Prototying Week!
v0.6.0 is out for bug testing right now (thank you to everyone who's left me a bug report so far!). I normally use the time between the public and patron release to prototype features that are either very early in development or that might not make it into the final game, but this week I have a different goal in mind.
For a few versions now a number of people, myself included, have noticed a significant slowdown in LR2 as the game progresses. My goal for this week is to track the cause of that slowdown down and eliminate it, as well as give myself some diagnostic tools for future bug hunting. I'll also be rendering out some new character positions and experimenting with some compression techniques to shrink the game file size if possible.
My current hunch for the slowdown is that somewhere along the character creation process a character is grabbing a copy of the clothing library instead of referencing the static images, and that this is resulting in a massive duplication of data every time a character is created. To test this I will be writing some debugging functions that time how long it takes to create a character, move them around, ect. Then I will see if the time scales up with the total number of people in existence, total number of people interacted with, and so on. Hopefully this will lead me to the root cause of the slowdown.

Looks like there is an error when any of the girls get to loyalty over 130. My game pops up errors when I talk to them and then auto exits the conversation. It also pops up errors when I click the detail information screen.
It's been found and fixed, v0.6.1 will be released on Wednesday and will include a couple major bug fixes.
Study up on algorithms too, they are your bestest of best friends when it comes to performance by far! :p
Just as a data point, for me the slowdown seemed to increase noticeably the more I clicked on menu items, even if I wasn't doing anything that brought in a new character (unless that is happening in a way I can't detect/control). I assumed it was something related either to the shading/textures or the action history.
I think I can agree with that assessment, I also associate the slowdowns with my activity. So, the first place to look at should be the rollback code, IMHO. I suspect it's even saved so that when you load the game, you're back in the slowdown zone.
