raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Gateaux. We currently target 1.8.1, 1.9.1, and 1.10.1. <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… | <egg> also 4e16 m * 2^-52 is uncomfortably large

<discord-> V​ee. — 😦 I installed Principia and it killed my FPS
<raptop> Yeah, a first person shooter with n-body gravity would be weird

<discord-> V​ee. — lol
<discord-> e​gg. — @Vee in what circumstances?
<discord-> e​gg. — high timewarp will slow things down (because we need to calculate more faster)
<discord-> V​ee. — I only really just tried a launch and the FPS was about half of what it usually was
<discord-> e​gg. — huh
<discord-> e​gg. — try shortening the prediction maybe?
<discord-> V​ee. — hmm will do
<discord-> e​gg. — which platform?
<discord-> V​ee. — Windows, x64
<discord-> e​gg. — hm
<discord-> V​ee. — I didn't save any logs
<discord-> V​ee. — I kinda reverted to my old GameDat and saves
<discord-> e​gg. — someone looked into a performance issue and sent us a change so I guess the next release will be a bit faster too
<discord-> V​ee. — oh cool
<discord-> e​gg. — was the low framerate in map view or when looking at the rocket
<discord-> V​ee. — when looking at the rocket if I recall
<discord-> e​gg. — huh, that’s odd.
<discord-> e​gg. — you might have been a bit short on performance margins already I guess

<discord-> S​tandecco. — @egg oh, got a PR to read?
<discord-> S​tandecco. — always nice to see that I barely understand anything
<discord-> V​ee. — I dunno, I have a pretty strong system and didn't have too many mods?
<discord-> V​ee. — (9700k and RTX 2070 super)
<discord-> S​tandecco. — are you sure it was caused by principia though?
<discord-> S​ir Mortimer. — How many vessels, asteroids and debris?
<discord-> V​ee. — Maybe like 30? This is very early campaign
<discord-> V​ee. — Removing principia bought the fps back up
<discord-> s​martdummies. — How much RAM do you have, and what other mods are you using?

<discord-> V​ee. — I have 16 gigs, and I'm using the recommended and essential mods for RO/RP-1, + I'm using SPE
<discord-> V​ee. — I think those are pretty much it? Maybe a couple more part mods
<discord-> V​ee. — I did uninstall persistent rotation, I don't think that would be the cause of the problem, I know that's incompatible
<discord-> V​ee. — I'll try a fresh install today, see how that helps

<discord-> s​martdummies. — What RSS textures are you using? You might be running into RAM limitations. Principia is a bit heavy in calculations so if you have to keep swapping memory between RAM and storage you might see a slowdown. Maybe try using some lower res textures for bodies you won't be visiting too often and see if that helps.

<discord-> s​martdummies. — That would be the 8K textures. Can't hurt to try the 4K just to see if it makes a difference. If it doesn't just go back.

<discord-> l​pg. — I am no alone!
<discord-> l​pg. — I am not alone! (edited)
<discord-> S​tonesmile. — Yep, seems to be the same issue
<discord-> F​abioKevin. — How does one launch to a synchronous orbit from a different place than the Kerbal space center?
<discord-> S​tonesmile. — You mean like geostationary (but kerbin)?
<raptop> a ~ 42,000 km (earth), or ~2,182 km (kerbin)
<discord-> F​abioKevin. — > You mean like geostationary (but kerbin)?
<discord-> F​abioKevin. — Yes
<raptop> okay, stationary, not just synchronous
<discord-> S​tonesmile. — You launch into a low orbit and raise the Ap on the an or dn, then circularize at Ap
<raptop> For a different longitude, some choice of the initial orbit parameters to get a period that will get you over the right spot before circularization *handwaves*
<raptop> Or do you mean doing a plane change?
<discord-> F​abioKevin. — For example, from here.
<discord-> S​tonesmile. — Do you want the sat over a specific spot on the ground?
<discord-> F​abioKevin. — Well, the contract wants it over this position
<discord-> S​tonesmile. — That orbit doesn't seem to have any restriction on over what ground point it's located
<discord-> F​abioKevin. — This is the contract.
<discord-> S​tonesmile. — Yeah, over any spot should be ok
<raptop> I have questions about that altitude bein synchronous. I assume that this is 2x Kerbin or something?
<discord-> S​tonesmile. — You might find this link useful, it's for RO, but the order of the maneuvers are the same; https://github.com/KSP-RO/RP-0/wiki/Getting-to-Geostationary-Orbit
<raptop> hrm, 3x?
<discord-> S​tonesmile. — JNSQ IIRC
<raptop> Anyway, highly elliptical orbit with apoapsis around (or if you're fancy above) synchronous altitude, plane change, circularize
