⟨patrikcath⟩ this is just a picture of grass and an inconspicuous pile of leaves???

⟨protongamin⟩ ⟪patrikcath⟫ this is just a picture of grass and an […] ⮪ yeah lmao, no context behind it its just a pile of leaves
<queqiao->
⟨protongamin⟩ I don't see no cat

I am not responsible if any of you get predated

⟨blackeagle_612⟩ Is it normal behaviour that Principia is like a 1 frame per 5s diashow on a 5600X with 32GB RAM? I am trying to plot my first interplanetary manouver to venus and its just not possible with that performance. Am i doing something badly wrong?
<queqiao->
⟨blackeagle_612⟩ +plotting in mapmode
<queqiao->
⟨nazfib⟩ No, not unless you crank up the number of steps too high for your PC to handle.
<queqiao->
⟨nazfib⟩ * that performance is not normal,
<queqiao->
⟨test_account9540⟩ Default steps setting is 1024 and tolerance 1m, both settings are not good and need to be changed
<queqiao->
⟨test_account9540⟩ I use 16384 steps and 10m tolerance for short interplanetary trips, works ok for me but might vary from PC to PC
<queqiao->
⟨test_account9540⟩ Also make sure you set history to 0 or some small value, and didn't increase prediction settings to some high values in the main principia window (these affect the magenta line)
<queqiao->
⟨blackeagle_612⟩ What does the prediction effect? Just how far to the future every body in the RSS is calculated or anything else?
<queqiao->
Ah well. Works a little better with your settings. I tought i need to crank the steps up higher since otherwise there was the "Integrator reached maximum steps after X days" showing.
<queqiao->
⟨nazfib⟩ The prediction changes how far ahead the magenta line is calculated
<queqiao->
⟨test_account9540⟩ ⟪blackeagle_612⟫ What does the prediction effect? Just […] ⮪ The steps setting is a compromise between getting "maximum steps" message all the time and slowing your PC to a crawl
<queqiao->
⟨test_account9540⟩ The message goes away after some fiddling with the plan, like changing the maneuver time with the slider
<queqiao->
⟨test_account9540⟩ If it doesn't go away then you really need to increase the steps setting
<queqiao->
⟨test_account9540⟩ The steps setting is a tradeoff between getting "maximum steps" message all the time and slowing your PC to a crawl
<queqiao->
⟨blackeagle_612⟩ Thanks. Was just curious. Because neither RAM nor CPU were even close to half usage and the frames kept being awfully low anyway. So i thought i must be doing something wrong.
<queqiao->
⟨blothorn⟩ Note also that it’s dramatically harder to calculate a year of LEO than a year of interplanetary transfer; I’ve found it’s generally best to plan your TPI burn and then turn up max steps.

[Principia] Starcatcher2009 opened issue #3744: Principia can't generate gravity models when stock planets are scaled with Sigma Dimension (REPOSTED, JUST HEAR ME OUT) - https://github.com/mockingbirdnest/Principia/issues/3744

⟨egg⟩ StarcatcherKSP, GitHub issues are not a chat app, they are a way to track the work we are doing. Under no circumstances is it ever appropriate to knowingly file duplicate issues. In addition, you have already discussed this matter here. There was no use to filing the first issue to start with; since you clearly fail to understand the documentation we provide, you could ask for clarifications here instead, where you might get them from...
<queqiao->
... others instead of wasting our time.
<queqiao->
I will not tolerate more of this utter disrespect for our very scarce time.
