I'm not a big gamer but enjoy glest. My computer is less than a year old and runs vista. I've played simcity 4 on the system with no problem and though I know little of computer gaming I would assume if the computer can handle simcity, it should be equipped to handle playing glest. My problem is this, any time I have conflict, no matter where on the map it occurs, the whole game becomes irritatingly slow, so much so, it's nearly impossible to react to conflict, move troops to the point of conflict. I have also noticed at times, when finally defeating an enemy, the game seems to go into a super fast speed. What is causing this change in game speed because when it slows the way it does, the game becomes unenjoyable to play. I have tried the game speed controls in the game as well as downloading the game booster software with no success.
