I just wanted to share my own feedback regarding the current state of the game. First off I will give my system specs to get it out of the way.
Windows 7 Professional 64
i7 3770k 3.5ghz (reads 3.8 off to the right for some reason)
8gb DDR3 RAM
GTX 660 2gb
Resolution 1920 x 1080
Early on I ran into no apparent issues. It actually wasn't until after turn 600 I was forced play zoomed out to avoid slow down on the map. (I enjoy playing the "long game" so to speak). By turn 1200 I was even experiencing slow downs of all kinds and battles were completely unplayable as it was taking a really long time for them to load. I threw in the towel on that one shortly after because at that point it felt unplayable as a whole. This was on an immense map with two AI And I was playing the Terrans. I should also mention it wasn't just the game that was slowing down, it was my system as well, and it continued that way after closing out the game for a few minutes.
i then tried to play the Dregin on a large map with two AI. I think I was 300+ turns in when I begin experincing trouble. Mainly in the form of the AI not finishing their turn. I'm not sure if it's because I had a lot of star bases lining the edge of my territory this time or not, but before I started that process i hadnt had an issue. I was trying to see how effective the star bases were right now. I tried reloading a previous save during the AI's unending turn but that caused the game to crash to desktop every time.
I have tried increasing my virtual memory but that hasn't helped. Windows 7 had it automatically set to 8gb and I changed it to 8gb min and 12gb Max. I've seen no improvement in that regard.
i have been enjoying the game for the most part and look forward to seeing improvements as they come down the road.
