Major issues here with Gigabyte Radeon 4850 512MB; installing update resulted in graphical garbage after the Apple logo disappeared. Started up in safe mode and installed ##### Radeon 4800 10.6.4 kexts again, resulting in kernel panics. Argh :thumbsup_anim:

Started up in Safe Mode and installed netkas' update -

http://netkas.org/?p=515

And thanks to him, all back to normal. Since I couldn't see the SL Graphics Update 1.0 installing, I don't know if it actually updated - however, it is no longer available in Software Update, so I assume it installed.

Most (or all?) 4850 cards needs ATI4800Controller.kxet, ATIFramebuffer.kext, and ATISupport.kext from 10.6.2,
I guess you forget to backup them.

REBOOT

this is added in boot.plist

"I still need to plug in an DVI->VGA adapter on the unused DVI port. Try this if you get a black screen instead of proper graphics." 10.6.5 --> fixed

no problems with the update here, 8800GTX detected via dsdt.aml, gave me a performance boost in all my mac games (wow, source-engine based games)

EDIT -- This update makes no difference for me. Identical cinebench Framerates eg 14.5 as MacPro4,1 and 30.18 as MacPro3,1. I get a prompt to install a (non exisitant) update for CUDA on boot, but mecury still work in CS5.

So this is a weird one.


UPDATE: I've now also tried turning off graphics enabler and using a gfx string generated via aquamacs guide. the string works but same 50% reduction in frame rate as MacPro4,1.

Im using a bone stock PC EVGA 285 with graphics string in my boot.plist

Im not sure of any instability issues. I played SC2 last night for about an hour without a hick up, but each system/setup is a balance of different factors.

Would you post your graphics string?

I installed Snow Leopard Graphics Update 1.0

It updates the Nvidia drivers from 19.5.8f01 to: 19.5.9f02 and CUDA will prompt for an update with these drivers (if you have CUDA installed) but an update is not available yet. This issue is well known on NVidia Forum but till now
without solution.
In my case I loose hardware accelerated Mercury playback engine in Premiere CS5. And need to reinstall Aperture.
After that I reverted to old 19.5.8f01 Apple driver and everything is OK as before.

Certainly, its the string included in DD's Script.

For some reason GraphicsEnabler never worked for me so I've always had to use the EFI string.

Also I just checked on CUDA in my preferences and a new update is out 3.1.14 I'll report back if it changes anything.
Edit:
No noticeable improvements performance wise, but nothing broken either, at least for me.

The CUDA update improves performance slightly for me.

I had experimented with the same EFI string, but without performance improvement.
My theory is that your EVGA vendor ID is being picked up by the driver, but my Gigabyte one isn't.
Are you using the AppleGraphicsPowerManagement.kext from 10.6.3 or 4?
Would you run the following command and attach the output (or just the display@0 and subtree section of the output)?
ioreg -lS -w0 >out.txt

I think this is what your wanting, let me know if you need more of the txt file.

I did get about a half a fps improvement but I figured that is within any given test tolerance.

As far as kexts go im only using 3
fakesmc (from your power management thread for fan control)
ALC889a
RealtekR1000SL

I've got a Galaxy GT240, and get screen garbage (all white with speckles) once the machine finishes booting - but it's running, and I can ssh in. Safe Mode boots OK (sorta) - any suggestions which kexts to remove to get it working at least as well as before the update? :D

I was looking forward to better Aperture performance, too. :(

Thanks, would you attach the Info.plist from your AppleGraphicsPowerManagement.kext?

Ditto for me. I don't seem to have an AppleGraphicsPowerManagement.kext, at least not in the system profiler kext list.
Does anybody know if this update has fixed the Nvidia performance issue for real MacPro4,1s?

No, but removing AppleGraphicsPowerManagement.kext has the same effect as using MacPro3,1.

What 'effect' is that?

I've been using MacPro3.1 for my Pentium D D945GCZ ICH7 system with 9500GT video, but have lately been wondering if it was the right choice.

Those of us with X58 hardware (MacPro4,1) and a GTX 285 had a performance decrease with 10.6.4.
What I mentioned were two workarounds.

Sorry for the delay d00d just got home from work here is the info.plist you wanted from the AppleGraphicsPowerManagement.kext
Sorry I had to attach it as a .txt, it wouldn't let me put it up as a .plist If you need it in .plist feel free to pm me

So, if I read this right, the AppleGraphicsPowerManagement.kext has an entry to corresponding to nvidia deviceid 05e2, (a GTX280) but it looks as though your GTX285 has a device id of 05e3. so the kext would not try and modify its behaviour?

Just wanted to follow this up - I have a somewhat weird setup (due to not being able to boot off my main disk), and I had a lurking .mkext file I had to trash. Booting fine now!
