Resolume Forum

After adding and removing outputs I have made a table, because I have been suspecting RAM usage. A this moment I am completely confused..

Fps drops when adding outputs and RAM alocating (usage):

No output - 0 339700k
1st out - 6 fps drop 394200k
2nd out - 7 fps drop 440008k
3rd out - 4 fps drop ...

Thing is, that there shouldn´t be a problem with PCI-E throughput, because when using BM Quad 2, there is 8 of outputs. For uncompressed video, let´s say in 24 bits (reso uses 8 bit or 10 bit) it´s 24x1920x1080x60 = 2,99 Gbit/s per output. With 8 outputs it´s 23,92 Gbit/s.

But PCI-E x8 gen2 (wich ...

Once you activate an output to a capture card, the black texture needs to travel through your machine.
From your GPU to memory, then from memory to your capture card, as uncompressed data.



Yes, but GPU usage is about 30%, RAM usage is only 3,6 GB of 64 GB, processor usage is only 9% to 11 ...

Hey there,

Maybe someone can help or can share some experience..

It´s look like there is a problem with outputing in Reso.


Whats wrong with the sending data from primary (rendering) card to expansion card like BM quad, another GTX, etc.? Why is there a huge performance drop?

There is no ...

Um, well, and how to adjust it for outputs on Blackmagic card, like Quad 2? Outputing squares and also it is visible on advanced output screen when zooming a little bit..

Generally speaking:
If all outputs are on a single card your frames will be in sync. Arena works best with a single super-powerful card.


This isn’t true, gaming cards sometimes are off by a frame randomly. You’ll notice with blends and cuts. It happens rarely but does pop up. It’s why quadros ...

The outputs across the Decklink will not be synced. I have not used one myself, so I cannot speak to tearing. If you are blending multiple projectors, you may notice the offset, but if these are 12 discrete outputs (or have different content across those outputs) you should be OK with the BMD card ...

Hi there,

Nice topic here, so I would like to ask someone with experience using BMD Decklink Quad 2.

When control monitor is connectect to primary card, and all displaying devices (beamers, LED wall inputs, etc..) are connected to BMD Q2, are these outputs synced (without visibe tearing) or not ...

Hi,

Only way to get more videos synced is to merge them to one big clip in premiere, export it like a one file (like 5760x1080) , import it to Reso, do 3 screens in advanced output and set them to different physical outputs..
No matter how powerfull your hardware is, there will be resync after few ...

Ok, thank you for answer.

It makes sense.

So the right way will be to render one huge movie and slice it on output.. No problema..
