egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <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…

<Stupid Gay Furry> Is there anything I can do to mitigate poor performance with Principia besides just getting a better PC?

Reply to "Kohetro: in the main window of principia "unpinned celestials", just unclick it"

<Clayel> unpinning celestials is very good^
<queqiao-->
<Clayel> most of the lag comes from displaying the trajectories, not the calculations iirc

<Stupid Gay Furry> Sadly still doesn’t work
<queqiao-->
<Stupid Gay Furry> I think I just need a new pc unfortunately
<queqiao-->
<Stupid Gay Furry> Oh well, was bound to happen soon
<queqiao-->
<sichelgaita> What kind of hardware do you have? I don't think that Principia requires a super-duper machine, but it seems that laptops are generally problematic, probably because they insist on trading performance for efficiency (e.g., P-cores and E-cores).

<Butcher> One would usually assist off at least one of the gas giants.

<kuzinat0r> How easy it is to calculate the gravity vector using kOS? I wonder if it's worth trying to take into account the body's ablateness for landing guidance
<queqiao-->
<GoForPDI (less drag=more faster)> For getting into and out of orbit, I don’t think you need to worry about any more than straight gravity, trajectory propagation is where you need J2, J3, etc

<Butcher> Probably not. For atmospheric planets the atmosphere is a much bigger factor and for non-atmospheric you're probably better off just applying corrections en route (which will also account for engine flutuations).
<queqiao-->
<kuzinat0r> You probably right. Engine fluctuations most likely have greater effect
<queqiao-->
<Butcher> If you're doing closed loop guidance then it should be robust to oblateness and mascons.

<sichelgaita> Yeah, you're in a world of pain. "i7" can mean many things, but in general it's (1) a tiny number of P-cores (2) a fair number of E-cores mostly useless for Principia (3) aggressive downclocking.

<Stupid Gay Furry> Yeah that sadly figures

<Stupid Gay Furry> I literally cannot plot interplanetary stuff, it’s either moon or bust

<Al₂Me₆> Whenever someone says they have an 'i7' I am tempted to interject 'ok, I'll assume you have an i7-970 then'.
<queqiao-->
<siimav> It's i7 so it must be good
<queqiao-->
<Stupid Gay Furry> Nah I just didn’t remember off the top of my head
<queqiao-->
<Stupid Gay Furry> It’s an i7-13620H
