It's worse than that. It depends on which way the whole thing is rotated: if you take a blueprint of your whole screenshot and rotate it, it will work differently in some directions than others. For example, in my screenshot below the north and west setups have items on right lane of the belt, while...

Devs, draknor is absolutely right about CRC32 not being a good choice, and it has little to do with hash output size. All of the math posted above and in the FFF is based on an incorrect assumption: that every hash value has an equal probability of being selected. This is not the case for CRC32. The...

This "fix" is really frustrating me because (a) it's just making a certain logistical challenge easier for one bug reporter, but (b) it doesn't even actually make that challenge simpler in general; it just makes one specific case simpler. The general challenge is "inserters drop what ...

To force vsync, should I switch back to opengl? Or will setting vsync=true in config.ini work even without the visible vsync option? > It happens sometimes that when you use vsync at 30hz the threads get synced in such way that it starts dropping every second game update So, no joke, as a dev myself...

Changing the opengl setting releases the game to run at 60 FPS, and the UPS along with it (after several minutes of testing). Thanks! I don't see any evidence that the game should have been running in vsync even under opengl though; config.ini and the log both had 'vsync=false' and the nvidia contro...

Hmm... I did just switch from an AMD card, although the bug repro'd on the old card as well as the new. I haven't fiddled with vsync settings, but it seems this would be a bug even if it only happens when vsync is on =)

I'll try the vsync and opengl settings tomorrow and report back.

The log indicates that vsync is disabled.

Getting the repro was a little difficult because pressing F4 seemed to temporarily suppress the effect (if you can believe it), but I've attached a screenshot with the requested info and the log from the same run.

For various reasons, I play Factorio in a 30 Hz graphics mode. Yes, on purpose. However, the game is nearly unplayable for reasons which should have nothing to do with graphics! Specifically, the game usually runs at half speed. There seems to be some kind of UPS-limiting effect which tries to cap U...
