Ok...here's my CS4 + video card on a 1st generation Mac Pro running Leopard 10.5.5 story.
I had two 7300GT cards installed and I could turn on "Enable OpenGl Drawing", but only "Vertical Sync" could be enabled under Advanced Settings.
I then installed an 8800GT card in the first slot and left the 2nd slot with the 7300GT card for a total of two cards and 4 monitors.
When I restarted Photoshop with the new 8800 card installed, GPU Settings no longer detected Video Card and Enable OpenGl Drawing was dimmed out.
So then I installed AllowOldGPUS.plugin, and everything worked including ALL the features in Advanced Settings.
What's up with this....? It's my understanding that the plugin is for older cards not newer ones, and that the 8800 should work without having to use the plugin.
So strange, considering it worked with my 7300 cards, which are lesser cards.
Also....anyone have any idea of what all those setting are for in "Advanced Settings"...what they do and if you need to turn them on or not?
I resolved to upgrading to 2-8800s rather than deal with the problems. It seems the Apple OS doesn't not like two different video cards. Things work better when they are identical. I'm still waiting from my second 8800 to arrive. But I'm anticipating much better behavior with 2 identical cards again.
So far I haven't had any problems with it set up that way I have it at the moment.
I really don't want to spend another $300. for another 8800 card just to get this to work.
Especially when you wouldn't be able to get the full speed out of the 2nd slot anyways...quite throttled down...so why put a $300. card in there.
I'll let you know if I start to have any issues with this set up....otherwise you can assume it's working for me.
Anyone have any info on all those Advanced Settings and what they do and if we need them to do it?
While I whole heartedly agree that an additional $300 for a card that won't be running at top speed is really something I'd rather not do, it would seem the only solutions to the issues are:
a) Live without GL features and keep the 8800 and 7300 installed
b) use the AllowOldGPUS plug in with the 8800/7300 and deal with system instability
c) Go back to the 7300/7300 configuration and live without the Advanced drawing and deal with the other known issues.
d) Move to a single 8800 card and 2 monitors to get all GL features.
e) Install a second 8800 so video cards match.
f) Wait for Apple to fix their video driver issues with non-matching video cards.
g) Continue to use Photoshop CS3 with whatever hardware configuration you wish
I have good days and bad days here. At times I can't keep PS4 active for more than 15 minutes between crashes. Usually it's while working on a larger file with many layers and smart objects. Creation of a new layer crashes the application, as discussed in my earlier link. Other days, mostly when doing quick 1-3 layer edits to a file, I have no problems.
Day two here, and just wanted to report that everything is fine and stable here running a 7300GT and 8800GT card together with AllowOldGPUS.plugin installed in CS4.
Mac Pro (1st generation)
2x3 GHz Dual-Core Intel Xeon
9 GB memory
Two internal scratch disks assigned to CS4 (not start up drive)
Enable OpenGL Drawing activated
8800GT in first video slot running 30" Eizo @ 2560x1600 and a 21.3" Quato IntelliProof 213 @1200x1600
7300GT in 2nd video slot running two Samsung 204B @ 1200x1600 each.
Keeping my fingers crossed....everything seems fine contrary to what other people are reporting. I'm not sure why my set up is working, but I'm thankful!
Not yet, Steve. Apparently Apple has had some delays. Probably due to a rush to replace the 7300s. I'm still waiting on the second card. I'll be certain to post my experiences once I do receive it and it's installed.
Chris....I had to use the plugin in order for it to work. Otherwise all the GPU Settings were dimmed out and not available. As soon as I installed the plugin, it all worked.
I would prefer not to have to use the plugin, but what can I do...it seems the only way at the moment.
Quad Xeon 2.66 Mac Pro, 16GB RAM, 2TB HDDs
Photoshop CS4, all panels open and displayed on secondary monitor.
2 video cards - Slot 1 drives a 30" and a 20" Apple Cinema, slot 2 drives an off brand 20" widescreen
Adobe Apps only utilize monitors connected to card in Slot 1. No panels, tools, windows are ever moved to third monitor.
Video configurations and details:
2 x nVidia 7300GT
Open GL active by default but Advanced Drawing disabled (As expected).
Large brushes caused crashes, as noted in Adobe Tech Documents.
1 x nVidia 8800GT + 1 x nVidia 7300GT
Open GL disabled by default.
Installed AllowOldGPUs plug in
All GL features become available, including Advanced Drawing.
Consistent crashing when working with files containing many layers.
Drawing shape layers resulted in a crash 1 out of every 5 attempts with some of my files.
Seems the more layers the more unstable PSCS4 becomes when creating new layers.
Noticeable .5 to 3 second delay when creating layers or committing Layer styles dialog due to layer panel update sluggishness.
2 x nVidia 8800GT
Removed AllowOldGPUS plug in.
Open GL active by default with all features, including Advanced Drawing
Layer creation is instantaneous even on many layered files.
I've attempted to crash PSCS4 several time in the same manner which previously resulted in a crash, but have yet to crash the app.
Overall window performance is better. This is somewhat expected but the amount of improvement was a bit surprising since the second video card is not running at top speed and is primarily used to drive a third monitor not used when working in Photoshop. I'm chalking up the performance improvement to better direction from the Apple drivers no longer being confused by the non-matching video cards.
I finally had to remove the 8800 card and reinstall the 7600. It was not causing me problems in CS4, but was causing computer issues with waking up from sleep and major start up issues.
So I'm now back to two 7600 cards and will just have to wait for Apple to deal with the problem of having two different cards installed at the same time.
CS4 does work with the two 7600 cards...it's just a little sluggish for all the cool effects...zooming, tossing etc.
Don, the two 7300 cards probably isn't the issue with sleep. I ran 2-7300GT cards for over a year without issues. I had sleep issues that were due to a corrupt OS at one point. But reinstalling the OS (ugh, from scratch) fixed all those issues.
Scott....perhaps I didn't make myself clear. I have no issues with the two 7600 installed, that's why I went back to that configuration. I had problems with the 8800 AND 7600 installed at the same time.
Ann....The sleep issue is the least of my problems with those two different cards...I had major startup issues also....like the dock and menu bar appearing on a different monitor and files moved from one monitor to the other, freezes etc.
All is back to normal now that I'm running the two 7600 cards.
I really don't like the idea of spending another $300. for another 8800 card. Especially when the other video slots are so throttled down, its a waste of what the card is capable of.
That would be $600. for cards and another $200. for the CS4 upgrade, bringing the total to $800.00!!
I think I'll just wait until Apple gets this figured out, and hope they do and soon.
One should be able to upgrade a video card without being forced to buy two of them in order to get them to work without conflict. Somethings not right with that.
