In all FE versions up to now I had the following behavior:
After some turns the game becomes very slow, frame rate drops and all responses are delayedby like half a second.The game does no t run that smoothly on my machine, but the performance in this state is markedly worse. And this happens in every (non trivially short) session I played yet!
It happens mostly after a fight but not after every fight and sometimes also after some other actions like returning from the research screen, so I don't think this is related to the combat.
Also the HUD disappears in this state. I still get certain dialogs to show up, like , if I click on a city and press 'b' I can place buildings, but I don't see the cities info screen and build queue.
I can still keep on playing but often a crash follows after some turns. I also had a safe file corrupted when quick-saving in this state.
Does this happen to anyone else?
Here a debug file from one of my sessions: http://dl.dropbox.com/u/58333537/FallenEnchantress0_86-2012-02-25T22-24-16-859.zip
