Nvidia Driver 275.27

It's not uncommon to see 10-15% performance increases with Nvidia drivers- especially on relatively new hardware (they won't be as great increases down the line). The 485m is still a new piece of technology, relatively speaking, so driver support will get better for a while before petering off into limited increases/stability tweaks for new games.

 

with 275.27beta the gtx470m play the ultimate excellent game 《withcer2》, 30-40fps in below configs:

=========================================

and 48-60fps (55fps average) in another ultimate excellent game 《crysis2》 in configs:

(when push F button to destroy the alien cores in the park in last stage , old drivers down to 30 fps and new 275 reach 48 fps , and in many scene the lights and shadows seems better than 270.61 beta)



=========================

overclock status in the signature

=============================

win7 experience index is still 7.5

machine is w860cu

 

i can also confirm a 7.6% increase in 3DMark 11 score after finally being able to update from 270.61 to 275.27
aside from that, minor increases by 1.5% max. in unigine benchmarks, 3DMark03 and 3DMark05.

cheers

 

You guys are tempting me to upgrade...

Is there any risk going from WHQL to beta?

 

Yes, there's a chance it won't play nicely with your hardware/software and you may need to roll back the driver (For various reasons) or do a system restore.

Technically speaking, a beta driver could kill your GPU, as it's happened once before

But it's obviously something along the lines of seeing-a-unicorn rare.

Worst case scenario it doesn't work well with games. I had to roll back on the Lotus P150HM that I run because Settlers 7 had some graphical issues with the new driver.
