ccHFM VS Greater-Flavor-Mod

You can get it from here: https://github.com/moretrim/ccHFM

There's also ccHFM which I would recommend instead of the normal HFM since it does fix some leftover bugs and shortcomings of the original mod.

You can try ccHFM. "Bug fixes: the four most infamous decisions responsible for bringing down the performance of the game have been corrected" https://github.com/moretrim/ccHFM/releases If that doesn't help then basically nothing can be done. Game is very old and not optimized.

The latest version of GFM can be downloaded at: https://github.com/Historical-Expansion-Mod/Greater-Flavor-Mod

Funnily enough I had the same issue.

The Github link has a short explanation for all the submods so do read it if you're curious.

But wait, attentive readers may ask, support for Victoria II ended 7 years ago, and Victoria 3 was only released last month. What was the community doing in this time? Well, some modded the crap out of the game, adding more content than 4 years of updates and DLCs. Others stopped playing. But above all, the community amused itself by making countless memes about how awesome Victoria 3 was going to be. It got to the point where any teaser or message released by Paradox developers from 2016 onwards were being semi-ironically interpreted as Victoria 3 confirmed?!?!

gfm is tricky. It does a lot of stuff at once, and in ways paradox didn't intend it to do. You might not notice at first, but stuff is breaking in the background that will eventually corrupt your game, like what you're seeing now. In order to play it correctly, you need the correct build of the game, and the 4gb patcher exe, which you can read more about on the GitHub page.

I mean, there arent that many of them and if you download from github they and the base mod come all at once so you could just give them all a look or read the short description they all have in the github page for it if you scroll a bit down.
