I've been taking a break for a while and just got back for the new update, but my old factory is running very poorly at 14-16fps with the F5 overlay

I've been out of the game for along time now, but i'm pretty sure it used to run at ~35 fps before 0.11, so maybe it's time for some optimization?

Keep in mind it's a big, old save 160 hours in.

I've noticed this as well. My ~120 hour factory used to give me in the low 20s fps with 0.10.12, with 0.11.1 it's rarely above 10. UPS is sitting around 25, if that information is at all relevant.

I too was thinking this update would bring a performance upgrade, due to the announced belt optimizations. I was hoping to be able to play with Belt World again.

That save was running at 25-30 FPS with 0.10.12, but in 0.11.1, it runs at 12 FPS/38 UPS.

I have a newer save game (much lighter) that ran constantly at 60 FPS in 0.10.12 and now runs between 56-57 FPS/UPS.

I didn't really have the time to do the optimisations, the bugfixing and multiplayer and other stuff didn't give me much spare time to do that, but the optimisations will come for sure.\

The thing with fps is not really a bug a but new kind of behavior. The game tries to have the UPS closer to 60, mainly to not slow down other people in multiplayer, but also because it tries to not slow down. Once we optimise the game again, it should be faster for you as well.
