VGA problem on Acer aspire 4530

Hello all. I am trying to playing PES 2011 and 2012 on low resolution but it was very laggy.
And I am trying to benchmark it using 3dmark vantage but when going on 2nd scene the VGA looks like crash. Whats wrong with it?
Btw my VGA is Nvida Geforce 9100m G. I even try to overclock it using EVGA Precision but the result still same... Thanks

 

There's nothing surprising about it. PES 2012 requires nVidia 7900 (minimum) which has 27 shared units (pixel and vertex shared added) whereas yours has 8 unified shaders.
nVidia 9100 was a low end integrated solution back in 2008 when it was released so you're expectations are way too high.

To put it in to perspective a mobile nVidia 7900 (which is slower than a desktop one which is the minimum requirement for PES 2012) scores some 5900 is 3DMark 05, nVidia 9100 scores some 1600.

So it is several times too slow to meet minimum requirements.

 

Well... So it was because the VGA. But my friend which the VGA below me able to play PES 2011 in low even it can't run PES 2012.
Anyway thanks. Btw is this VGA's notebook (Acer aspire 4530) can be replaced with higher VGA?

 

You can't replace an integrated graphics.
As for your fiends' cards remember than an older high-end card can be a lot faster than a new low-end card.
That was the example- 7900 which is roughly four times faster than your card is also two years older than your card. It's just that 7900 was a high end card meant for gaming.

 

Thanks. I think I must forget playing games for now
