Lag seems to be getting worse?

[king of nowhere]

I made a big ship aptly named dream big, and it has about 1000 parts. of course it lags. but what's surprising is that, as my game progress, the lag is getting worse. even though i did get rid of some parts and reduced part counts.

as a crude estimate, i use an external chronometer to see how long it takes for 10 in-game seconds to pass while i have the big ship in physical range. a couple weeks ago, it took 31 real life seconds, so time was slowed by a third. today i made the measure again, and it took 52 real life seconds to pass 10 game seconds.

both measures were done with the game just opened after having started the pc shortly before. the lag keeps getting worse during a gaming session until i restart the pc, but even there, there is some long term lingering effect.

I noticed the same problem another time with a 500 parts ship, but i didn't think to collect hard numbers at the time

is there any reason why, as i play more on a saved game, the game gets slower? the mission is a grand tour, it's not even like i am launching additional ships for the pc to keep track of.

more important, is there any way to clear this up?

It sounds like a memory leak.

I assume if you save your game, close it and restart you are still lagging the same amount as you left? If such is the case it might be related to the more serious performance issues. (What or how to fix is is more in the realm of someone who knows how the game is saved/kept track of over time)

The other workaround might be to go and manually delete/remove the parts still in orbit, as then the game doesn't need to track them.

memory leakage is a thing, but i can fix it by restarting the pc.

this is a slower thing that happens over weeks.

Weeks of the same game file being loaded?

Or weeks of the same boot up of windows?

Or weeks of the same game running?

How many more craft do you have in game now vs a few weeks ago.  Large numbers of craft do have an impact, even when they are on rails.

same game running, if i got your meaning.

i mean, during those weeks i keep restarting the pc. but i always play the same sandbox

no other ship was launched. in fact, a few of the shuttles attached to the main ship have been retired since then (and by retired, i mean brought to kerbin and recovered)
