    Discussion started on My discoveries on VaioZ's Hybrid Graphics. but I think that it deserves new topic.

    Optimus is new technology from NVidia that will greatly simplify hybrid graphics solutions for users and manufacturers.

    Here are some links:

    http://www.nvidia.com/object/optimus_technology.html
    http://www.anandtech.com/mobile/showdoc.aspx?i=3737
    http://www.youtube.com/watch?v=Fdb2VrUdT4k

    From my point of view as future Z owner, most important thing about optimus drivers is not been dependent on Sony for NVidia drivers, especialy now when Z is more capable gaming machine.


    For start this is what our road worrier Zoinks manage to do so far:

    Also here are some advices form Nautis on tweaking inf file:

    We are not sure yet but seems like Optimus drivers are working on the new Z.


    EDIT: Nautis opened section on LaptopVideo2Go related to Optimus on new Z and other Hybrid Graphic laptop candidates:

    http://forums.laptopvideo2go.com/topic/26410-optimus-drivers-on-the-vaio-z/page__pid__128386__st__0

    EDIT: Latest, most successful instructions so far from Nautis on optimus enabling for Z11

    Download the latest Intel HD drivers: Intel® Graphics Media Accelerator Driver for Windows 7* 64 and Windows Vista* 64 (zip)
    Download the Notebook 257.15 drivers: NVIDIA DRIVERS 257.15 BETA
    Switch the tri-selector to SPEED
    Uninstall the Nvidia drivers, reboot
    Install the Intel HD drivers, reboot
    Extract the Nvidia notebook drivers, delete all INF files in the Display directory. Download Nautis' modified INF (rename from .TXT) and place in the Display directory
    Install the drivers, reboot

    Results:
    Windows boot - fast, issue resolved
    Context menu option - working
    Automatic GPU switching - working
    Graphics overlay - Demo text remains
    Function key brightness - Working

    Hi, Igorstef!

    I think you've unintentionally said even more than you meant. Indeed, nVidia's Optimus is more like "theology" than it is technology, at least for Vaio Z11xxx owners. While it's quite beneficial for folks who don't already have the ability to switch graphics technology on the fly without rebooting, folks who insist on this for the new Vaio Zs surprise me. Reaching all the way across the keyboard (say 3 inches for most folks) and waiting one second are far too annoying? While nVidia's come up with a cool little DMA hack here, was manual switching really that painful for you? Zounds! ;)

    Cheers!
    Mark

    Hi, igorstef. Thanks for the detailed instroduction of the optimus driver.

    But after installing the Nvidia Optimus driver,

    1. Will I have to start the machine in "Auto" mode? Or what will happen?
    2. Will the tri-switcher still properly work in Windows 7?
    3. CURRENTLY, is the graphic card performance under Optimus driver better than or at least similar to the Sony driver?

    Sorry Mark my English isn't that good (I am relying too much on spell check ).

    Anyway I actually prefer manual switch on new Z since switching GPU based on application is more gimmick that real life feature. If we ever make it work properly on new Z I will set profile to mimic Z auto switch.

    But as you probably know Sony will release new hybrid drivers and therefore NVIDIA drivers usually when Microsoft release new OS :). You will not be able to use new GPU drivers from NVIDIA site. This is unexceptable if you plan to play some games on Z. This is my main reason for trying to use Optimus drivers so I can avoid playing with ini files in order to make Sony hybrid drivers to work with new NVIDIA drivers.

    1. I am not sure, Zoinks can tell us this.
    2. Nop since Optimus work without using multiplexer. That said, maybe somewhere down the road we will be able to set custom functions for hybrid switch.
    3. Curently GPU performs identicly under Sony or optimus drivers but if NVIDIA do any updates on drivers for 330M you will have to wait on Sony or some other 3rd party to update hybrid drivers. With Optimus drivers you dont have that problem.

    As I already said we are not sure if Optimus even work with new Z. Zoinks will need to do some more tests for us if we want to find out.

    Hi, Igorstef!

    No sweat (meaning no problem at all - that no apologies are necessary)! I was just yanking your chain (meaning that it was a fun joke with you - not against you)! Indeed, hearing your reasons, this path of exploration makes complete sense, and I completely agree with you on your conclusions. I too prefer manual graphics switching over any program telling me when I should.

