Hi,



My girlfriend and I have been playing a coop game on Endless vs AI. At this point in the game (turn 150), the game is borderline unplayable due to the long end turn times. This has been steadily getting worse the further into the game we get. I think for the past 20 turns it has been getting progressively worse.



I have attached a save game to reproduce the issue:



1. Load the save game (you should load as Pink - Ardent Mages)

2. Invite player 2 to play the game (have them load as Cyan - Ardent Mages).

3. Start the game.

4. Once loaded, note that player 2 will be virtually unplayable for the first 5-10 minutes of each turn waiting for AI moves to process.

5. Player 2 ends turn.

6. Player 1 ends turn.

7. Wait for 15+ minutes before the turn is finished computing.

8. The previous turn seemed to take ~10min to compute and the turn before that was perhaps around 5min.



In case it matters:



Player 1 is playing on a high end machine:



Intel Core i7-4770

16GB RAM

GTX 770



Player 2 is playing on a Surface Pro 2.



We have completed many other games on this setup prior to this game, however all of them were on Impossible or lower difficulties. It seems the Economic boosts of Endless difficulty permit so much more units to flood the map and cause performance issues. That's my guess though, but it definitely seems limited to the Endless game mode.



Another note is that I don't believe the end turns became prohibitive until we declared war on both remaining AI empires. So perhaps it is the AI processing its unit strategies. Dark blue has a very large number of armies. Both Cyan and Pink have a large number of armies as well.



Hope this can be addressed otherwise we would have to ensure we end any Endless game prior to turn 125-150.
