graphics performance drop after wake up

[rickette]

Hi,

I've installed a fresh 10.7.4 computer with my old working build.
I figured i'll get sleep working this time, i didn't bothered to get that till now.

So it works well, i can sleep and wake up without loosing anything : usb, keyboard, wifi, ehternet, etc...

However, every time i wake up i see a huge performance drop in 3D games. So huge that any game is not playable at all.
If i reboot everything works fine again.

I really don't know how i can manage that. Any help appreciated...
My build is in my sig.

thanks

Sorry for the late reply.

I changed the smbios to 12,2 and it works indeed.

Thank you for the help !
