But ONLY from Nvidia. No Nvidia? No CUDA.

[videoh]

Stupid post of the day. So what? No Microsoft no Windows. No Apple no iPhone. You get the drift.

[wonkey_monkey]

No, I don't get the drift, so maybe you didn't get the drift in the first place. If a user doesn't have Nvidia hardware then they're not going to be able to use anything that relies on CUDA. OpenCL, if I understand correctly is practically ubiquitous.

Then much better Vulkan than OpenCL.

Eheheh... Doom9, where impossible things happen.
(Honestly, though, I hope all the cuda core in my Quadro P4000 are fine xD)

True. Although OpenCL is available on any GPU, including those from Intel and AMD, it's also true that the performances have not been so good. Honestly, I don't mind pushing towards cuda. The whole industry is already pushing towards it and it's the de facto standard for those kind of calculations.

The thing is that OpenCL has been proven to be slow, especially on Nvidia cards, so losing a lot in performance only to make it run on different cards isn't generally something that businesses are willing to accept. I work in broadcast and I can tell you that no matter where you go, if you open up the workstations of any studio, you'll find an NVIDIA Quadro, it's just the way it is. Some very small studios may have an RTX but that's about it, it's always NVIDIA. What I'd like to see in the future for Avisynth is a widespread use of cuda with plugins that can work on the CPU for the rest of the community and on the GPU for those owning an NVIDIA card. I know it may not make some users happy, but industry-wise it makes a lot of sense. I work in the encoding department, we have servers running Avisynth automated tasks all the time for ingest and outgest (incoming and outgoing media) and I have plenty of NVIDIA Quadro cards that are used by AVID Media Composer and Davinci Resolve, but I can't use them for Avisynth (except for a very limited set of plugins - Thank you Donald ) and I can't use them in encoding either due to the lower quality outcome compared to x264/x265. I am actually using them to encode with x264 + OpenCL but honestly, the speedup is so reduced that I can barely tell the difference. I would love to be able to use them for Avisynth as it would speed up things a lot!

Same can be said about iPhones and lots of other things. So what?

It's like a joke from our youth: Why did the man jump out of the airplane? Answer: Because if he didn't jump out of the airplane he'd still be in the airplane.

You are saying nothing. Putting stuff in bold doesn't improve an argument.

So look at all the work pinterf and others have done to NOT keep Avisynth tied to a particular operating system. I just wondered if it might be preferable not to throw in with another proprietary system when there are open alternatives, but I appreciate that pinterf isn't starting something new from scratch here, if he's even starting anything at all.

maybe both or all (with Vulkan) since Vulkan not work with many old gpus but OpenCL do

like this plugin do https://github.com/HomeOfVapourSynth...h-Waifu2x-w2xc (it even work with CPU only)

gpu: Controls the environment to use.

    0 = disable GPU
    1 = auto detect. It will run on the first available environment in the following order:
        CUDA
        Vulkan 
        AMD OpenCL
        FMA
        AVX
        Intel OpenCL
        SSE3
        OpenCV filter2D
    2 = force to use OpenCL

Note that he puts CUDA first.

it's self-evident that CUDA is better for Nvidia

[videoh]

Y'all can only make self-evident observations? Or maybe it was a lame joke?

[DJATOM]

I love CUDA. Literally I'm NVidia fanboy, I think their GPUs are great

True NVIDIA fanboy would buy rtx3090 instead of that rtx2070 you have now. You must upgrade NOW!!!! Sell your kidney or/and car if you can't afford IT.

[DJATOM]

No, I'm not that insane. But I'll definitely buy 3080 once prices dumps.

They will dump maybe after 4000 series... But then 3080 will be outdated and new series will be again sold out directly to chinese crazy miners.

Wait for TI flavor. If you want to work seriously with 4K HDR, I think you will need more than 10GB for heavy MT.

I ain't a programmer but I can see FFMPEG is following the Vulkan path for general compatibility. And, to be honest, lot of not so ancient hardware supports it.

[videoh]

I would buy three 3090s right now if I could find any.

[DJATOM]

> TI
I'll consider it based on my local prices and availability. Literally I need it for filters like eedi3/nnedi3 where 10G memory isn't really a problem. In fact, 2070 with 8G is enough for it, but eedi3 is slow.
