[v18.51HF3/Steam - Ground Combat] Game freezes on start of combat at insane dificulty

[xcom]

So yesterday i tried to play on Steam choosing insane difficulty. The game takes longer to load comparing to normal difficulty ( and much much longer than the desura version). Then i start a campaign and when i went for the first ground combat, the game shows all the the soldiers in the chinook, but the cursor which shows a circle on the ground doesn't show up ( the circle where your soldier is supposed to go if you click there). Music still plays but i can't choose or move any soldier.

I tried 2 times and it frooze both times on insane difficulty. Then i tried on normal and the game ran fine.

For me it didn't crash in the steam or the dev version. Can you please make a save file before the chinook lands at the crash site, and attach it to the thread? Thanks

Ok, i checked again and it doesn't freeze, but it takes an insane amount of time for the cursor to appear, and then for the game to resolve the end-turn. Maybe is something with my computer, which is very old but still in the game minimum requisites. Core 2 duo 2.16ghz, 4 gb ram, win 7 sp1, 7200rpm hdd, geforce 570 amp.

Save file might help:

Its the steam version and fps in the beginning of combat goes to 0.01.

Try updating your graphics drivers first, you can update the by steam or manually that might solve the problem.

I'm using the second latest nvidia drivers (314) because the newest (320) have problems. Unless the game is different graphically according to game difficulty, i don't think graphics are related to this issue, because as i said it only happens on insane difficulty on steam version. Even quitting the game on insane takes much longer.

Have you tried my save ? I will try the standalone later and the desura version if i can get desura to update my game (having problems with it updating to 18.51).

[Matthew]

Yes I did tried your save and it was the same amount of time as usual. I'll keep trying with your save file.

Thanks. I just tried with the standalone version and the problem persists, so it must not be Steam; I noticed that during the "freezes" (beginning of combat and end-turn) one of my cpu cores stays between 70% and 100 % usage all of the time. It must be some calculation or memory related operation that gets out-of-hand...something that is much more complex in insane mode, like the AI.
