Re: CUDASynth
My 2080 Ti shipped today and will arrive Saturday.
Re: CUDASynth
Financed by my users. Thank you!
Re: CUDASynth
I stepped out for an unavoidable coaching session, and 7 minutes after I drove away the FedEx guy arrived. Murphy's Law. They retry tomorrow and I'll be home all day. I am excited about the tensor cores.
Re: CUDASynth
Bogus info from the lady on the phone! Won't be re-attempted until Tuesday and cannot pickup at FedEx facility per nVidia instructions.
Re: CUDASynth
Gotta be patient, I guess
Re: CUDASynth
Oy, Fedex! So after telling me the delivery would be Tuesday, they came today (Monday) and of course I was away again. Now the website says they are holding it for pickup at an office 15 miles away! I'll drive out there to pick it up and I suppose they will say it is on the truck for delivery.
Re: CUDASynth
Alright, the beast is sitting on the desk in front of me now. All's well that ends well. Building up the courage to do the install...
Re: CUDASynth
Watch the power requirements, RTX might be a little higher than the GTX
The RTX has been measured at close to 280 watts

Re: CUDASynth
Will do. IIRC I have an 800W supply in there. I'm going to install tomorrow morning.
Re: CUDASynth
LOL, it's 850W.
The 2080 Ti install went smoothly. DG tools still working fine. The List GPU dialog shows some weird things, like 0 CUDA cores. I'll have to investigate that. Maybe things need to be rebuilt with a later CUDA toolkit. Will get some preliminary performance numbers shortly.

Re: CUDASynth
Testing 3840x2160 HDR -> SDR script with pipeline:
1080 Ti runs at 180 fps.
2080 Ti runs at 321 fps. 338 fps with moderate overclocking.
That is a hefty performance boost.
It seems they did some great work on the video engine.
Now I have to decide whether to keep the 1080 TI in this machine as well, or upgrade my backup PC. Putting it in this machine will allow more fun things to play with, such as encoding on the second card, etc.

Re: CUDASynth
Could you check the encoding features for HEVC (such as B frames) on the RTX 2080ti, please?
And you are right, those are some significant numbers on the fps
Question
If you did keep the GTX 1080ti and the RTX 2080ti in the same system which one would you use for frame serving and which one for encoding

Re: CUDASynth
I'll look into encoding. I never worked with it but this is a good time to start.
If I keep them both in I can try it both ways for decoding and encoding.

Re: CUDASynth
After further testing it appears that the large gain is due to the very fast memory on the 2080 Ti and not due to the video engine. The large gain is seen only for the pipeline and not when the frames are always transferred back to the CPU. So the faster memory copies to/from the GPU pipeline buffers must be the relevant factor.
Re: CUDASynth
Some new info, for me anyways, on the RTX 2080ti's capabilities
https://developer.nvidia.com/video-enco ... ort-matrix
Please note the new capabilities in the Decode section
Will require a new SDK which hasn't been released yet

Interesting, thanks for the link!
Avisynth Neo
I've just seen this: https://github.com/nekopanda/AviSynthPl ... isynth-Neo.
What do you think about it?

Re: CUDASynth
I can't read Japanese so can't make much out of it.
Re: CUDASynth
OK, but what does "with CUDA support" actually mean?
Re: CUDASynth
OK, now I'm an old guy who is officially lost and asking for directions.
I'm looking for latest CUDAsynth downloads and I guess AvsCompat.dll as well, per these,
viewtopic.php?f=14&t=506&p=9119&hilit=AvsCompat#p9119
viewtopic.php?f=14&t=671&hilit=AvsCompat&start=60#p9016
http://rationalqm.us/misc/CUDASynth_0.2.rar
which had it's own (older?) DLL versions
DGDecodeNV
DGHDRtoSDR
DGPQtoHLG
DGSharpen
Other downloads ?which seem to not be "CUDASynth enabled"? include
dgdecnv2053.zip
http://rationalqm.us/hdr/DGHDRtoSDR_1.11.rar
http://rationalqm.us/misc/DGPQtoHLG_1.0.rar
Hence, may I enquire about the latest status and plans ?

This is the latest stuff I could find from circa 9/10/2018:admin wrote: ↑Wed Oct 17, 2018 4:43 pmMeanwhile, on the CUDASynth front, I have discovered some very interesting things focused around what Prefetch() does in Avisynth+, and what the PREFETCH macro does in Vapoursynth, and how they interact with CUDASynth. It opens a possible avenue for further performance gains. I'll write a post about it when I get an energy burst.
A (vapoursynth) patch would likely not be accepted as similar ideas have been rejected. No problem; it's easy to replace AvisynthCompat.dll.

I really do like it here.
Re: CUDASynth
Thank you for your interest. I'll come back to this after dealing with a couple issues I have in DGDecNV.
Re: CUDASynth
Sounds like a plan, first things first.
Like, I thought I'd retired but now I'm back at work for a while ... one does what one has to
