1. Re: No GPU Acceleration or MPE benefit (FX3800)
shooternz May 4, 2010 4:00 PM (in response to shooternz)WOOP WOOP WOOP...back up the bus.
Problem solved.
The color bars had a non GPU Accelerated effect on it. Now this was fine until I put the mxf above it and applied the fx.
Then the RED haze dropped over my eyes.
Now running 5 vid layers absolutely smoothly in playback without any red bar
Color Bars
Title
three mxfs (with Ultra Key on each and two oth them are PnP)
Holy moly....

tclark513 May 4, 2010 4:03 PM (in response to shooternz)You beat me to the punch...I was just about to say I bet you are using non accelerated effects.

Curt Wrigley May 4, 2010 4:04 PM (in response to shooternz)I was just trying to dup the problem. I was wondering if there might be a bug with the synthetic clips. After I failed to duplicate it I saw you found the problem. Thats good news. Hey if you get bored of that system; Ill take it off your hands. Mine needs upgrading!

Bill Hunt May 4, 2010 4:07 PM (in response to shooternz)Craig,
You had me worried, as I was looking at the Quadro FX 3800, as my old FX-4500 missed the cut.
Glad that things are looking up. Time to break out the Cloudy Bay Sauvignon Blanc!
Good luck,
Hunt

tclark513 May 4, 2010 4:17 PM (in response to Bill Hunt)It's still en expensive card for only three layers. The GTX285 does three layers for a lot less money.

shooternz May 4, 2010 4:53 PM (in response to tclark513)What do you mean only3 layers?
I now have 8 running smooth as silk. All have ultra key fx and pnp and some have CC.
I think you have it confused.

7. Re: No GPU Acceleration or MPE benefit (FX3800)
tclark513 May 4, 2010 5:07 PM (in response to shooternz)Not confused. The three layer limit was stated in another thread. I'm glad to hear it was wrong.
How are you planning on running your monitors with only one output?

8. Re: No GPU Acceleration or MPE benefit (FX3800)
shooternz May 4, 2010 5:14 PM (in response to tclark513)Yep ..it was absolutely wrong
Now...you seem to have the wrong info again!
My card has two display output ports ( and a 3rd which is RGB).
I also run externals via F/W.

These show different:

shooternz May 4, 2010 5:25 PM (in response to tclark513)I can see three outputs on it like mine ( LeadTek)

tclark513 May 4, 2010 5:36 PM (in response to shooternz)My bad...I didn't see the adapters.
I wish the poster who said this card had a three stream limit would have been more accurate. I would have put up the extra 300.00 over the GTX285.

12. Re: No GPU Acceleration or MPE benefit (FX3800)
Bill Hunt May 4, 2010 6:11 PM (in response to tclark513)It seems that at least one such poster has been called to task for similar comments in another thread.
What we need at this point in time is information, and not mis-information.
Good luck,
Hunt

13. Re: No GPU Acceleration or MPE benefit (FX3800)
ECBowen May 11, 2010 8:37 AM (in response to Bill Hunt)I was the one who posted it because that is what our Nvidia rep said. He said the Quadro 3800 would have the same
3 layer limit as the 285GTX due to the 1GB ram on both cards. If that is incorrect then the information they gave me was incorrect.
BTW I will forward them this thread and ask them why they informed me otherwise. Thank you for the heads up.
Oh one last thing. Nvidia and Adobe stated the limiter was put in place because of the 1GB Frame buffer size limited performance in CS5 and they could only ensure performance with effect for 3 layers. If the Quadro FX 3800 is unlimited then that is completely false. Since the Quadro FX 3800 has a 260GPU in it and has 1/3 the ram bandwidth of a 285GTX then how does 1GB on the 285GTX require the limiter but the 1 GB Quadro card does not. This means Adobe is completely working with Nvidia to sell more Quadro FX cards and the limiter is a completely dishonest way to do it.
Note - After checking my email and speaking with my Adobe rep I changed the post. It was only our Nvidia rep that reported the limiter on both.

ECBowen May 11, 2010 3:43 PM (in response to ECBowen)Since I can't post what I have discovered in regards to the limiter or what I have been told, I can ask a question. People who have the 285GTX, please comment on your experiences or feedback with the limiter positive or negative. I will forward them to the appropriate parties.
Please post your responses in a new thread I created

jssink May 12, 2010 9:21 AM (in response to shooternz)Hey shooternz - Are you running your preview monitor off the third output?

16. Re: No GPU Acceleration or MPE benefit (FX3800)
carny_ May 22, 2010 12:54 PM (in response to jssink)The quadro 3800 can only utilise 2 out of the 3 ports at the same time. So if you want to run two monitors for the program and a third for a preview monitor then you need two 3800s installed, unless there is another solution. Especially now that firewire preview isn't working with MPE yet....
I have two quadro 3800s installed and can preview off the second card.

shooternz May 22, 2010 9:07 PM (in response to carny_)Not exactly sure how you are getting two video cards to run (considering no SLI Support) but...whats the chance you could mis-match a set of cards together and get a result such as you are experiencing?
eg An FX3800 and an FX1700

18. Re: No GPU Acceleration or MPE benefit (FX3800)
carny_ May 23, 2010 3:53 AM (in response to shooternz)Not sure if that would work, i would imagine that two different cards would cause a problem, worth a try if you can borrow one... I have an sli connector connecting the 2 cards but no sli option in the control panel.
I don't think i'm getting any performance increase, although i haven't tested properly yet. Perhaps its just using the extra card to display the results of what the first card is doing?
According to nvidia the card is sli capable, but I've not found anyone who has successfully set this up yet.

19. Re: No GPU Acceleration or MPE benefit (FX3800)
carny_ May 25, 2010 8:28 AM (in response to shooternz)After a bit more testing I'm not sure whether you need the secondary card to be the same as your primary CUDA one. This should work with any decent secondary graphics card on a suitable workstation (I think!).My primary FX3800 card outputs to one monitor for the program and one preview out (via a dvi/vga to s-video converter box) to my CRT broadcast monitor.
Then my secondary card outputs my second monitor display for my dual screen setup. essentially its a three screen setup as my crt is always displaying part of my desktop until Premiere previews through it. This is actually more useful for me as it gets more use than previously through firewire, As I can make use of it when not using Premiere or AE.
Then If I need to export to tape I'll have to switch to software renderer but hopefully that will change in the future.
Initially I tried to preview out to my CRT through my secondary FX3800 but I found I was dropping frames (on the CRT monitor not the program monitor) so I assume that MPE is only working on the primary card as theres no sli support for this card on my system.
So far so good and haven't run into any problems (yet!)
(this is edited from a post i made in a similar thread on the MPE)
Hope this helps although unfortunately I can't test it with mismatched cards.
