GPU combination

PostMon Aug 19, 2019 5:14 pm

Hi, I run a Titan x, Pacal, 12 Gb, together with a GeForce GTX 980 .

Now, after I started to edit DJI Mavic 2 files, 10 bit, 265 , 4k, I get the message " you GPU memery full"

I want to upgrade, and just want an advice what card to get.

Will it be the best solutuion to get another GTX Titan, and link them togeher ? or take out both and get a nes setup ?
I have "only" a Intel 5960X CPU and 64 Gb RAM, maybe I need a nes CPU too ?

- X99A RAIDER, - 2011-3
- RTX 2080 Ti ( Titan x ( pascal) )
- Allen Heath QU 32
- 2 x WD 4TB
- sctratch : PM961 SSD M.2

Take the 980 out first and check.

I took out the 980, and the Titan x alone performed a lot faster actually ) but .....


I think the timeline view slowed down, after I updated to the 16.1, beta 3 . any one knwos why .

And, after I installed my new card, took out the Titan x, installed the new RTX 2080 Ti, the card bought directly from Nvidia, I see absolutely NO improvments.

I run teste with and with out optimized, and cach on and off .

what a wast of money, should I return it ? Or will DR take use of the newer technology inthe 2080 ti, in later versions ?

.....I guess its no point in putting the two toghether, I will try anyway but...

The Mavic files are so compressed that the bottleneck is more likely to be your CPU

DJI Mavic 2 files, 10 bit, 265 , 4k


How is the chroma subsampling of those files?, 420 can make use of hardware decoding by the GPU.

When I edit 4k, mavic 2 files, they run smooth, also like the footage from sony a7s II .

that, fo course alone with no effects and NR .I run those in 4k , in the timeline .

But I fall down to about 2-3 fps, when I add some NR, and 4-5 nodes, with 2 plugins, like flicker, shake .

But I mean, when I turn on the Use optimized media, and render Output color, an maybe also use 1080 in the timeline, it works quite ok .

Maybe the CPU can be changed, I dont know if this motherboard will fit a bigger CPU .

The easiest way to edit your material is to convert it to cineform https://blog.frame.io/2017/02/13/50-intermediate-codecs-compared/ or use 1080p cineform proxies.
h265 10 bit is not really suitable for editing(to compute heavy).

@james tell

It is very true that it is better to transcode its H265 in a lossless codec.

BUT check your PC :
I practically have a PC like yours:
D.R - 16 Studio:
- Windows 10 Pro 64
- 64 GB RAM
- X99 II,
- RTX 2080 Ti
little difference
i7 - i6850K vs i7 - 5960X

I'm able to have a DJI Mavic UHD / H265 / 10-bit clip
in a project with TL UHD

Color page:
node 1 = TNR 5
node 2 = some LGG
node3 = OFX deflicker
node4 = ofx Camera shake

and reading in the color page at 15 fps.

Normally you do not have to have a GPU FULL because at most you will have +9 GB VRAM

I recommend you install the NSD driver 431.86 and proceed to a custom installation + clean install :)

ok, great thanks ! a lot . Just by a coincident I foundt that, and this is imprtant, ( for some)

I used both shake and sone flicker in my musicrelease project. I bypassed the nodes, and saw, DR went from 2-3 fps til 19 !!!

So, what did I find . The plugins was from Igninte ! I bought them long time ago. I tried DR s own similar plugins, and they dont steal power at all !!!

Any way, I took out the Tian X and installed 2080 Ti, and compared. And I dont see a lot of differance though . I use only H.264 and H 265
XAVC S, sonys format . I saw befrore about transcoding, but that takes lot of time, And to code over to other DR friandly fromats take extremaly lot of space too .

thaks for helping me out on this. Yes the driver did some improvements. I don tthink I can transcode to cineform ? I use Win 10. I see recomandation to optimize to DH - HD .HQ for this SONy formats .

Plugins external to BMD are not necessarily optimized GPU ( :?: ), BMD yes ...

Some prefer cineform, others not: you have to test what is best for you? 10, 12 bits? Format sources?
Is it useful? reasonable? :)

I've been frustrated with a performance drop issue on my i7700k / RX-580 after installing BM video card drivers which removed the OpenCL driver for my CPU chip's display hardware. Uninstalling the driver wouldn't allow me to re-install it.

Anyway, check out the GUI box in the configuration settings. I stumbled upon a youTuber who added a 1070 card to his 2080 ti for only running the gui and that sped up rendering! So, I'm thinking that my motherboard graphics were handling the user interface work just fine, allowing my RX-580 for dedicated compute work. When the driver was removed, I had to plug my monitor into the 580 and my performance suffered.

Here is John's video:


Is there any guidance from Blackmagic on all going on under the hood? They suggest only using the same model of cards, but the video shows that it's more complicated than that. Also not supposed to mix architecture of cards, but my mixing of Intel and AMD had worked (once both had drivers with the same version of OpenCL) until sabotaged by the BM Declink driver.

If that's correct, then why not take your RX-580 graphics card out of your computer and remove its driver and then download the driver, from Intel, to your Intel HD Graphics 630 graphics card?
