We used the 0.17.74 version and updated to 0.17.75 and since the version update we noticed that every time we go sleep and pause the game before we quit, rejoin the next day everyone get a desync error. Restarting the server fixes it. The last idle duration was ~7h, 23:35:21 last one left and 07:66:...

I know what to do, its just for debbing later.

@Twinsen thanks for the detailed information. Is it possible go do such performance breakdown on our own (your tree image), so we can better analyse our base and eliminate performance issues? If yes we also could share some data, if you want to. Because as is see the thread there are lot of views, s...

And the real problem is 0.85 and up
Large is same as small

The high peak was a save interval

1. All debug options are disabled.
2. ok
3. This issue only appears in multiplayer, singleplayer works fine everytime. Is it possible to do debugging in multiplayer, to determine where this issue came from?

Singleplayer with "game.speed = 1.0"

Here are some testings i did with nvidia linux graphic debugger to track the fps: 1. pic is small resolution (645x382) 2. pic is large resolution (1855x1056) game.speed = 0.7 https://i.imgur.com/wBYYlzd.png https://i.imgur.com/CgHyTFe.png game.speed = 0.75 https://i.imgur.com/hMJSHvQ.png https://i.i...

Ok to reproduce try to join our server: fankserver.com
And tell me your UPS/FPS, because its only affected in multiplayer

Singleplayer:
avg 49 min 40 max 55


Both values are always the same.

Multiplayer:
With "game.speed = 0.8"



UPS is always high, only fps drops extemly.

I'm and some friends are unable to join, or join very slow. I can't speak for my friends, don't know what OS or hardware they have. For me: http://i.imgur.com/dnxJamY.png What happens if i join on "catching up", while bar moves backward: http://i.imgur.com/XBuljW6.png I opened it so they d...

@HanziQ i still see the issues, but could it be that these issues are there, because they were placed before the patch?

After some time, some train signal switches to red and won't change back. But the way is free and not blocked by something. Removing and placing it again will fix it. It's marked with a large "Why is this train not moving" marker. https://steamuserimages-a.akamaihd.net/ugc/7716508121639689...

During the desync i tried to build a train rail from a blueprint.
The "auto report for desync" window does not appear.

I'm running Ubuntu 17.04

Ah nvm it looks like he has ISP issues.

I've tried the fast fix "/c game.forces["enemy"].kill_all_units()" and my fps issues are done and the catching up issue is much faster than before, thanks for that. A temp solution for faster catching up is pausing the game :D But we still have some clients (with a good hardware)...

Maybe not related but here a debug screenshot of my fps issues.

Before the update we had a catch up time about 5-10 sec. after the update the catch up time is about 1-5min. And the catch up "bar" moves back and forward. e.g. 50% -> 60% -> 55% -> 65% -> 70% -> 65% -> 60% ... The CRC failures like if you watch e.g. belts, you will noticed they will stop ...

After updating to 0.15.6 -> 0.15.9 we noticed long "catching up" and it looks like there are some CRC failures ("mini"-freezes with recover), but no desyncs. Logs does not show something usefull. 0.000 2017-05-07 17:54:54; Factorio 0.15.9 (build 29504, linux64, headless) 0.000 Op...
