"We will fix the slow performance issues in the next update" - Paradox Interactive, 2019 or something.

The "performance fixes" is going to be PDX's Mojang's "Removed Herobrine".

I really want an update before EU5 where the issues are thwarted and makes the game run easier on any console, any system, any country. I wish the game would run well like in Ludi's videos.

Hardware doesn’t really matter. My intel cpu has 5.2gHz but can not handle speed 5 in 1444. According CPU Thread is at 100% all the time. It becomes more slowly over time up to a point where speed 5 does not differ to speed4. Usually after league war.
It runs almost smooth at speed 4, in 1444. Though it spikes to 100% at monthly tick.
Also I noticed lag during the month(6th-10th day at speed5) since a few patches.
Problem is the algorithmic complexity. I assume there are too many quadratic ( or worse) growths.

I think the slow performance is from the weight of troop numbers and buildings and development (probably). To combat this, there should be settings that decrease force limit for bad computers and disables going over the limit.

Yes, very slow. Just test it against an earlier patch and you will see how slow it has become.

Did you make their provinces uncolonized or did you give the provinces to you? One country owning a lot of provinces could slow down the game in other ways. For example the notification to create new states caused a lot of lag if you had many provinces in some patches last year.
Yep as it checked everyday if over gov capacity or not

Provs do not generate significant lag in vanilla. Tags do. The game runs very smoothly when AI is disabled.

I mean it is just common sense. Vanilla provs contain a few values in them, like Base Development, History log, buildings. They never do anything by themselves dynamically, other than change a few values like tax income, autonomy, etc. every month. You have to go somewhat over 5000~6000 provinces before the game starts having performance issues. Currently there are 4941 provinces, including IDs for Lakes (which have even less data), Wastelands (which have even less less data and has a near-0 effect AI calculations at all), and IDs for Random New World, which don't even exist on the map most of the time.

A single tag performs weighted calculations and dice rolls every single day to make its decisions. They add even more dice rolls for country event, chance for rulers to die, and more.
The problem is pathfinding.

I'm going to join the club here and say that performance has really taken a hit. Especially compared to patches like 1.30.6 and pre 1.30 such as 1.25 or 1.29. I recently upgraded my hardware and it's safe to say that hardware has a very negligible impact on performance. I went back to 1.29 and the performance is absolutely night and day.

Interesting because when I upgraded my performance increased massively. Might just be the fact that my PC was very old.

Maybe tags lower performance more, but having to many provinces cause lag too.

From creator of EU4, Johan. Source: https://forum.paradoxplaza.com/forum/threads/eu4-no-mapchanges-and-whys.1490842/

"Performance . Each province that is added, adds several NxN factors to a lot of calculations, and after 8 years of optimization of the game, there is simply no way to add more provinces without permanently hurting performance. Leviathan already took us past the point of no return when it comes to performance. In hindsight, we should have kept as maximum province count at <3000, and made it more even around the world, and kept adjusting borders of them".

This would make lots of people with pet countries/regions mad but I would really like if they refactored the map globally to reduce the province count overall, and to spread the province density a bit more uniformly. I think adding provinces gives diminishing returns on enjoyment added, while hurting performance.

I doubt this is gonna happen though.

and the team that made the buggy 1.30, 1.31, 1.32, and 1.33 patches suddenly knows all the issues?

There are mods on workshop addicted to adding provinces. You have to reach the 5000 range before game performance is severely gimped because of new provinces.

Actually the main offender of lag is probably something internal. I've seen several people have problems running nearly identical mod versions on 1.32 vs 1.30. Many modders have quit modding because of bad, unoptimized patches since 1.31+. Its very sad.
