Yes I have the powermanagementenabler.kext there. I removed it to see whether it makes any difference but it did not. System is 3,1.

Also, is it a good idea to get the CUDA drivers for a GTX280? (asking because in the driver details only 285 is listed - perhaps because it's the only officially available for Mac computers)

I mean native power management as explained in this topic
http://www.insanelym...howtopic=225766

It may not be directly related to your problem, but I read nVidia performance can be affected by the model identifier (check Info.plist of AppleGraphicsPowerManagement.kext).

I don't get why you lost performance after 10.6.5 update, though.

Hello oldnapalm,I have NVIDIA GeForce 7025 integrated graphic card and QE/CI works,but I can not change to my native resolution, 1440x900x32.I did try adding graphics mode key to com.apple.boot.plist but it does not work.Do you know how to fix that?

Hi,
DSDT mods supports my gfx quiet good, but don't know how to get GPUPLimit key under ACPI_SMC_PlatformPlugin in my IORegExpl like in real MBP6,1. It is related to gfx PM.

OldNapalm, Would you kindly advise on the following problem?

*GeForce 7300GT card, in Intel dg965wh mobo, Core 2 duo (64-bit)
*OSX 10.6.3 installed w/ TonyMac's "#####", then upgraded to 10.6.5
*as is (booting from #####), the graphics works perfectly: 1600x1200 res, eye candy (QE etc) all fine.

*so, clearly, the 'correct' kexts etc are 'there' for the OS to find.

However.... if I install Chameleon (via TonyMac's "#####"), whether with or without any changes to the boot plist, OSX will boot only into a low resolution (1024x768) with no QE etc. This problem was reported twice on the TonyMac forums, but no solution was offered. (I'm not sure, therefore, if it is a Chameleon issue or a ##### issue.)

What would you suggest I try? Is there an installer for Chameleon that you would recommend?

Sorry, no idea, I never used those installers.

Maybe one doesn't use the "arch=i386" kernel flag? I believe series 7 only work in 32 bit. Or it doesn't enable the GraphicsEnabler option?

OldNapalm, Thank you for such a quick reply. Let's tackle this from another angle: before I try your method (editing the plist), obviously I need to install Chameleon. What method or installer would you recommend for 10.6.5 ??

OldNapalm, Here's the current status; you help is most welcome (and most needed):

*as before, booting into ##### cd then OSX 10.6.5 brings up a 1600x1200 desktop, all parts working.

*after installing Chameleon; booting brings up 1024x768 desktop, no QE etc.

Then, after modifying the boot.plist
*first, as per your guide [shown below]
** then with PciRoot set to "0" (since the autodetect utility you referenced found that value)
***then withOUT the PciRoot two lines

In each case, the system boots as far as the blue screen, and halts.

<plist version="1.0">
<dict>
<key>Kernel Flags</key>
<string></string>
<key>GraphicsEnabler</key>
<string>y</string>
<key>PciRoot</key>
<string>1</string>
</dict>
</plist>

Please help !

Hi oldnapalm!

I'm having trouble with my card=NVidia 9400 M G with cuda.
Installation went fine. Can only boot with -x or -f flags or I get some weird blue flashing screen.
Card is fully recognized in system profiler with full resolution though (but no QE/CI).

I tried many methods:

-Graphic enabler = changes nothing
-Kexts (NVenabler, NVinject, Natit ...) = either loop booting or stuck to blue screen
-addind device ID to NVDAResman NVDANV50Hal repairing permission = either stuck to blue screen or KP
-lizard + editing com.apple.boot.plst = changes nothing (arch is already set to i386 and cpus=1 won't change anything either)
...


I also have a dsdt file that I installed from that topic (post # 30) to fix sound issues.

http://www.insanelym...p...5737z&st=20

Obviously there's gotta be something here, but I don't know how to edit it to match my system?
I found dsdt patching tutorials but it's just too hard for me.

So i'm a little bit confused here?

I can't use EFI studio with my card (not listed and custom won't work).
I can't install strings with os x 86 tool (some error shows up; I read that os x 86 tool doesn't fully work with SL)

No chance to turn QE/CI on with Quartz Debug...

Any idea?

Thanks in advance

Hello chaps,

One very "academic" question here.

I am a GTX280 owner and I installed my OSX via the Kakewalk method. All is good, The card is recognized by the os, beautiful 1920x1200 resolution, sweet ripple effect, the works.

What I keep wondering is, do the apple drivers allow the card to perform at it's best? (assuming that "best"is defined as the card's performance under Windows environment with it's own nvidia drivers)

Since the Apple systems are for the most part less powerful than the current average Windows rig (i5 to i7 CPUs and at least 4GB RAM) I have this mental image of the Nvidia cards being restrained by the Mac OS itself - whereas under Windows they are freed to perform at their best, mainly because of the availability of the manufacturer's optimised drivers, but also because the rest of the hardware allows them to.

In other words, Nvidia cards have more "room" under Windows and therefore perform better, while in Macs they are sort of held back by the Mac hardware.

I guess where I am getting at is, is there a way to unleash the power of an Nvidia card (in particular the latest 2xx and 4xx series) under Mac OS, to match their performance under Windows?

I am happy with the built-in OSX drivers but can we get more out of our money?

Try adding arch=i386 to the kernel flags

<key>Kernel Flags</key>
<string>arch=i386</string>

Thanks again for your suggestions, but this causes the 'gray screen of death' ("you must reboot...").

Can anyone tell me wich kext is specific to the Geforce GT 520? out of the ones included in OS X, I mean. I can't get better resolution than 1280x720 and no proper vram detection either.

Any suggestions?

Thanks ;)

I guess you need Fermi drivers, check update on first post.

Edit: it seems that the 5xx serie isn't supported yet, just in Lion DP4

Hi everybody!

I've installed my new XFX 9600GT 512MB video card with NVEnabler. I've got low points in Xbench:
"Quartz Graphics Test: 260
OpenGL Graphics Test: 189"

CoD4 multiplayer (all garphics settings low/minimum) 60FPS. I think its too low....

What should I do? Use NVInject? Or something else? :)

Under retail 10.5.8

Any update on Lion? NVDAResman does not have the IOPCIPrimaryMatch key; although NVDANHal50 does. When I start up with the devID in NVDANHal, they both show up under loaded extensions in System Preferences, but I still do not get a recognized video card. I also installed NVEnabler 64 but it doesn't seem to be loading on the machine. Any reason as to why this is not loading alongside the included kexts?
