Slow-motion in games after restoring from S3 resume

[asdasd123123]

I'm having a very strange bug, I didn't realise it but today when a friend of mine came over to play some Flat Out 2 at my house, he said the game was running waaay too slow.
And not laggy, I get the fps, but the time scale appears to be at about 0.5x real time.
I did a warm reboot and what do you know, it runs so damn fast I can't drive the car any more

I'm using full suspend to ram (S3)
And when checking it out, it's actually prevalent in many games, some just down right lag, others do slo-mo, especially car games, but it might just be more noticeable there.

Is it fixable?

I'm very fond of putting it in standby, boots in 1 sec is about right
Having uptimes of sometimes several weeks with no errors, just games running slowly, apparently :S

I've run several BIOSes, having the same speed ingame, and I'm running the very latest BIOS atm.

Well, I figured the problem out my self...
I added this in boot.ini after my OS line "/usepmtimer"
And voila, no more turning off one core to play games, and no more slow motion.
