I just assumed the custom HP drivers had some customizations to the power saving settings that prevented the flickering. Turning off power saving all together works too. It wouldn't be a very good solution on a laptop but who cares about power saving on a desktop. I would rather run the latest Nvidia drivers then the older HP custom drivers.

I didn't have any luck with the HP drivers for what ever reason. I still had flickering. But if it works for others then great. I was just throwing out another option.

thanks ermax18, i just uninstalled the HP Vista driver and installed latest nvida driver 195.62, screen was flickering as expected. installed Nv GPU Pro and noticed none of the options were enabled. so decided to completely disable.  after a reboot no more flickering...

kudos to you bro! thanks for the fix.  i suspect HP have some missing registry keys that nvidia may expect...

I bet you could compare the inf file from HP's custom driver to the generic drivers from Nvidia and find the missing registry settings and then build a custom driver. Then you wouldn't even need any extra utilities to disable PowerMizer.

I see this line in HP's inf:

HKR,, PerfLevelSrc,           %REG_DWORD%, 0x3333

That is probably the magic. Nvidia sets it to 0x2222.
