NP8662 performs horribly with newest drivers

It seems that everytime I install a new graphics/audio driver, the laptop gets slower. It had the infamous crackling problem from the beginning, but now fps is just pathetic in almost any game. I have nvidia 195.62 and realtek hd 2.40R, which to my knowledge are up-to-date. Which older versions are the most stable and where can I download them?

 

best drivers ive used so far are 186.81 and im not updating cos im happy with them.

For Windows Vista & Windows 7

The links are broken.

 

ive just fixed them as you was looking at post. try again

 

Thank you. I will comment on the performance after installation.

 

Yep, 186.81 are the best ATM.

 

It does seem to be better now. But the crackling, which the latest version alleviated, got worse again. Oh well.

 

damn crackling... cant wait till a real fix comes out for this! I disabled powermizer but my GPU temps are idling at 50 instead of 38 which demands more on my fan, not good

and even with powermizer disabled i can still hear a bit of audio crackling now and then. they really need to get their act together and come out with better drivers

 

wouldnt that be the realtek on board sound drivers thats the problem and not the graphics card

 

I have the standard realtek one and 1 creative xfi pci express, and i'm having the same "crackling" unless I disable powermizer.

 

i don't have powermizer installed since I did a clean install of win7, is that an optional install somewhere? Not sure about cackling either, when is it heard?

Anyway using the driver above no problems, never tried any other ones to test.

 

strange how its affecting the x-fi card as well.
ive never had a problem with either but i have no idea if powermizer is on or off on my comp. where would i check?

thanks for the link but me not going anywhere near my registry

 

powermizer is always enabled unless you hack your registry to turn it off. it downclocks your gpu when it is not needed to keep it cool and save power. the gtx 260m has 4 different clock settings and powermizer automatically switch through those depending on your usage. the problem is that each time it switches up or down a level it creates some kind of latency spike that affects audio playback (that's when you hear crackling sounds)

so from what we know so far the problem comes from either a combination of realteck drivers and nvidia drivers or nvidia drivers only
