I played maybe 6 games since the 1.03 patch and on the last one I was playing a 1 on 1 vs the AI with all settings standard except low resources and not too far into the game suddenly the speed went into hyperspeed. I would estimate the speed to be about 100 times normal. That was at 1X speed setting. Raising the speed to 6X just made it move at what looked like 600 times speed. Going back to 1X was still 100 times normal. Saving, exiting, and reloading still had the bug. I prefer turn-based games to RTS so I generally play at 1X speed and pause often. 100X speed is just not enjoyable or playable
I was impressed, however, that the game could actually run that fast on my system as it is a couple years old (WinXP, AMD 3GHz, 2GB RAM). I've never had any stability problems, even in beta.
Please note that I use no mods and my version is downloaded from Stardock.
