The problem is as follows.
The game starts. The map starts. OK, good so far. But every time about 2 minutes after the battle has started, the PC freezes. It freezes much quicker in space battles and a bit slower in land battles, but I cannot finish any game. An interesting thing is that I tested a normal skirmish game and I lowered the number of units (bots) per team and sometimes it did not crash. But when there are more units, it crashes quickly. I pass the system requirements and I don't know why the game doesn't work.
