Good evnin'...

Now that DRS 15.0.1 is out I hoped that the GPU memory full issue would have been addressed...but nothing the like...

Many people here with a 6GB or 8GB GPU are seeing this error in Fusion even if "Run Fusion on CPU" is always turned on...So what does actually fill up the GPU RAM when only CPU is involved?

Do others see the problem as well with GTX and Radeon R5xx card with 8GB or 11GB GPU RAM?

Makes absolutely no sense in acquiring a 11GB Radeon/GTX/RTX card when the problem still persists.

I get this only when I add a few third party VFX to the time line. However, if I reduce the timeline playback resolution to 1/4, then it the GPU Memory error goes away.

BTW: I am on Windows 10 x64, 32 GB RAM and 8 GB GeForce nVidia

This with Fusion on CPU or on GPU?

So this leads to the assumption that Fusion doesn't use the CPU but fills the GPU RAM for caching the timeline?

Hmmm...wonder why HitFilms Pro requirements are so low compared to DaVinci Resolve Studio:

RAM: 4GB (8 GB Recommended)
Video memory 1 GB minimum (2GB or more recommended for 4K UHD.)

Sad it isn't available for Linux....

How does Lightworks behave in CPU/RAM/GPU requirements?

Lightworks is lighter too…

I would like to see some feedback from someone with a GPU card with 11GB or more RAM if the memory error also exists there or not...

No one here with a GTX10180 TI 11GB? (o;

Anyway, we shouldn’t need a 11 GB GPU to do decent work in Fusion. I mean, come on, my 8 GB machine crashes with a HD timeline!

Hi
Definitively, GPU memory error also with 1080TI (11GB VRam) and 15.0.1

Thanks for testing

Well I had a quick look at HitFilms Express on macOS...no Linux version...
The UI looks somehow unusable to me....and looks ugly as well (giant buttons on a UHD screen don't look good ;o)

Installing now Lightworks on Debian 9....

Eeek. I upgraded from Beta to 15 and now Resolve hardly works at all - includes that GPU full error message. GTX780 6GB. It went from perfect to terrible? Presumably I should just reinstall the Beta?

Wonder if their eGPU device also throughs those errors...

No one from BMD listening here?


For me I am investigating Lightworks and HitFilm Pro for that matter...

They are listening, but it's clear that the Fusion integration is still a work in progress, while Fusion standalone is a great tool.

@Trevor: what exactly are you trying to do? I'm not sure we are talking about the same problem.

I'm just trying to play a few 4k clips on the time line. Nothing else.

That's a different problem then. Please post the error log for BM to look into it.

I tried a dual clip compositing with speed effect in fusion, 4k material and it never crashed on me. (System in Sig)

But I'm not a BIG fusion user, more of a noob...

Hmm....do you guys still see GPU memory full errors with Resolve Studio 15.1 now?

Tried the particle particle dissolve text example from the youtube tutorial again and GPU is around 20% used (of 6GB)...
and it uses GPU for rendering (I believe)....and GPU RAM fills up to 62%...

Also there is no "Run Fusion always on CPU" setting anymore..

It runs fine for me too, even if I up the particles 100 times.

Ah good to know....also as you are using Radion GPU....
I assume it balances now between CPU and GPU as the CPU setting is missing....
Release notes don't reveal anything though...

Now waiting for GTX prices to drop

Don't think if a RTX would make sense as raytracing wouldn't benefit in davinci resolve...

well, it's "nice" to see im not the only one with the gpu problem around... i have a HP z820 with:
-2 Xeon e5-2640v2
-32gigs ram
-Cuadro k4000
-declink 4k BM display card
-cubix xpander with 3 titan black 8gigs each 18g total
-SSD OS win 10
-Davinci STUDIO

i've been working with no problems until davinci 14 with a lot of nodes in the projects NR included and never had this issue ... now im struggling every time i try to open one of those projects. ive done clean install, transcoded clips, the OS is perfect... the 3 titans never reach to work at 100% and suddenly i get the "your gpu memory is full" error

Did yiou tel resolve to ignore the quadro?

yep! just updated it in the other post viewtopic.php?f=21&t=80013&start=50

I had the same problem upgrading to v15. I have three nvidia 1080ti’s, 12gb a piece, in a Cubix Xpander. After I moved up resolve versions ‘gpu full’ was a constant on 5k red footage playing back in 4k timeline. My solution was to remove one of the gpu cards, leaving two in the xpander and the red rocket x in the pc. No more errors and playback was flawless whereas before having three cards slowed everything to much lower frame rates. I will continue to experiment.

Wondering if the new nvidia drivers helped as well. Saw a memory leak issue fixed mentioned on Windows somewhere...

Started using Linux for that reason lol

I've had this same experience with 2x 1080 Ti, removing one tends to make 4K timelines and heavy TNR more stable. Must be something with how memory is swapped between cards with limited VRAM?

We recently upgraded to a single RTX Titan as a test - it's not as fast as 2x 1080 Ti but it doesn't get the memory full errors and can deal with an absurd amount of TNR at 4K (10x 5 frame Better TNR on 8K R3Ds at Full Premium. Whyyy does it work?).

I understand memory limitations but I wish Resolve was a little more graceful handling these exceptions.

The new drivers didn’t help, seemingly as I was already using them when I upgraded to V15 of Resolve. The other issue, I suspect is the cooling of the Cubix Xpander. A bigger fan wouldn’t go amiss to ensure gpu stability.

Will have to look at the RTX Titans. Sound promising for a future gpu upgrade.

Radeon VII is only $700 and has the same or more speed than the $2500 RTX Titan.
The 16 GB is enough for doing 8k work (effects + TNR) atleast on our VEGA FE's.
Radeon VII is faster because of the memory bandwidth (1024 GByte/sec).

Some gamers will be happy to buy your old 1080ti's for a good price.

ps. Radeon VII can make use of the HBCC so you will never run out of memory.

I forced latest NVIDIA / ETC drivers onto my video card and it fixed it 100%

thanks
