Short summary of your issue
Expanding all pops in Detailed List causes FPS drops

Game Version
1.0.3 (Vanilla)

What OS are you playing on?
Windows

Do you have mods enabled?
No

Have you tried verifying your game files?
Yes

How much "pain" is this causing you?
3

Please explain the issue you experienced in the most condensed way possible
In the Pops Overview panel, Detailed List tab, we can expand the Pop Groups. As more groups are expanded, the FPS keeps decreasing. In my system, expanding all pops on my example save causes >40 FPS drops (from ~60 to ~20 FPS).

Please explain how to reproduce the issue
Load the example save. Open the Population panel, Detailed List tab. Expand all pop groups. Monitor FPS.

Is there anything else you think could help us identify/replicate the issue?
I tested other expandable/collapsible lists (trades, buildings, etc) and didn't notice any significant FPS drops. The trade route list causes 10 FPS drop when fully expanded, so I suspect this is related to the number of items on a list.

I have attached a save game
Yes

Hi, Diligence,

Thanks for reporting this!

The team is constantly looking into the game's performance and improving it, especially in cases where late game saves can get demanding, and obviously what will cause issues on one device may run perfectly on another.

In this case, the issue with FPS drop may be related, like you mentioned, to the number of different Pops in the country. We received a number of other reports and feedback on the matter of Pop lists growing long towards the endgame, and it is in our database, so it's definitely something the dev team will consider when making further improvements.

Cheers!
