⟨Castor joufflu⟩ I have a question , who do you add principia to the rp1 express install from ckan, because when I download the principia mod on the GitHub and add it to the file of my 1.12.3(the latest version supported for principia) rp1 install, I get some weird minors bug and the orbit of every planet is bug, like every planet is on a different vertical axe’s(the solar systems is like a burger). So is there a specific way of installing...
<queqiao->
... it or a config that I don’t know, or is this a version conflict , and how can I fix it. Thanks in advance for the help
<queqiao->
⟨Cirelion⟩ Principia isn't on CKAN, the way you installed it is correct
<queqiao->
⟨Cirelion⟩ You're most likely getting confused by the reference frames
<queqiao->
⟨Castor joufflu⟩ Okay
<queqiao->
⟨Quattro rumbass⟩ I’ve a question as well, how much ram should I have to play with principia
<queqiao->
⟨Castor joufflu⟩ ⟪Cirelion⟫ You're most likely getting confused by […] ⮪ Is there a way to have the normal sun reference frame in the tracking station ?
<queqiao->
⟨Cirelion⟩ Read the link I send
<queqiao->
⟨Cirelion⟩ ⟪Quattro rumbass⟫ I’ve a question as well, how much ram […] ⮪ I ran it fine on 16GB, but I'm not sure if less is also good
<queqiao->
⟨Castor joufflu⟩ ⟪Cirelion⟫ Read the link I send ⮪ Thanks a lot
<queqiao->
⟨Quattro rumbass⟩ ⟪Cirelion⟫ I ran it fine on 16GB, but I'm not sure […] ⮪ can I ask what cpu you have?
<queqiao->
⟨Cirelion⟩ 6700k
<queqiao->
⟨Damien2⟩ Castor joufflu the default reference frame is one where the surface of the earth is fixed. In that reference frame (just like when you look up in real life) the sun and everything else spins around you. That's why it's all circles
<queqiao->
⟨Damien2⟩ it's down to you to choose which reference frame you want to be in at any particular moment
<queqiao->
⟨Damien2⟩ when viewing the sun and the planets around it, you'd use one where the sun is fixed
<queqiao->
⟨Castor joufflu⟩ Okay
<queqiao->
⟨Castor joufflu⟩ Thanks for the help
<queqiao->
⟨Quattro rumbass⟩ So I don’t need an insane CPU to run principia just more ram
<queqiao->
⟨Quattro rumbass⟩ +🐏
<queqiao->
⟨Damien2⟩ ⟪Quattro rumbass⟫ So I don’t need an insane CPU to run […] ⮪ CPU is important. more so than RAM imo
<queqiao->
⟨Damien2⟩ but the CPU load is dependent on the amount of work you want principia to do
<queqiao->
⟨Damien2⟩ planning long trajectories at high accuracy is costly
<queqiao->
⟨Quattro rumbass⟩ I’ve already got a decent one and I only got 8 gb ram
<queqiao->
⟨Damien2⟩ but you don't really need high accuracy when planning interplanetary routes
<queqiao->
⟨test_account⟩ ⟪Damien2⟫ CPU is important. more so than RAM imo ⮪ CPU is important but principia is using CPU cores that are mostly untouched by the rest of the game
<queqiao->
⟨Damien2⟩ just don't plot a long trajectory when orbiting a planet. that's what makes your game crawl
<queqiao->
⟨Damien2⟩ even on a beast PC
<queqiao->
⟨Damien2⟩ you'll get a feel for how it all works
<queqiao->
⟨Quattro rumbass⟩ What’s considered a long trajectory
<queqiao->
⟨test_account⟩ in LEO? 1 day
<queqiao->
⟨test_account⟩ interplanetary? 1000+ days
<queqiao->
⟨Quattro rumbass⟩ I’m trying to run more than 60 days interplanetary
<queqiao->
⟨Quattro rumbass⟩ my game just starts dying
<queqiao->
⟨Damien2⟩ ⟪Quattro rumbass⟫ What’s considered a long trajectory ⮪ it depends. plotting a thousand revolutions around earth at 1cm accuracy is going to make your PC lag. 100 years around the sun? not so much
<queqiao->
⟨Damien2⟩ * sun at 1km accuracy?
