For me, the game gets lag spikes while I'm near my base. So my cat guy basically walks around at half speed all the time.
For reference, lag would be a delay between your commands and the actions. It sounds like you're describing a general slowdown. (also "spikes" are the opposite of "all the time")
Have you expanded your base much? Does it sprawl across many chunks of the map, or include a large number of something?
If you have been rovering around a large area, I've found that quitting and restarting can help a bit (I presume that flushes all the world chunks I'm not going to visit again.)
System stats would probably be useful to Cairn4.
I only get to day 7 because I don't have the time to walk around at half speed. It might be the dust that causes the game to slow down? That's the only idea I had, either the dust or something silly is happening in the background of the game. I'm running the game on windows 10 with a laptop (only the embedded graphics chip) so perhaps my system isn't powerful enough?
> basically walks around at half speed all the time.
I've seen this happen before, but I'm not sure exactly what's causing it yet. Save-Quit and re-loading usually clears it up, at least temporarily. It could also possibly be related to a chunk-loading/unloading issue I found recently.
Going to keep working on trying to figure it out.
