From me: Unfortunately, I think there might be some kind of memory leak in 1.05 test as my game seemed to become lethargic after about 3 hours of continuous playing. This was not the same issue I had before. Everything slowed down. Even bringing up the menus was slow. Probably not a show stopper, but something to look at.
From smjjames: "Hm, I'm seeing something similar. This morning, the game seemed a bunch faster last night after I had played for a long while, particularily during proccessing the next turn and the autosave takes a while and the lag is noticeable when I complete a research and select a new one, the window comes up during the autosave phase and I had significant lag last night where it would take a while to close after clicking done, while there was no noticeable lag. Even saved when a research was about to complete, shut down computer to clear cache and whatever to be sure, and it was definetly faster. I'll try to observe when it starts getting slow.
Should create a new thread for this though."
I don't have a save game for this, but it probably wouldn't be useful as a loaded save is fast to start with. What I can tell you is that I was playing with a fairly large galaxy, but with lots of smaller sectors, so there were a lot of "nodes". That may or may not be important. If you really need a save the one I provided for the ship shuffling problem is basically what I was playing when this slow down began to be noticeable. I was just continuing that game in test 1.05 and in a few hours EVERYTHING began to get slower and slower. Quitting the game and reloading the last autosave brought it right back to "normal" speed.
