My save is much larger, UPS is down. Checking breakdown, I see that particle update is always 1 or more. Is there any good way to reduce particle update?

I assume that's a drawing system process, but what the heck are they calculating?
Note that range of artillery is long enough, so there should be no active enemies.

You'd better off disabling space effects, they tank fps a lot.

I remember there was a version of the game that was causing high usage of ressources like you show. It was a "bug" and was corrected though, but it had the effect of increaseing time required for particule calculation and it turned out the biggest responsible were the number of demolisher in Vulcanus.

I don't know if that is still the case today that demolisher ( in large numbers) could cause this. I know it was fixed for the scale at which i"m playing but when i see "particule update" again, i'm always thinking demolishers.

I don't recall that impacting particle time, but that was 120275, which was fixed in 2.0.33. (Granted, that's still experimental, so it may help a bit in this case if he's not on that channel.)

I can't find where i reported it but it was another thing, what you link seem more recent. Although when reading the later post that even without demolisher the particles are still representing roughly the same amount of time, i suppose it would be those in space.

Interesting report, I used the command to annihilate enemies in Vulcanus and there was no change in UPS. If the update does not improve this, I will raise another bug report.

That did reduce the time spent on demolishers (SegmentedUnit) by about 0.85ms/tick, but it doesn't look like they were a huge problem for you.
