  • 1/3 Decrease in GPU Result between (Driver 296.16 to Driver 301.42)

    I have a Asus G74SX with Geforce GTX 560M 3GB GDDR.

    I reinstalled my computer about three weeks ago with a fresh Windows and installed the latest Asus G74SX Drivers (from the website: Driver 296.16) but then an update came and I downloaded and installed Driver 301.42. I ran benchmark with each drivers, set the Power Options to High Performance so it doesn't reduce anything.

    Driver 296.16 - 2012-05-19, High Performance

    Driver 301.42 - 2012-05-31, High Performance

    See the 28% decrease in GPU results?
    What is causing this or is the Asus drivers "optimized" better, but still - how can almost a third of the performance loss be caused by a less optimized driver? About 5% would be another thing. Also, have been noticing some more commonly stuttering in videos and such since the update.

    Anyone with any ideas?

    I just reinstalled my drivers and again it shows 1920 in 3D results. So there's defiantly something with the driver...

      It is not unusual for video card drivers to have an effect on 3D performance. Normally performance gets slightly better over time however once a new video card is released.

      You could try contacting Asus or nVidia. I would be surprised if you get anything but a canned answer however.

      Does this laptop support "Optimus" with 2 video chips?. Maybe the driver decided to switch to the 2nd video chip. See also,

        There's no Optimus. Asus G74SX doesn't have it at all. Yes, normally drivers can increase performance. But how many times do they reduce performance? I earlier had ASUS older driver (it didn't get updated from ASUS in 6 months or so) and when I finally installed NVidias, the performance went bad. Which is strange... Then a new driver from ASUS came and suddenly, better performance again. Weird.

          It does happen fairly regularly that new bugs are included into video card drivers.

          I think their QA process isn't very good, as there hasn't really been a stable bug free video card device driver release for the last decade.
