Major lag on many moves (Endless Legend)

Hello! Please pay attention to this topic because the problem I describe occurs in many players. Actually, she is unpleasant lag on a large number of moves, plus is likely not to load your save, or rather following a pass in the game will last forever with all this action will be accompanied by sign on a red background that says "a serious error has occurred". The first time the game launched since the release of the first working Assembly, appearing on the torrent in order to get acquainted with the gameplay. The game is wonderful, like, played Endless Space before that, however to finish at least one script to the end I have failed, only once, only when it is not spent the large amount of moves. So, a year and a half I decided to go back to this game — installed "Repack" from the mechanics with all the DLC in the hope that they solved those problems since the release. To run the script on the biggest map with 8 different players as before. Somewhere in the course of 50+ at the next boot popped up an old, familiar message "serious error." The subsequent increase in the number of moves in the game were observed with apparent subsidence FPS, lags or freezes can't quite describe, especially the action after the change of speed, change of winter/summer. Play is in principle possible, but sometimes it becomes frustrating to look with the eyes, tired look. I guess when my script reaches the status of 200+ moves and I got all the chances not to be able to continue the game due to the inability to pass the course, as it happened in my game a year and a half ago. Incidentally, even in this limit 50-100 moves me at the moment this problem once appeared, had to dance with a tambourine, to run an old save luckily managed to regain progress. Owners of licensed copies purchased on Steam, have You encountered this problem? As for me version torrent edition bought in this regard is no different, it is a pity that the game is still no need of optimization and solution of some technical problems. Or am I wrong? Share your experience and reasoning, it may still have this problem. My computer configuration is not that weak: Nvidia Geforce GTX 760 (asus); i5-3570k; 16 RAM; operating system 7 64-bit. I can't pull the game on the biggest map with as many players? Playing against the AI. The image error will leave below, please write Your opinions about this and possible solutions to this problem. I would not want to leave this game due to technical nesurazits.... Thank you for your attention.
