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

[Zachs]

Did 3 not work as well? It is exactly the same as 2 only with more debug messages.

[Zachs]

OK guys, here's another OpenCL test app (http://www.zachsaw.com/downloads/mpdn_test/DxClTest4.zip).

Debug log now prints the extensions supported as well as the GPU name of your chosen adapterID.
More importantly, I've added Nvidia GPU support. Could you guys with Nvidia GPU (as well as the Optimus guys) give it a go and report back?
As before, I'm interested in min/max frame rate and your GPU model.

Oh and if you don't see flickering / flashing square then it isn't actually working.

Cheers!

Geforce 820M 56 FPS
Geforce 840M 66 FPS
Geforce 850M 109 FPS (updated to 350.05 driver and gained 3FPS)

Not much fluctuation in frame rates.

[Zachs]

Wow that's quite slow compared to even Intel GPUs.
These are Optimus systems right? What does GPU-Z say about GPU load?

[ryrynz]

Yup. 83 to 85% for both.

Surprisingly the 820M and the 840M have the exact same performance in this test. *edit* Was testing another 840M..

[Zachs]

Not very surprising if they both have the same amount of memory bandwidth :)

[ryrynz]

Actually tested another 840M (should've double checked) Same memory bandwidth as the 840M yeah, the 820M gets 56 FPS.

A few FPS seed boost using 350.05 drivers.

[Scyna]

394/404 i did DxClTest.exe 2. only 2 would work out of 0-4. the others would crash it. I had amd 290 and intel hd on here. I'm not sure how to tell which gpu ran that or how to see debug. nm my msi afterburner shows activity with the intel hd so i don't know how to get it to work with my amd.

[Anima123]

HD 4600: 194.xx fps

My laptop has Optimus and it seems unable to use the nVidia 880M on the test program, as GPU-Z indicated.


Edit: In the FineSharp thread, you mentioned:
Yes this change would be necessary for MPDN's UNORM (which is the default now) texture too.

Is that modification necessary? I didn't see corresponding changes made with render script.

[Zachs]

Ah I don't think you had it running on AMD at all then.

Can you try running the latest test app and run DebugView in the background?
When you run DxClTest.exe 0 (try all 0-4), it'll spit out debug messages in your DebugView window. The first line should say which adapter it is running on. When you find out which is the right AMD adapter ID, could you paste the log here for me?

[Zachs]

HD 4600: 194.xx fps

My laptop has Optimus and it seems unable to use the nVidia 880M on the test program, as GPU-Z indicated.

I think you have to set the app to use Optimus specifically in your Optimus tray icon.

[Anima123]

I think you have to set the app to use Optimus specifically in your Optimus tray icon.

I did set 3D settings in the nVidia Control panel, which didn't work. What's the Optimus tray icon?

Edit: From what GPU-Z told me, the test app uses nVidia 880M for a few seconds before it fall back to the HD 4600.

There's a tray icon that allows you to select which app to run in high performance mode - do you not have that?

[Scyna]

How do i see the DebugView window?

[Zachs]

In the FineSharp thread, you mentioned:

Yes, otherwise it will not work with MPDN's render quality set to Quality mode (High quality and performance modes are fine).

[Zachs]

How do i see the DebugView window?

Download it :)

There's a tray icon that allows you to select which app to run in high performance mode - do you not have that?

With my laptop, the only way to do that is through nVidia Settings.

[Zachs]

ok heres the log


What OS are you running?

[Scyna]

windows 8.1 64x

[ryrynz]

AMD M260 170 - 183 FPS

Nvidia 750 Ti 180 FPS, 70% GPU load, 47% Memory controller load.
Overclocking 200 MHz on the core and 250MHz on the memory only gained me 8 FPS.

[Zachs]

OK guys, here's a new tester (http://www.zachsaw.com/downloads/mpdn_test/DxClTest5.zip). It should improve Nvidia's framerate by quite a large margin (other GPUs should benefit as well) so please give it another try.

[Zachs]

ok heres the log

It appears that the AMD driver reported two platforms but neither will work with the Direct3D device. I'll try to figure out what is going on.

EDIT: Can you run the latest tester with DebugView again? I'd like to see what the new log says.

