Media Player .NET (MPDN) - D3D HQ GPU Video Renderer [v2.49.0/v1.31.0 27 Dec 2018] - Page 237

NVIDIA never cared about OpenCL, and they are certainly not going to start now, especially since OpenCL is basically deprecated in favor of Vulkan Compute Shaders - which support FP16 on NVIDIA.
Honestly, any new code in OpenCL is probably a mistake, and you should look into Vulkan instead, which actually has a pretty wide support base on Windows already.

PS 3.0 it is then.

Zachs · 1st March 2019, 10:08

Finally managed to optimise it enough to run at 13ms to do a 2x upscale of DVD res. 1080p to 4k is out for GTX 970 at 67ms but any recent cards like GTX 1070 should do just fine.

Big thanks to Shiandow for his valuable insights!
Now we just need to port it to MPDN renderscript.

Zachs · 12th March 2019, 14:51

Created an extreme quality version for 3x upscale (most likely will require 2080ti and above to do 720p to 4k uspcale).

Normal quality version will run real time without a problem for for 720p to 4k upscale even on my old 970.

foozoor · 12th March 2019, 17:38

No normal quality screen to compare?

Zachs · 12th March 2019, 22:52

Normal quality is not nearly as good but for other images it's not as pronounced as this one. This one has lots of high frequency components.

ryrynz · 12th March 2019, 22:56

The first thing that stands out to me with this upscale is the strength of the darkening of the lines creating an almost cartoonish appearance, can that be reigned in a little?

Zachs · 12th March 2019, 22:56

That said however, it still fared very well against other state of the art scalers.

That's how the original image looks like. You can artificially blur it though but that would drop SSIM significantly vs ground truth.

After many rounds of optimisations, 1080p to 2160p only needs 18ms on my GTX 970!

720p to 1440p is 9ms.

3x from 720p to 2160p is 35ms.

Zachs · 14th March 2019, 14:27

3x upscale sample (720p to 2160p):

any ETA when user will get there and on it?

it's easier to find issues with the scaler this way and if proper way to reproduce are given to you you maybe able to improve on it.

Zachs · 14th March 2019, 22:57

This will be the baseline model. Any improvements will be looked at after we get this one done.

Anima123 · 10th April 2019, 00:59

Zachs, how's it going on with incorporating your new scaling into MPDN? I'm asking since it's been a while, and am still looking forward to it.

Was too busy with work lately to work on it. Will try to continue when I get some spare time. It just needs to be written as a renderscript.

louiebh · 20th May 2019, 10:35

whats the latest version and where can we download it because your personal website is down!
im happy this project isnt folded up yet!

Could i also get help with the Reclock script? mine is basically saying "Audioscript could not initialize" and the in brackets (AMD/Intel OpenCL drivers unavailable)?

Zachs · 23rd May 2019, 01:04

I've hosted it on AWS S3. The latest is on the OP. I've had no time to maintain a website so I've shut it down.

You'll need to read OP to setup OpenCL drivers so you can use audio scripts.

dave_in_gva · 31st May 2019, 15:12

Zach,

Can you unpack some of your acronyms above? What is the URL for downloading the latest installer? I'm afraid it is not clear to me what you mean by:

"I've hosted it on AWS S3. The latest is on the OP."

I've been using MPDN for 3+ years and love it. My laptop died and I am setting things up on a new one and have been getting error messages with my original installer.

Thankyou if you can steer me to the latest build.

Best wishes,

Dave M
