Game running significantly slower

The preview builds (e.g. the Ranching preview) run with extra debugging turned on to make crash reports more useful during this period. Unfortunately this has a significant impact on performance, so for the duration of the preview it's going to run this way. When the Ranching Upgrade goes live next week, we turn off the extra debugging and the game will go back to running normally. After that if it's still running slow, please let us know right away!

And thanks for this report this in any case, we're glad you took the time.

Honestly, thats great news and I'm glad to hear.  I wondered if it might be something like that, but I did want to mention it in case it was unintentional ya know.  Thank you very much for taking the time to reply to me and I'm looking forward to the actual release!  

This slow down is far more significant than all other previews.  I've played them all and this is the first time I've had stop because it's unplayable.  At cycle 150.

saving and reloading seems to help for awhile.........

Cycle ~350, 14 Dupes => Savegame loading => 12 FPS

After 1 Hour => 7 FPS. Yay.

When the game saves, I have 1 FPS I think, i need a break till the release. Not funny at the moment.

I just picked up the game again last night after 6+ months. It's ridiculously slow. I get 12-24 fps, with dips below 1 fps at moments (especially the start of a day -- which, after reading this thread, sounds like is due to autosave). All this while Task Manager says it's using 8% of CPU and the rest of the system is mostly idle.

After day 20ish it went up to ~40fps, but still varies up and down enough to cause noticeably jerky animations.

I'm using Steam, mainline release ("Betas" says "NONE - Opt out of all beta programs"), Windows 10 PC with 64G RAM, an i7 CPU @4GHz. I have an NVIDIA GeForce GTX 980 Ti with G-SYNC enabled. 

...and by day 100 it's down even further, to 10-16 fps most of the time, on all speeds. With frequent jerkiness and occastional de-bursts down to the single digits.

 

New info: I just disabled all the useless (to me) streaming/capturing services that NVIDIA installed and set to run on startup as part of GeForce Experience. I also moved my game installation from my HDD to my SSD, and set it to full-screen instead of fullscreen-windowed. It's running much more smoothly now... not sure if I can say it's solved yet.