<queqiao->
⟨test_account⟩ ⟪Quattro rumbass⟫ my game just starts dying ⮪ RAM issue
<queqiao->
⟨Cirelion⟩ ⟪Quattro rumbass⟫ I’ve already got a decent one and I […] ⮪ Honestly, ram is super cheap, You can get another stick of 8 for about 20 bucks
<queqiao->
⟨Quattro rumbass⟩ I tried to plot a trajectory to Venus
<queqiao->
⟨Quattro rumbass⟩ It only got better at 10km tolerance e
<queqiao->
⟨Quattro rumbass⟩ ⟪Cirelion⟫ Honestly, ram is super cheap, You can […] ⮪ I’m upgrading to 32, I was going to anyway this was just the nail in the coffin

⟨Clayel⟩ ⟪Cirelion⟫ Honestly, ram is super cheap, You can […] ⮪ i upgraded to 64 gigabytes of ram and ksp hasnt crashed in months
<queqiao->
⟨Clayel⟩ even with heavily modded installs
<queqiao->
⟨Clayel⟩ its amazing
<queqiao->
⟨Clayel⟩ the vast majority of (my crashes atleast) were from ksp trying to use more ram than i had
<queqiao->
⟨Cirelion⟩ Aye, I had the same experience after upgrading to 48
<queqiao->
⟨Clayel⟩ ive had ksp use 32 gigabytes of ram at times
<queqiao->
⟨Clayel⟩ no clue about principia tho
<queqiao->
⟨Clayel⟩ im just hoppin in here
<queqiao->
⟨Quattro rumbass⟩ ⟪Clayel⟫ ive had ksp use 32 gigabytes of ram at […] ⮪ How? The most ram ksp used for me was 6 and I only have 8
<queqiao->
⟨Clayel⟩ ⟪Quattro rumbass⟫ How? The most ram ksp used for me was 6 […] ⮪ weird, ksp's using 18 gigabytes for me right now
<queqiao->
⟨Quattro rumbass⟩ what the hell
<queqiao->
⟨Clayel⟩ it might decrease ram usage based on how much you have
<queqiao->
⟨Quattro rumbass⟩ True
<queqiao->
⟨Clayel⟩ like i used to have 16 and it used to run with about 14 gigs
<queqiao->
⟨Clayel⟩ but occasionally it would spike over 16 and crash
<queqiao->
⟨Clayel⟩ now it never crashes
<queqiao->
⟨Clayel⟩ does it crash often for you
<queqiao->
⟨Quattro rumbass⟩ not really
<queqiao->
⟨Quattro rumbass⟩ Only if I really push it with principia (which is why I’m upgrading to 32) and try going beyond 1000 days flight plan with 1cm tolerance
<queqiao->
⟨Quattro rumbass⟩ although I did have 1 fps
<queqiao->
⟨Clayel⟩ here we go i found the picture of it using 32 gigs
<queqiao->
⟨Quattro rumbass⟩ Sadly I can’t upgrade to 64 ram
<queqiao->
⟨Quattro rumbass⟩ would it could
<queqiao->
⟨Quattro rumbass⟩ * if
<queqiao->
⟨Quattro rumbass⟩ ⟪Clayel⟫ here we go i found the picture of it […] ⮪ holy u got 38 tabs of chrome open? truly a monstrous pc
<queqiao->
⟨Clayel⟩ indeede
<queqiao->
⟨Clayel⟩ * indeed
<queqiao->
⟨Clayel⟩ its really just ok, ive just got 64 gigs of ram
<queqiao->
⟨Clayel⟩ ⟪Quattro rumbass⟫ Sadly I can’t upgrade to 64 ram ⮪ you dont have 2 ram slots?
<queqiao->
⟨Clayel⟩ its really just ok, ive just got 64 gigs of ram which makes it op there
<queqiao->
⟨Quattro rumbass⟩ I do
<queqiao->
⟨Quattro rumbass⟩ It’s a laptop
<queqiao->
⟨Clayel⟩ mine is too
<queqiao->
⟨Clayel⟩ here lets move to #offtopic💤 so mods dont get mad
<queqiao->
⟨sichelgaita⟩ ⟪Quattro rumbass⟫ Only if I really push it with principia […] ⮪ I'd be curious to hear why you think that you need 1 cm tolerance for flight planning. Principia barely gives you that kind of accuracy on the position of celestials. You might need that accuracy during a rendezvous, but there is no way that you'll be able to execute a 3-year flight plan to within 1 cm.
<queqiao->
If you ask for 1 cm we'll give it to you, but you'll use ridiculous amounts of memory for no good reason.
<paculino>
Realistically, with rendezvous that much tolerance won't help much, since the target is much larger, even if targetting the docking port itself. Right?
<queqiao->
⟨test_account⟩ There doesnt seem to be any use case for 1cm precision 🤔
<queqiao->
⟨test_account⟩ In fact the default 1m is to much
<queqiao->
⟨test_account⟩ * too
<queqiao->
⟨test_account⟩ Setting the default to 10m would greatly benefit the performance for users who just leave the default settings
<queqiao->
⟨Quattro rumbass⟩ ⟪sichelgaita⟫ I'd be curious to hear why you think […] ⮪ I meant 1m
