I've always read some things about soft caps, what are those? I heard anything above 1 million energy gets reducing returns or something?
I recommend that you bookmark the
Official Starmade Wiki. It's not always accurate, but it does a decent job of giving you the basics.
The Wiki has a subsection dedicated to
power generation and also one dedicated to
weapon systems.
The power soft-cap increase is roughly a year old, having been doubled from 1 million to 2 million approximately 12 months ago, in
update 0.19519.
Soft Cap: This is an upper limit of a value after which, you can still add, at a very basic rate.
Example from the
Power Generation Wiki entry on efficiency analysis:
100 reactor blocks placed in a row will give a per-block efficiency of approximately 300.
200 reactor blocks placed in a row will give a per-block efficiency of approximately 400.
1500 reactor blocks placed in a row will give a per-block efficiency of approximately 1300, and will very nearly reach the softcap of 2 million e/s.
After you have enough reactors to reach the 2 million e/s softcap, each additional reactor block adds 25 e/s to the overall power generation, instead of, say, 1300 e/s. So when you add additional blocks above the softcap, the average power efficiency over all blocks starts dropping again.
So you can reach 3 million e/s, but it will take 40,000 additional reactor blocks on top of the original series of blocks that were needed to reach the 2 million e/s softcap. (Typically, it takes less than 10,000 reactor blocks to reach the 2 million softcap, depending on the length of individual reactor lines.)
It is common practice to have extra power reactors, even if it doesn't add very much on top of the softcap, in case the original efficient reactor lines are cut with battle damage. That way, if reactor lines are cut, creating shorter, less efficient lines, which inevitably drop the power generation, the extra reactors have a chance to keep the overall power generation closer to the 2 million e/s softcap.
