use the overlay, it should show optimus on upper left...

What about if medium settings or low settings? If the fps didn't change much also, means i5 450M is not enough
That's the default driver...
latest is 8.17.12.5896..

did the "optimus" word shown?
use the NvOptimusTestViewer
check both option...

It should have big word Optimus on the upper left screen when run in games...

Even with the default driver, it also shown the word....

Don't close the apps...
Tick the show overlay..

Nope, it still soft no matter what I did....

any specific situation when it hangs?

Can try use back the default gpu driver?
If that's the only changes you made recently....

Simplest way would be using the recovery.....
To make sure whether its software or hardware problem...

set to power saver using power4gear?

You would need to set lower settings....

No other try overclocking?

To make your component to run faster than its designed for.....
Risk, more heat, dead gpu(should be less since not playing with voltage mod), unstable machine...

So far option to overclock A42Jv is to run i5 450M@2.8GHz, Turbo to 3.2GHz or i5 450M@3.0GHz, Turbo to 3.3GHz and overclock the GT335M....

In average around extra 10fps for L4D2
didn't test other games...

Reaching 90+C, though the stock clock also almost reaching that temp, so not much addition, with no cooler, standard room temp....
Palm rest still cool...

Yup...

Don't those kind of headphone using two plug?
I think easiest is use the usb headset..

That is how Optimus works....
Nvidia OFF : Intel (compute) - Display to screen
Nvidia ON : Nvidia (compute) - Copy result to Intel - Intel receive the result - Display to screen...
Intel will always output to the display...
This is how Nvidia is supposed to remove the flicker and blank screen when switching issues found in the older way in hybrid graphics...

Compare side by side, the palm rest even cooler than my Acer

You need to install MSI AfterBurner 1.60
then after installed, go to its directory under the program files(x86), open the msiafterburner.cfg if not mistaken, then scroll down, change the enableofficialoverclocking = 0 to 1 then save it....

then open the msi afterburner, from there, you can slide the memory clock and core clock...
core clock gives more performance but more heat...
Try adjust core clock first, try at first 50MHz, then go up slowly by 10MHz or 20MHz, each of it, test it using furmark couple minutes, check whether there's artifact or not, then keep slide the core clock up untill there's artifact or hang, then put back the value slightly lower before it hang, e.g if it hang at 820MHz, put it around 800 or 810MHz... then repeat it with memory clock....
The best I could get is Core Clock 577, Memory Clock 966...
with i5 450M running at 3.0GHz, 3dmark06@1366x768 gain 9088 score from 7200 in stock clocks....

CPU, GPU, design, brand, price? and its A42Jv...

What about other fn combination? Did you disabled ATKdriver?

What improvement are you hoping for?
