What is the specs of your system and what settings did you put the sleep settings? The sleep settings can be seen when the status display is on.
The sleep setting is at 17 so cpu is cooler (temp) for a fps of 62 or so.
My system is:
Pent. 4 dual 3.2GHz
Nvidia 6600 GT
Realtek HD Audio v5.10.0.5324
Win Xp SP2
Put the sleep at 10, (default?) and it worked normal. Moved it up to
17 again and the delay returned, so maybe something to do with it.
No problem, I'll ignore the delay. No big deal.