    With regard to English skills, trust me that whatever your native language is (Russian/Eastern European?), mine are far worse (as in almost none). You're doing great! :)

    Best Wishes!

    1. Nothing, the tri-selector isn't functional but that is kind of the point with Optimus
    2. See #1
    3. I haven't benchmarked much yet. All I can say is that the auto-switching seems to work.

    Great, thanks Zoinks

    Hm Interesting :). Seams like Optimus drivers are ruining in demo mode on vaio Z. Maybe that is also reason why Z is straggling with rebooting.

    Seams like task for Nautis :). We need to find what is forcing optimus to demo mode when those drivers suppose to be production version.

    For mine, I must remove password login on welcome screen althrough the screen will get blank.

    I have 2 question
    1. Can i get "Run with graphics processor" on right click menu as you screenshot?
    2. Now we can't remove "Optimus Demonstration..." text yet ?

    PS.
    - My windows user profiles have lost on first reboot.
    - After second boot everything seems fine but the fan get very loud and speaker have some noisy sound on windows startup
    - Sometimes the system hangs after around 5 minutes
    - Mine is Z117GG (1920x1080 screen)

    Thanks for your answers.

    So I decide to learn how to install the optimus driver first so that later I could try. But I won'd actually do that until some newer drivers in the future are approved to be better (in terms of function/performance) than the SONY one.

    1. Read this: http://www.pcper.com/article.php?aid=868&type=expert&pid=4
    2. Not yet, I'll try some stuff when I leave the office

    On the PS's:
    • I don't have a password on my machine
    • No extra fan noise on mine
    • I ran with the Optimus/Intel drivers all day yesterday, no problems or hangs
    • I have the 1600x900 screen until the VPCZ11FHX/XQ ships

    Ok since this seems to be the new topic on Optimus Technology working on the new Vaio Z I will continue posting here about it.

    I have seen a lot of talk recently on the benefits of Nvidia Optimus vs Hybrid Graphics (aka Switchable Graphics). A fantastic video put out by Nvidia showcasing the differences can be seen here. Optimus is basically Nvidias evolution of what they were trying to accomplish with Hybrid Graphics technology.

    One of the largest differences between Hybrid Graphics and Optimus on the driver side is one of its greatest benefits. Optimus drivers are stand alone drivers released by Nvidia. No more smuged together Intel/Nvidia drivers in one package. What this means is no more waiting or having to rely on the notebook manufacturer to release new drivers. With over 20 notebooks announced using Optimus technology and it being a core feature of a few of their newer GPUs (ION2) Optimus will (hopefully) be a focus for Nvidia rather than just an afterthought (like Hybrid Graphics.) I predict most new drivers released by Nvidia will have Optimus support built in. All that may be needed is a simple modified INF like most are using for their notebooks already.

    --

    Modding the INF the way it says in the first post forces the drivers to use settings configured for Asus/Medion notebooks. Since as far as we can tell Optimus seems to be working I will look at creating a new INF with settings geared towards the Vaio Z. Chances are the issues you are seeing now are due to settings in the INF not for the Vaio Z.

    Thanks Nautis. Changing inf files should be all we need to do since I don't think NVIDIA is planing to build drivers for each laptop, that would defeat the purpose of Optimus drivers

    So Optimus is something like Add on to Intel and NVIDIA GPU drivers. Great work Zoinks.

    Yes we need to see if you can achieve same battery life with optimus as with Z hybrid drivers.

    This should be running with just the Nvidia GPU and not the Intel one. Interesting though. I will explain more later, I am putting finishing touches on a new INF. Optimus may be included in future LaptopVideo2Go INFs but as of right now the proper strings are not there to enable it.

    EDIT: I am going to take a look at 197.15 and see if it includes all the proper files. If it does there shouldn't be a problem enabling it.

    Thanks

    Looks like I spoke too soon. 197.15 left the context info there, but killed switching.

    I'm back to the original Optimus for now.

    Slow boots and Demo overlays are back for now.

    I uninstall all old drivers then install intel HD graphics follow by Nvidia 197.15_desktop_win7_winvista_64bit_international and path INF from LaptopVideo2Go from here http://www.laptopvideo2go.com/infs/195series/19715_win7x64/nv_disp.inf

    When right click on desktop it show both vga menu but in nvidia control panel i don't see optimus menu like before