[ryrynz]

Nvidia 750 Ti 480 FPS default, 528 FPS overlocked. Quite the jump..

90% GPU load, 85% Memory controller load.

[nevcairiel]

1350 fps on my TITAN X, nice jump. ;)

That's really strange. The debug log doesn't even have the error messages I added for DxClTest5. I'll upload another one later to be sure.

[Zachs]

OK I've just uploaded DxClTest6.zip (http://zachsaw.com/downloads/mpdn_test/DxClTest6.zip). Can you give that a try on the AMD?

EDIT: Can you also give DxClTest7 (http://zachsaw.com/downloads/mpdn_test/DxClTest7.zip) a try? (I don't have an AMD card capable of OpenCL with that extension so it's a little hard for me to work out what is wrong)

Hmm for some reason the AMD driver doesn't match the OpenCL platform with the Direct3D device even though it's been created on that GPU. I'll see if I can get my 4350 to work.

[Zachs]

Just to confirm, does it work when you choose the Intel adapter?

EDIT:
Looking back at your posts, I think you're using DxClTest.exe incorrectly.

If you have two GPUs on your system (AMD and Intel) where AMD is your primary, you should run
DxClTest.exe 0

You can then test it out on your Intel GPU by running
DxClTest.exe 1

Unless you have 6 GPUs on your system, you can't run DxClTest.exe 5.
When I said Test5, I meant DxClTest5.zip, not running it with an argument of 5.

[huhn]

when i connect my intel yes.

http://forum.doom9.org/showpost.php?p=1716773&postcount=1650

the intel is just running in headless mode.

i just connected my intel and run version 7: it is slower with ~256-275 FPS.

madshi openCLspeedtest tool works totally fine on my AMD and Intel. so openCL should work in general and the same dx9 <-> openCL interop is mostly likely tested.

[Zachs]

Direct3D is reporting gibberish as your Intel GPU adapter name (e.g. mine says Intel HD Graphics)...

[Zachs]

tested 0-5
all report invalid adapter except 0 which should be the intel.

Is this with your AMD card in the system or not?
There's something fundamentally wrong if Direct3D can only detect one adapter if you have both the AMD and Intel GPUs enabled.

EDIT: Anyone else with a discrete AMD card tried the app?

this is with 1 which should be the AMD.

0 reports the AMD when the AMD is connected and 0 reports the intel when the intel is connected

maybe they changed something in my windows 10 build. but the nvidia PC is running windows 10 to and it works with "1" perfectly. and other things like madVR nnedi3 and the test tool is working fine...

[Zachs]

I'm not sure I understand what you're saying - if you have just the Intel active, then yes 0 should be Intel. In that scenario, does the app work at all?
When the AMD is connected, but with Intel disabled, can you get the app to run (0 is the AMD in this case)?

ryrynz managed to run the test app with AMD mobile GPUs though, so I'm not sure what the problem is. Anyway, could you isolate the problem by running just the AMD card and see if it works at all?

my PC has 2 GPUs the intel HD4400 and the AMD r9 270.
when i simply connect the intel it works by using your tool with 0 the intel is reported and the test starts.
when i connect the AMD and run your tool using 0 it reports my AMD as the d3d device and your tool doesn't work with 0 and 1-5+ just crash.


even when the intel is disabled in the device manager it is reported as platform 0 and the AMD as platform 1

the last thing i can do is disabling the intel again (i'm not even sure if i can disable the GPU completly) in the bios and try it again but this didn't work in the past.

i never actively used both GPUs at the same time.
are you using windows 8 or newer they added GPU headless mode for these version maybe there is the problem.

i "disabled" the intel iGPU in the bios and i check the device manager. the intel wasn't listed.

but when i run your tool i get the same error:

and the intel is still listed as platform 0...

here even a screen: http://abload.de/img/testsyj7m.png

Thanks for testing huhn!
I think the Intel platform will always be there because your Intel CPU supports OpenCL as well.

I'll check my code to see if there's anything wrong with it. This is different from the Nvidia + Intel case as only one platform has cl_khr_dx9_media_sharing.

OK last attempt to test my hypothesis before I call it a night - DxClTest9.zip (http://zachsaw.com/downloads/mpdn_test/DxClTest9.zip) initializes in the reverse order so it should pick up the AMD one first.
