We currently target 1.3.1, 1.4.x, 1.5.1, and 1.6.1. <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…

00:00 <discord-> Teykn. — I remember seeing the mod name. Does it do something to orbita?

00:03 <UmbralRaptop> It implements full Newtonian gravity

00:03 <UmbralRaptop> So you actually have Lagrange points, weak stability boundary trajectories, etc.

00:04 <UmbralRaptop> Also molniya orbits

00:05 <UmbralRaptop> Also, kozai mechanism!

00:15 <discord-> 𒀯 𒄷 𒄈𒀭𒁇. — (Note: we do not know if Newtonian physics applies in Gensokyo)

12:41 <discord-> Standecco. — oh, @egg

12:41 <discord-> Standecco. — there is a problem that I've had for months

12:41 <discord-> Standecco. — for a completely unknown reason, some of my installs (they're all with principia) break and max timewarp is completely unusable

12:42 <discord-> Standecco. — like 1 second per frame

12:42 <discord-> Standecco. — in other installs, possibly with more mods, it works perfectly fine

12:43 <discord-> Butcher. — I get really bad frame rates at high warp

12:43 <discord-> Standecco. — it probably has to do with the random fuckery that happens in all installs and makes you lag; cleaning the game files (except gamedata) fixes it

12:43 <discord-> Butcher. — I just turned down max warp a bit.

12:43 <discord-> Standecco. — @Butcher principia installed?

12:43 <discord-> Butcher. — Yeah.

12:43 <discord-> Standecco. — backup your gamedata and savefile and reinstall the game

12:43 <discord-> Standecco. — then put the savefile and gamedata back

12:44 <discord-> Butcher. — Eh, it doesn't bother me that much.

12:44 <discord-> Standecco. — if you want to be even more sure it'll work ditch your gamedata and reinstall all mods at once

12:44 <discord-> Standecco. — I couldn't play, basically

12:44 <discord-> Standecco. — maybe yours is faster

12:45 <discord-> Butcher. — Seems ok at 1 million warp. Gets janky at 6 mill.

12:50 <discord-> Standecco. — 1 million warp is slow

12:52 <discord-> Butcher. — How far are you warping?

12:52 <discord-> Standecco. — 2-3 months usually

12:52 <discord-> Standecco. — not more than tha

12:52 <discord-> Standecco. — not more than that (edited)

12:53 <discord-> Butcher. — That's about 8 million seconds max, so at 1 million warp, that's 8 whole seconds!

13:37 <discord-> Kobymaru. — I can't use the two highest timewarp settings at all

13:38 <discord-> Kobymaru. — I noticed that when I started the career, I could. Now that it has more vessels, I can'

13:38 <discord-> Kobymaru. — I noticed that when I started the career, I could. Now that it has more vessels, I can't (edited)

13:38 <discord-> Kobymaru. — Its either Principia or RemoteTech. Let's see if I can timewarp in 1.6.1 where I don't have RemoteTech

13:45 <discord-> Butcher. — I don't have RT. It's still not great.

13:51 <discord-> egg. — Well yes the computational cost is proportional to the number of vessels

13:57 <discord-> Kobymaru. — hmm

13:57 <discord-> Kobymaru. — so I should clean up my space garbage, is what you're saying?

13:57 <discord-> Kobymaru. — does Principia Paralellize?

17:45 <discord-> egg. — But you only have so many cores

17:57 egg|zzz|egg has joined #principia

18:02 <discord-> Butcher. — Time for a thread ripper. 🤔

18:04 <discord-> Standecco. — @egg no, my lag doesn't care about the number of vessels in orbit

18:05 <discord-> Standecco. — it happens in a new save, in an old save, anywhere as long as it's in that install

18:05 <discord-> Standecco. — it's the install getting destroyed for no reason

18:06 <discord-> Sir Mortimer. — I really need a better computer.

18:07 <discord-> Sir Mortimer. — or maybe not. performance issues in mods are best made visible on slow systems.
