Technically we take the GT540M as the point of reference since everyone is familiar with the performance. A rough but more accurate comparison based on Vantage GPU scores.

GT520M = 40-45%
GT525M = 80-90%
GT540M = 100%
GT550M = 110%
GT555M 144 SP GDDR3 = 170%

I got my Black Ops on Steam as well, when they were having 25% off!
Steam sales are awesome.

no wonder GT555M is used in gaming laptops like alienware m14x..

i bought the Black Ops retail box LOL

i didnt know steam has sale for it

The 50% extra SP and memory bus has a lot of impact on performance.

I was about to get retail until I saw that 1 week promo. So just bought it at USD45. Good deal.

hmm, on the m14x the gt 555m is just ddr3, but it's 3gb.

3GB ain't gonna help, even at its higher resolution.

yup, i was wondering that too.. why put a 3gb ddr3 in their gaming series.. shud've ditch the 3gb and put 1gb but gddr5 instead. again dell failed to impress..

1GB GDDR5 is not good, that would mean it only have 128-bit instead the 192-bit in 3GB DDR3...

what's the diff between 128 bit and 192bit?..

Thanks to @skycrawler. Got new Nvidia driver, namely, Verde 275.27 Driver. Its still under Beta. Supports GeForce 8M, 9M, 100M, 200M, 300M, 400M, and 500M-series notebook GPUs.


do u think can improve games' performance? i wanna download it and try tomorrow...see if can improve my bulletstorm performance..kinda laggy


and yeah, what's the diff between 128 bit and 192bit? like what @thiefloard asked...hehe

Tried using QuietHDD to disable APM ?

APM is advanced power management? never try i think.

Your friend's Acer Aspire 5750G is what colour? Blue or Black? First batch or second batch?

First batch is black in colour. It has a lot of problems, faulty laptops. With GT540M 1GB, no bluetooth, EOL-ed. (can change motherboard, full refund, change to second batch....by middle of April)

Second batch is blue in colour. No problem so far. Except just now, when I was replying to this post, my laptop got freezed and I had to press the start up button to restart....so fcking dangerous! Just found out that the Adobe reader updates are making the freeze, disabled it!


so, back to topic. If your friend's laptop is blue in colour, second batch....then try these methods. I played Modern Warfare 2 with my laptop at maximum settings with 60FPS. No freeze or lags at all.


Fix that might help to solve your friend's problem:

1. Update your Intel HD graphics http://www.intel.com/p/en_US/support/detect/

2. Download latest driver for Nvidia GT540M http://www.nvidia.com/object/notebook-win7...hql-driver.html

3. Update your DirectX9 http://www.microsoft.com/downloads/en/deta...6a-9b6652cd92a3

4. If nothing of this work then rightclick on desktop and then go Nvidia control panel then Manage 3d settings then Program settings then click Add and find the Exe u run a game on, for an example GTA4.exe and go on preferred graphic processor and then click high performance Nvidia processor and Apply.


Got this solutions from youtube.

he's is 1st batch, black color..but he already did the cougar point problem replacement..alreaday sent to acer...ok..i tell him ur suggestion.... tq tq wilson

So, your friend changed the motherboard? If the solutions cannot work, better send it back to the shop and ask them to fix it, since it is still under warranty.

Your friend should have gotten a full refund or change to the new 5750G blue colour

but i'd like to know if my suggestions on the fix can help ur friend...
