    Natuis, for some reason when I restart the laptop, almost all elements from the NVidia Control Panel main menu (like PhysX, etc.) disappear. But PhysX is still working, the video card performance is always same... I have the full main menu when the 260.99 driver just installed (did it several times to make sure this is not a coincidence), but everything except of 4 major items will be gone as soon as I boot the laptop next time. Not sure why? Have I forgotten something in the INF file?

    I edited the last !edit config on grub4dos to change my disk partition root, i just edited the very last line, i think it's alright cause it actually lets me chainload to windows but i'm really having hard time trying to chainload to w7 when i do the 256mb allocation.

    Can anybody offer some advice?

    Also my System recognizes the gpu NVdia 460 either booting the computer normally or standby/plugging it. However it does show the dreaded "code 43" which nando thinks it's actually because i can't chainload properly.

    UPDATE: I tried 32-bit allocation with external graphics ignored. SUCCESS it chainloaded perfectly and i can now play games with Internal LCD with Optimus drivers 258.96 Now i need to do more repetitions on it to see if it always chainloads and figure out how to use my external monitor.

    This could be problems I have been stating about stuttering. Seems to be Driver issues. Pretty much for me All source games are unplayable. Run MSI Afterburner, Confirm that it is low GPU usage... COMPLAIN TO NVIDIA. Also try running at higher settings to have higher GPU usage.
    Try the Quadro 265.90 drivers from laptopvideo2go website. Made BC2 playable, also made Heroes of Newerth 60 Fps with no more drops with V-sync on.

    gtx gpu usage - Google Search

    According to some people on this Forum they do not have any of these problems. I believe this has been mentioned before, but some people do not have problems with their GTX 460. Any tips?

    In the NVidia Control Panel -> Power Management, change from "Adaptive" to "Prefer Maximum Performance" to see if it makes any difference. You are also running an AMD chipset which might have some bearing on your results.

    I will check out your INF to see if I notice anything out of place.

    I have 265.90 64bit Universal Optimus/Optimus Retrofit ready for testing. If anyone wants to try it PM me.

    I'll download the tests, and should have some benchmarking later today/early tomorrow about my implementation on Acer Aspire 6930.

    Do i have to make changes on setup 1.x everytime i power the computer on? cause it doesn't seem to be working when i save it to the startup.bat file. I might find a way later, but now i'm just stress testing this thing out haha.

    Thanks to Nando who did a little troubleshoot for me when i started this out yesterday!

    Reporting another result:

    Lenovo X201 i5 M520
    4GB ram
    Asus GTS450
    x1 with Optimus

    3dmark06 = 11835

    **Strange problem**
    After installing the optimus drivers provided here, I can't enable aero when running off the card. Any others with this symptom?

    Dell Latitude E43xx/E64xx/E65xx owner's request

    It's been noted here that 36-bit PCI compaction has not been successful on these systems. My previous IGP relocation success was with Win7/32. So I've just loaded Win7/64 on an 4500MHD equipped 4GB Inspiron 1440, finding the following sequence would enable 36-bit allocation of the 4500MHD. Can an owner of one of these systems please test this sequence and report if this works for them?

    1. Boot Win7/64.
    2. Uninstall the 4500MHD or Intel HD driver
    3. Boot Setup 1.x
    4. create pci.bat containing the following line which does a 36-bit relocation of the 4500MHD/HD to the 12GB boundary.
    Code:
    setpci -s 0:2.0 18.l=c 1c.l=3 
    5. Run pci.bat and chainload win7
    Code:
    call pci.bat
    call grub4dos w7
    6. Allow Win7/64 to PNP the 4500MHD/HD.
    7. Reboot, again running Setup 1.x, doing steps 3-5 above.
    8. Confirm 4500MHD/HD is allocated to 36-bit space as shown.

    It isn't working. Even if setup found and compact IGP to 36bit, after chainloading and booting it 'reset' to previous state (32bit).

    Please try the pci.bat given above rather than using compact's pci.bat. The one above is very simple. Ensure too you do the whole process.. ie: uninstall the 4500MHD. I needed to go through this process to get the 4500MHD in the Inspiron 1440 allocated to 36-bit space.

    Consider too rolling back the 4500MHD or Intel HD driver back to the Win7 default.
