most browser video renderer today can't deal with windows scaling and they do everything as fast as possible.

i still think think pathetic is a good word for the default web browser renderer.
and it is pretty obvious what a web browser renderer is doing to get the lowest possible Vram usages it's not like EVR is wasteful or something like that.

mpc-hc may not support it but jriver say they support it: https://www.jriver.com/video.html
i don't know how it works in jriver.

It looks like GT 1030 has a different (slower) Video Decoder than the rest of the Pascal family.

Tested in Linux and H.264 - 720p/1080p, it looks like having a GTX 950 video decoder.

Unless that test is not about pure decoding, but rather playback performance, so the weak GPU shrinks the pure video decoder's performance.

Might be limited by its low memory bandwidth, doubtful they would put an older chip in there - but someone with DXVAChecker could figure that out.

After Windows Creators Update, the old Chrome trick via the --enable switch to force enable VP9 hardware acceleration on Polaris RX 400/500 cards doesn't properly work.

Does anyone have any idea how to enable the VP9 acceleration of Chrome/YouTube on Polaris cards ?

I want access to VP9 4K60fps content, so no other browser is suitable for that.

Seems to work in Edge on my GTX 1060. Tested up to 8k VP9 w/ 10% CPU usage and no dropped frames. Chrome can't even do this, actually, at least not on my system. Same video pegs my CPU and drops frames like crazy.

[NikosD]

Nvidia is different and it has a pure video VP9 decoder.

And I don't think Edge can access all YouTube streams.

Some of them, like 4K60fps are VP9 only and Chrome only (I think)

[sneaker_ger]

Edge has VP9 but I don't know if it's compatible with AMD.

[NikosD]

Besides Chrome-only streams of YouTube, I want to avoid Edge for one more reason.

I haven't found out yet a way to move Edge's cache from my SSD (C to HDD (D

Is it possible ?

According to "Stats for Nerds", all the streams I tried were VP9.

[P.J]

Wonder why youtube used H.264 for 8K

[huhn]

it's VP9 too...

The new Windows 10 Insider Preview Build 16226 adds a GPU utilization Tab in Windows 10 task manager.
The Performance tab shows GPU utilization information for each separate GPU component (such as 3D and Video encode/decode), as well as graphics memory usage stats.

The Details tab shows you GPU utilization info for each process.
Please note that this feature is still under construction and you will find issues and bugs.

Hello, this is my first post here on Doom9. I just purchased a
gt 1030 for the ancient 8 yr old Intel icore duo at work, just
to benchmark this board representing the least expensive nvidia
solution for HEVC decoding. My PC (Dell Dimension 780) is a
stand-in for the millions of old systems that now cannot decode
HEVC.


Benchmarks: Nvidia Gt 1030 @1227Mhz/Intel E8400 2core3.0Ghz
LAV 0.70.0 DXVA Checker 3.15.3 Nvidia driver 382.53

About the choice of benchmark clips:

Although NikosD's choice of clips are illuminating, I feel
they don't represent the real-world videos and movies
that people are actually going to view. "Lovely Swiss", for
example, while very pretty to watch, is really just a slideshow
of individual images with virtually no movement or panning at all,
making it a perfect foil for interframe compression. Almost all
real video/film content, on the other hand, is basically all
movement, due both to camera and subject.

Thus, I included some clips (all easily available on the web) that
I think are more representative of content that people will
actually be exposed to now and in the future. "Exodus" and
"Life of Pi" Trailers represent professionally directed and encoded
UHD HDR 24fps content, and "Colors of Journey" and "Sony Camp" are
4K 60fps video that represent non-movie but again professionally directed
and encoded 10 bit content. "Tears of Steel" is an interesting
8-bit professional 4K short movie.


Observations:

The GT 1030 can play all of the videos above perfectly and with only
about 20% CPU utilization on an ancient 8 year old 2 core 3Ghz
wolfdale PC. This lowest-end (so far) Pascal GPU furthermore
has the lowest TDP in the 10x series, which means that no old
PC system has to worry that their old power supply can support the
graphics card. The 2 GB video memory seems perfectly adequate to play
the most demanding 4k videos, while *simultaneously* downscaling to
whatever resolution the current PC monitor has. This seems to me
to demonstrate that this GPU is ideally suited to the millions of old
PC systems, and all of the HTPC systems, that would like to upgrade
their systems to allow playback of what I think will be the universal
video encoding standard. Unlike some other posters in this forum, I
would heartily recommend this GPU. At $69 (ZOTAC GT 1030) I don't
think the card has any drawbacks at all.

Plus, now even Google Earth can draw its' 3D buildings and terrain
on my old system with some alacrity.

I have nothing to do with Nvidia or Zotac, I'm just reporting
benchmarks and observations.

Very interesting first post

We usually post both pure decode benchmark and playback benchmarks down scaled to 1280x720.

Also, can you post your DXVA Checker screenshot ?

It would also be useful to post your video clock not GPU clock during playback benchmarking.

What is your OS ?

But benchmarks on DXVA Checker don't guaranty smooth play back with common apps like madVR in reality, especially by HDR output.

Two more favors:

1) I don't see any 8K clips - 8bit or 10bit

Can you test some 8K clips from my samples collection ?

2) If you have a fast Internet line (e.g VDSL) can you test Youtube 4K60fps VP9 clips using Chrome ?

I would like you to test them in a standard Chrome window-mode (not full screen) and see the stats for any frame drop.

thanks!

I am currently under 1030 driver level 382.53, but will install the latest version later. Here is the current DXVA checker screen (see attachment).

NikosD, I did test the arri 7K clip, as it could be downloaded quickly, but the others are very large and the servers refused fast downloading. The "girls" video takes a long time to benchmark and this cannot be done at work

I am able to view 8k chrome you tube videos (from forum discussion here last month) but the actual bit rate is too high for the internet connection here at work. Post a link to your 4k VP9 videos and I'll try to view them.

[edwdevel]

Oh- I am under Windows 7 SP1.

Also, I don't know how to the "video" clock as opposed to the graphics clock for the GT 1030. Is this part of DXVA checker?

You have to use a tool called HWiNFO and look for "GPU Video Clock" in the monitoring parameters.

For VP9 4K60fps content in YouTube, just run Chrome and put in the search field of YouTube "4K60" and you will see a list of 4K60FPS videos.

It doesn't really matter which one you choose.

Just see the CPU usage while playing and frame drop in "Stats for nerds" (right click on the clip)

It will also say if the clip is 60fps and in VP9 format

The image of DXVA Checker is not visible.
The best way is to copy paste a direct URL of some free "upload image" service using the insert image button of Doom9.

@edwdevel
Use external photohostings. For example: sendpic.org, jpegshare.net.

Please test Sony_4K_HDR_Camp.mp4 in MPC-BE and make a screenshot with statistics enabled (Ctrl+J) after 15 or more seconds of playback (so that the chip's frequency is stabilized).
