Alpha 7 frequent freezing

[Veneke]

Edit: Some trial and error later and I discovered the problem. Running power conduits from a geothermal to my main power network seems to be the root of it, as when I cancelled all those and went a rather different path the 'freezing' disappeared.



I'm experiencing a strange issue in Alpha 7. The game freezes for a second or less consistently every minute or so past a certain point. Perhaps pausing might be more accurate as the game doesn't lock-up or return a "Not responding" error in Task Manager when it happens. I did time it, and it seems to go through its momentary pause roughly on the half hour and again on the hour in game time.

An earlier save didn't have this pausing issue. It was only from 20 minutes before the problem manifested, so pop count etc was all the same. I played on from that save, but the problem returned almost exactly. It seems to happen during the first night of August (so 1 Aug leading into 2 Aug). I did different things, just in case somehow whatever I did caused the problem, but it reappears with remarkable consistency.

It isn't late-game lag. I have 10 people on the smallest medium map size, with few raiders so far. I loaded up a few of my Alpha 6 saves (20-30+ people, lots of stuff beyond my base etc etc) in my old installation folder and those saves don't have this issue (there is some stuttering, but only when enemies appear).

I've checked for updated drivers etc, and they're all good. I tried windowed mode, at various resolutions, and I've also forced the game to run with a dedicated graphics card. None of these have resolved the issue. Any ideas as to what the problem might be, or how it could be fixed?

Specs: Win7 (64 bit), i7-2630QM @2GHZ, 8GB ram, Nvidia 540M.

Attached is the output_log.txt if that helps.
