Same issue here. It removed 135 for me.

My admittedly massive base is just super power hungry thanks to a large amount of lasers + biter attacks. 0.15.11 pretty much broke my whole power system as my reactor setup now is just not working as built anymore (1 big reactor strip, many semi long arms with plenty of heat exchangers and turbines).

I still think that the nuclear fuel is not expensive enough though!

The only other thing that really bugs me is the higher zoom from map to world-view. I used the previous "god-mode" to place many many blueprints, some of them being just large enough for that view. But now that view is about half as much as my normal maximum zoomed out view. Still a handy feature, but for me it lost its biggest selling point in being able to view a larger area.

The only thing I found somewhat overpowered with Nuclear Power was the usage of storage tanks for accumulating steam to get around their non-stop production regardless of usage.

Yea, but that is the only sane reaction to suddently having a fuel usage that is constant instead of only when needed. If you can build a buffer into it, people will do so.

WHY ? Map view lost its advantage

I can see why they did this. If you are zoomed out fully in world view and want to view ore levels, etc, switching to map view fully zoomed in gives the same level of zoom but the advantage of viewing those stats, etc.

I had 16 central reactors (8x2) and the correct amount of heat exchangers and steam turbines running at 2.4GW before the patch (albeit with pretty long heat pipes)
Even at the most distant parts of the heat pipes the temp did not drop below 800°C

Now after the patch all of a sudden the power dropped to 800MW and the temperature of all remote heat pipes is down to 250 and lower ...

So did they tweak the heat loss over distance too?

This is exactly the same as I experience right now

This is a pretty tough change ... my factory has severe issues right now .. (defense breaking down) ...

I think it is the right call though... Nuclear power was otherwise massively overpowered.

Still broken:(

I connected a reactor and "a sink" (couple pipes, 4 heat exchangesr, 8 turbines) using one, two, or three lines of pipe, ~52 tiles long.
Result after stationary state is achieved (long time + gemespeed = ...)
pipes // T near reactor // T near sink // T diff
1 692 512 180
2 624 509 115
3 601 509 92
A savefile in the attachment.
The first and second reactor both are connected with 3 pipes, but they are build in different direction. I do not see difference, so at least symmetry is working.
Assuming small errors, the gradient for 1,2,3 pipes is like 6,4,3. It doesn't make any sense. Shouldn't it works as flow = k * temperature difference? Then, for two pipes I need put only half ot the flow into one pipe, I so need two times smaller temperature gradient. Or underlying mechanic was changed entirely?

As a "bonus" (it schows something is really wrong), try cut the pipes at both ends. We get long isolated pipes with ~500degree at one end and for example 600 at the second. And they stay in in that state! Heat isn't transported, one end is just hotter.

I'm still recommend the solution I described in posts in the 4th page of that thread. Not that complex with "implic scheme", the simple one where temperature from current tick is kept so heat flow is always calculated from temperatures from current tick, not partially updated for next one.

from that post

Code: Select all

 for (auto &v:heat_entities) 
     v.T_old = v.T;
 for (auto &v:heat_entities){ 
     double flow = 0.0;
     for (auto &w: v.neighbors )
           flow+= k ( w.T_old - v.T_old );
     v.T = v.T_old + flow;
 }

Added "create specialized sprite atlases" option to graphics settings. If checked, tile and shadow sprites won't be put into separated sprite atlases instead of the main one. This should give graphics driver more room to fit required sprites to graphics memory.

But now i can't place bigger blueprints.. I don't see location of bigger blueprints relative to other buildings

I think if DEVS increase zoom, they should add option to main menu to choose when zoom switch to map view from terrain view.

The original idea of the whole heatpipe system was to force some kind of fractal designs, which is probably not going to happen, but this should be at least closer.

malventano wrote: It's not broken, you just don't understand the new mechanic (*edit* - you missed the issue of a perfect heat balance - see below). Heat pipes appear to now have a static 1C delta from pipe to pipe.

malventano wrote:

Parallel paths assist in the heat transfer, but you have to have enough heat transfer taking place to overcome the 1C/tile thing to measure the impact properly.

malventano wrote: I'd guess you're drawing exactly 40MW from a reactor creating 40MW. It can't heat up the rest of the way.Remove a few exchangers from your build and let the reactors climb to 999C, then put them back and you'll get the same deltas but all starting at 999C, as expected.
