Since one of the last updates I get huge UPS drops whenever I build roboports manually.
I verified on some of my older maps/saves and it's not depending on the map.
Just load a save big enough to have UPS a bit below 60 and try to build/place roboports by hand, you can watch the UPS going down immediately.
It doesn't matter where you do it, inside a base, far away from anything, always the same.
If you place a blueprint with only one roboport in it, it doesn't show this problem.

Why was my post moved from bugs to technical help?

Does a UPS drop from 50 to 15 for just holding a roboport in hand not quallify as a bug?

Can you post screenshots with the debug option show-time-usage (see 68653) enabled both when the issue is not occurring and when it is? A log file might also be useful.

Sure, here it comes.

Looks like you also found 122121, which looks similar but I don't think is related. Most of your time is spent in gui-render-preparation (45ms, which is... a lot). A screenshot of the issue with show-gpu-time-usage may or may not be useful. A save also may or may not be useful.

Addendum: I've seen much smaller performance issues left in bug reports, not entirely sure why this was moved to technical help. (Nor can I tell if it was done so by a mod or dev.)

I agree. Moving back to bug reports. I believe it is related to fix for 117994

Thank you for the log. Can you also upload your save, please?

Unfortunately I get a http-error when I try to upload the 79MB file.

But as I wrote in first comment, the bug is not map-related, I tried several old maps and the roboport shows the same behaviour.

See 3638 for how to provide the save.

Somehow I overlooked the gpu-time request you made

Thanks, using your save we are able to see similar slow down as you do. Genhis is looking into it.

Thanks for the report, this is fixed for the next release. I forgot to divide radius by 32, so the radar minimap visualization logic traversed a lot more chunks than necessary.
