CUDASynth

These CUDA filters are packaged into DGDecodeNV, which is part of DGDecNV.

Will do. IIRC I have an 800W supply in there. I'm going to install tomorrow morning.

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.

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. :wow:

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.

Christmas came early. ;)

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

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.

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.

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

I've just seen this: https://github.com/nekopanda/AviSynthPl ... isynth-Neo.

What do you think about it?

I can't read Japanese so can't make much out of it.
