I have noticed that the games responsivenes degrades over time, the longer a game goes.
In particular this is noticeable in factory queues. After a while, build orders cannot be removed from the queue at all (by right-click or shift-right-click)! Note that at the beginning of the game it works just fine and after a while, it takes multiple clicks until at some point, it just stops working alltogether. Same goes for drag & drop within a factory queue. Fully stopping the production still works but has some noticeable delay.

Less noticabe but still degrading is the responsivenes of move orders for units or ACU, so that orders are sometimes not being followed and need to be issued multiple times.

Sorry @Jip, this took a while but I have an update on the isse (game log and video link attached). Note that this time I did not use any (Ui) mods whatsoever:

• The factory queue stops being responsive if there is a longer period of no factory queue updates, i.e. no units roll off or no unit is added to the queue

• This apparently is not tied to a specific factory but rather to any factory in the game

• The issue is easiest to reproduce if you stall mass, i.e. units roll off very slowly and factory queues are therefore not updated and no units are added to any factory by the player.

• Therefore, this issue should be reproduceable already in early game, which I managed to do after about 8 minutes in a separate game (not in video). Just build a bunch of factories, que in a bunch of different units, stall really hard and try to drag & drop or right click in any factory queue. If queue is not responsive, either add a new unit to a queue or wait for a unit to roll off the factory. This should allow drag & drop / right-clicking again.

• My best guess is that it has to do with how factory queues are handled / polled / updated within the game mechanics

Thank you all for your help, @magge, @deletethis, @Sprouto, @Zokora and @arma473. I will play around once more with my sound settings, config, etc.. Should anything useful appear, I will let you know.

Cheers

Update: The behaviour is actually more bizarre than I expected. I just recorded a game vs AI. A short summary of the key findings:

1. Queue is somtimes unresponsive, even re-selecting factory won't help
2. The behaviour, as said before, is more severe after some time in the game
3. After trying to manipulate an unresponsive queue, somtimes the queue seems to be duplicated / copied multiple times
4. When being copied, not the whole queue is copied, just parts of it
5. Unresponsiveness of the queue appears to be related with units being produced. Somtimes, after a runit rolls off, I can remove or drag & drop items from the queue
6. Drag & drop often works once or twice and then stops working. If so, right-clicking also stops working

..sorry for the crappy microphone!

By looking at the behaviour of the queue being duplicated: It appears as if this might be a result of all the failed attempts of right-clicking being somehow added to the queue?!

@jip Alright, will try without any mods! The only one I have active is advanced target priorities.

You are welcome, thanks for investigating!

I gave it a testrun on FAF Develop and everything seems fine! Thanks a lot for investigating, @Jip !

As far as I can tell so far:

• drag & drop is working
• modifying unit counts within a queue is working
• there is no more random adding of units to the end of the queue after drag & drop

This will be a huge gameplay improvement, at least for me, since I am using factory queue adjustments a lot.
