Slow Motion Fix please

[epicentre]

Hello.

I play with a laptop too. This is what I do to run at normal speed:
- enter the game
- remove the power plug, wait 5 secs till laptop sees something has changed
- put the plug back in the socket. Laptop says he is happy to be fed again.

I can now run at full speed.

Weird, but it's simple and it works.
