maximum of 30-40hours of gameplay out of the game and that with poor performance.
Check if it uses an SSD for better performance. This improves playability significantly compared to a standard HDD, though it doesn't affect FPS directly.
