I have just downloaded the latest versions and reinstalled (portable) to try to fix this without luck. Using Spring Lobby and the latest XTA game.
My system is Win7 (64), Intel I7 quad, 8Gb RAM, AMD Radeon HD 6700 Series.
My system used to let me run at 10+ speed during the early phase of the game, now I am stuck with snail speed. Yes, I did change the 'maximum game speed' in options.

Am I the only one experiencing this? Can anyone help?
Cheers, Paul.
