Game slows down tremendously when screen blanks (DPMS) on Linux

We are aware of them, but they have low priority. We have more important things to do. They go here in order not to take space in the main bug thread list.

Game slows down tremendously when screen blanks (DPMS) on Linux

Post by fstd »

So I noticed that my factory progresses way less than it should while I'm asleep.

It turns out that once screen blanking goes active, the UPS drop to around 1/4 of the original value -- (this can be tested with a clock connected to a programmable speaker). I'd love to debug this myself, but obviously can't for a lack of source code, so I'll leave this notice here hoping that someone figures out what's going on -- At this point I'm not even sure if it is Linux-specific or not. I am experiencing this issue on two different Computers though (one running Debian 8, the other Debian 9).

Does debian slow down the processor when screen blanking is on?
There are 10 types of people: those who get this joke and those who don't.

Hello, thanks for the report.

If it is something in the game that's causing it, it might be randomly fixed in 0.17 by rendering rewrite.
Other than that, since it can only happen when you let the game run idle, it's minor issue.

I'm not sure, but I'll investigate in this direction

Factory idle != user idle -- I can't be the only one who leaves their factory producing when asleep
