I really do not understand what Enrique meant. Enrique, can you
please tell us and explain what is wrong. You already looking at
the pictures, can you please tell me where should i go and change what to what?

Thanks

beingmf3 wrote::lol: Enrique :roll: So which setting is the proper one? How can we know since the "official" Cuda post only mentions FREQD?


CORE6 CPU
TIMED: 5
FREQD: 11
CORE7 CPU
TIMED: 5
FREQD: 25

CORE6 CPU+GPU
TIMED: 5
FREQD: 15
CORE7 CPU+GPU
TIMED: 5
FREQD: 15

5 = SSE
TIMED = Direct convolution audio engine.
Remember Nebula and Acqua Effect are running in hybrid convolution audio engine, based into Volterra diagonal and controlling all parameter with a vectorial engine running always in CPU, loaded from your HDD/SSD to RAM (.N2P files).

Thanks Enrique, as per your quote above and if you look at the pictures my settings are the same as you described:

NebulaReverb is 5/25 and NebulaCuda is 5/6.

But now i get more confused, look what you said here:
Support wrote:TIMED still at 5?

That sounds like 5 is not correct while in the next post you say it should be 5.

I am sorry, i don't mean to be an A$$ i just do not understand what you mean.

Thanks

And i am on Core 7, so to me only Core 7 Settings apply.

OK - just a simple how-to for laymen please.

If I want to use CUDA with Nebula Server Ultimate, then the settings shall be the following:

TIMED _______________
FREQD _______________

Thanks!!

I don't get it, sorry. In this very thread you said
Support wrote:TIMED still at 5? This engine will use you CPU and not your GPU.

Now you suggest 5 yourself!? And why the emphasis on CPU+GPU? Is it an issue exclusively with Server? Would Nebula Pro work better, GPU only?

with Cubase Performance Meters. I opened 2 Nebula Reverb and 2
Nebula Cuda instances on 1 track. Loaded the same preset in all
and then played just thru the two reverb Instances. CPU consumption
in Task manager was 19-21%. After that i switched to CUDA and then
CPU was 9-11%, so basically cuts in half...however in Cubase it is
the same which is a shame...you can not utilize your processor fully.


Hi! I haven't read all the posts thoroughly, but if I have understood you correctly, your CUDA-setup is working but it's not giving you the wow-feeling that it actually takes off some of the strain of the CPU? Is that correct?

I had the similar struggles like you some years ago and finally found out how to set up my CUDA-system. I found out one very significant parameter tweak that gave me the wow-feeling: You have to increase the DSPBUFFER to 8192.

Looking at your screen shots - you only have 512. I experimented with my DSPBUFFER and found out that in my system (look at my signature at the bottom) the best tweak was 8192.

(I have made a special CUDA-instance based on the NebulaReverb.dll with NebulaSetups. Why? Because I usually use 512 or 1024 as my BUFFERSIZE for other Nebula-stuff.)

I can't guarantee any success, but it's probably worth a try?

One more thing:
To see how much of the GPU your CUDA-instance of Nebula uses - press the 'Disk' on the right hand of 'Mast'. To the right of 'BRIDGE' you will see a percentage value. This varies very much depending on what DSPBUFFER you choose. Some figures:

DSPBUFFER: 1024 --------- BRIDGE: 28%
DSPBUFFER: 2048 --------- BRIDGE: 14%
DSPBUFFER: 4096 --------- BRIDGE: 7%
DSPBUFFER: 8192 --------- BRIDGE: 2%

So - when you use DSPBUFFER: 512 - it's not strange if you don't get any benefit from your GPU card...!

Fact: With 8192 I can run several instances of EAR and VNXT with long reverb tails without any problem and have my old i5 CPU doing other stuff.

Try different settings and tell us what figures you get :D

Hope that helps folks!

PS: I don't have the latest Nebula, but I reckon it's probably more or less the same tech regarding how CUDA works?

All the best

Sorry, i really totally can not understand you, its ok i guess
we'll just leave it as it is. I don't know if it is a language
barrier but by you i get confused even more on every response
you make. You give half the answer, you raise another 3
questions and then we are left with more confusion.

A simple answer such as:
''Nedim, go here, touch this and do this''
will really make my life and others easier.

You usually keep going into theories which most of us don't care about.

The last post you made is a MUTE POST. There is NOTHING AT ALL
one can understand. You Colored in Red the 2 numbers and pointed
to Wikipedia...and that was all....what does that all mean in English?

Ok lets try this again in an easier way:
Enrique, Giancarlo, from the picture Below where you can SEE
every info you need on the Instance, is my CUDA and Reverb
Instances setup properly besides the DSP buffer which can vary?
If it is correct please confirm, if it is not please point where
and how i should i adjust it?
