It still has about half a second of latency.
I have included a screenshot so you can see my settings.

Yes go into the Master page and change the DSP buffer
Note for Cuda you need at least 2048 if I recall correctly I have mine at 4096


It makes no difference, still about half a second of latency.

I noticed that there is a parameter in the DISK page that gives a number percentage describing CUDA usage. It is a good way to see if CUDA is working ok.

Are you experiencing any latency? what are your settings on the master page, If you would be so kind ;)

Someone also suggested making a copy of the NEBULA3 REVERB plugin and xml filse and renaming them to something CUDA related.
I did this but the new plugin does not show up.

What I should do for run Nebula under CUDA?
1. Have a CUDA GPU.
2. Install a CUDA enable GPU driver and CUDA Toolkit version 3.00 (please use C:\ not C:\Program files in PC/Windows OS).
3. Install Acustica Audio CUDA Bridge version 1.1.036.
4. Copy the "Nebula3 Reverb.dll" file and rename it "Nebula3 CUDA.dll" or choose a name that you like.
5. Copy the "Nebula3 Reverb.xml" and rename it as above (e.g. "Nebula3 CUDA.xml")
6. Load Nebula3 CUDA and go to the MAST page and set the FREQD to mode 15 (CUDA 2ch Mono), then click in SAVE.

Also that last step(6)..
set the FREQD to mode 15 (CUDA 2ch Mono), then click in SAVE.
I do not have that option.
14 (CUDA 2ch Mono), is the nearest thing to it, but none of these seem to solve the latency problem either.

Sorry for such a long post.
I have tried everything suggested so far..
I also read and tried the
AA CUDA Bridge upgrades posts
http://www.acustica-audio.com/forum/ind ... =viewtopic
but no luck.

Right, I re-installed all CUDA software, making sure that I downloaded and installed the correct versions.

1) Install Nvidia driver.
2) Install Nvidia CUDA toolkit v 3.00. (not version 3.10)
3) Install Acustica Audio CUDA bridge v 1.1.036.
4) Run Nebula.

The latency issue is gone now ;) (it was due to the fact that I installed Nvidea CUDA toolkit v 3.12 by my mistake)

The problem now is a very distorted crunchy sound when I am using MOST of the reverbs.
(I managed to get the "RV tight room" working with these settings..

)

I am still testing, but it looks like all the other reverbs are unusable at present.

Any ideas?

Hey Markg:

I've noticed that you have the "*L FreqD" set pretty low in both pictures you've posted.

You'll need to increase that (probably as high as it will go) in order to hear the full tail of the reverb program.

Oh, and generally speaking it seems to be a good idea to turn "Rate CNV" up to at least 3200.

regarding latency: yes, I always experience latency using the REverb version, but my host (Logic) compensates for it just fine. I also use Pro Tools9 and it will compensate, too.

I haven't tried setting the DSPbuffer super low since setting up CUDA- I will mess around with that.

Thanks for your replies, I will try them out and get back here to show results.

meanwhile when I try to use the regular nebula3 plugin (not reverb)
i get this screen..

and then logic crashes.

I have all my .ser and authorization files sorted.
I am being patient but, this is getting silly now. ;(

Well I have done the whole thing from scratch again.

Downloaded the recent setup for nebula
reinstalled nebula
sent of my .ser file (waiting for KEY response now)

Nebula is working again but even after following ALL the advice given I still have bad latency issues with CUDA.

When I use PLUGIN DELAY COMPNSATION in logic - Nebula3 reverb acts like its in bypass mode.

I am just hoping there is an answer out there somewhere.

1. Use this setting under Nebula reverb version:
OPT TIMED: 5
OPT FREQD: 15
L FREQD: 6.000s
RATE CNV 4500.00 ms
DSPBUFFER: 2048

2. Reinstall your customer KEY for stop Program #0 invalid error, Is KEY error type 4 from Key FAQ.

3. read this:

I am using OSX - the instructions for making duplicates are for PC.
I tried by doing the obvious (to a layman) conversions.
ie PC dll = OSX componant
but it did not work, which is why I asked here to start with.
