<queqiao-> ⟨the rocket science kid⟩ I’m thinking of using Principia in RP-1, but I’m not sure if my PC can handle it. What system resources does Principia primarily consume? I am mainly limited by GPU and sometimes CPU.
<queqiao-> ⟨test_account⟩ definitely doesn't use the GPU
<queqiao-> ⟨test_account⟩ uses CPU, but unlike the game itself, it uses all the cores, so i'm not sure it can even slow the game
<queqiao-> ⟨test_account⟩ but it does slow the game during fast timewarp and can slow down scene changes because of bigger save files
<queqiao-> ⟨test_account⟩ uses CPU, but unlike the game itself, it uses all the cores, so i'm not sure it can even slow the game without timewarp
<queqiao-> ⟨test_account⟩ but it does slow down the game during fast timewarp and can slow down scene changes because of bigger save files
<queqiao-> ⟨the rocket science kid⟩ scene changes are already quite slow for me
<queqiao-> ⟨test_account⟩ principia will make it worse, especially later in the game when there are a lot of vessels
<queqiao-> ⟨the rocket science kid⟩ loading up the game takes like 20 minutes if MM has to rebuild cache
<queqiao-> ⟨the rocket science kid⟩ I usually endure loading times by watching youtube videos during scene changes so I just get to watch more youtube and less ksp
<queqiao-> ⟨siimav⟩ ⟪test_account⟫ uses CPU, but unlike the game itself, […] ⮪ There's that though: https://github.com/mockingbirdnest/Principia/issues/3230
<queqiao-> ⟨test_account⟩ Oh, so far I haven't built a 265 part vessel 😨
<queqiao-> ⟨test_account⟩ But 100+ part vessels have slowdown, not sure if caused by principia, engines or something else
<queqiao-> ⟨siimav⟩ Or... maybe all of them?

<queqiao-> ⟨dyedquartz⟩ yeah, I've definitely noticed that my scene changes take half a minute
<queqiao-> ⟨narcik⟩ Hi, first try with principia, normally I could hit moon easily with 3150d, now cant get it under 3290 due to tangent. Any tip how to launch to hit it with max of 2060?
<queqiao-> ⟨test_account⟩ 2060??
<queqiao-> ⟨Marsh⟩ Need to launch at the correct LAN. It takes around 3150 for principia as well
<queqiao-> ⟨narcik⟩ Oh what did i wrote, mistake
<queqiao-> ⟨test_account⟩ Need to use lunar transfer planner really
<queqiao-> ⟨narcik⟩ Hi, first try with principia, normally I could hit moon easily with 3150d, now cant get it under 3290 due to tangent. Any tip how to launch to hit it with max of 3208?
<queqiao-> ⟨test_account⟩ Lan is, well, theory
<queqiao-> ⟨narcik⟩ If i use mechjeb launch to target LAN i still have to use a lot of tang to hit moon
<queqiao-> ⟨test_account⟩ So forget lan
<queqiao-> ⟨Marsh⟩ I don’t like the idea of telling people “use this mod and don’t bother understanding what it does or why”
<queqiao-> ⟨test_account⟩ It produces instant results )
<queqiao-> ⟨Marsh⟩ ⟪narcik⟫ If i use mechjeb launch to target LAN i […] ⮪ You don’t launch to target lan or plane with principia if you’re launching from the cape or similar or greater latitudes
<queqiao-> ⟨narcik⟩ tbh ive spend so much time on this shit I dont bother just braindead overcoming it at this point
<queqiao-> ⟨narcik⟩ So how can i optimise it for 3150? If i understand correctly I need to time the launch so vessel will fly perfectly into Moon after these idk 3 days or so so i dont have to change tang that much
<queqiao-> ⟨Nazfib⟩ You need to find a combination of LAN and inclination such, that the relative ascending or descending node between your parking orbit and the Moon's orbit, is at the position where the Moon will be 3 to 5 days after launch. One possible combination is "the inclination and LAN of the Moon's orbit", i.e. "Launch into plane of target". However, this inclination is not reachable from launch sites at higher latitudes (e.g. Baikonur, or...
<queqiao-> ... KSC when using Principia).
<queqiao-> There is no simple way to calculate a possible combination of LAN and inclination. Either you need to write a program to perform the calculations for you, or you use the LunarTransferPlanner mod.
<queqiao-> ⟨Nazfib⟩ +Once you are in a parking orbit with a correct inclination and LAN, the transfer burn is always approximately 3150 m/s prograde.
<queqiao-> ⟨narcik⟩ Thanks, so I just shouldnt bother with doing this manually?
<queqiao-> ⟨test_account⟩ Eyeballing is somewhat possible, but why do that
<queqiao-> ⟨narcik⟩ Well, saw few people on yt doing it so i wanted to give it a try but I quess i suck at it, thanks guys
<queqiao-> ⟨test_account⟩ There is also an option of just waiting in orbit, if the craft can last 14 days there will always be a window... Again, why
<queqiao-> ⟨narcik⟩ ⟪test_account⟫ There is also an option of just waiting […] ⮪ haha not with my early batteries
<queqiao-> ⟨Marsh⟩ ⟪narcik⟫ Thanks, so I just shouldnt bother with […] ⮪ You can _determine_ the correct LAN manually. When it comes to actually flying, no. Launch to a predetermined LAN and inclination
