Premiere Pro 25.1 - iGPU stopped decoding my footage

[AndrewTheGreat]

Ok, just updated to v 25.1 opened my projects in progress to find out that none of them uses my iGPU to decode.

Went on checking it with different formats that are decoded (h264 8-bit 4:2:0, h265 8-bit 4:2:0, h265 10-bit 4:2:0, h265 10-bit 4:2:2) by the iGPU - all of them show 0% load.

What is going on, guys? Why is it "new version - new bugs" thing every time? My CPU immediately started being loaded more, like by 60% all the time, even though my GPU does the decoding, whereas on the previous versions the average CPU load was 20-30% with the iGPU doing all the decoding job.

Yes, I tried reinstalling both Premiere Pro (as well as resetting its cache, preferences and plugins via the start+shift menu) and all the drivers. 

Steps to reproduce? Open a project or create one, import a knowingly decoded video, put it on your timeline, press Play. Watch the the Windows Task manager - Performance graphs.

A couple people were able to go into their BIOS for their motherboard, and found that build of Win11 had turned off iGPU usage. They turned it back on in the BIOS, and all was well. 

A couple other posts I've seen elsewhere were frustrated because they did that, but on rebooting the machine, Windows turned it off.

AGAIN.

That's very frustrating to hear.

[AndrewTheGreat]

Hi @R Neil Haugen 

Do you happen to know if the iGPU in those cases was completely turned off? Because in all my cases I can always see it in the Device Manager and in the Task Manager > Performance though the behavior is as described above. As if only the video engine does not start

[AndrewTheGreat]

Another update. Don't know if it's related or not. Here's a screenshot of Premiere Pro doing the transcription via the iGPU. And it's not a video it's decoding. It's a wave-file. There's no video in the project at all.

I have similar problems. Decoding on UHD only works for H.265. For H.264 it does not work on UHD, but it works on NVIDIA. If you disable decoding on NVIDIA in Premiere Pro settings, decoding on UHD for H.264 starts working, but does not work for H.265.

My PC:
CPU-12600K
GPU-1080 TI
RAM - 32GB DDR4 3200

Driver UHD - 32.0.101.6314
Today I tried the new driver 6325, decoding did not work on it at all.
NVIDIA driver - current studio

[R Neil Haugen]

Crucial data left out: which Windows build are you on?

[Raman275720276xpc]

Windows 23H2, 22631.4541
It all started with an update of Premiere Pro from version 25.0 to 25.1. At the same time, other components of system did not change.

[R Neil Haugen]

See the post below yours from Jonesvid.

[Raman275720276xpc]

Returned to Premiere Pro 25.0, here decoding works again.

Latest official statement received from ASUS today after I raised this iGPU/dGPU problem with them as an ASUS motherboard user.

Unfortunately at the moment there are no updates on this problem. We and Microsoft are working on a resolution for this issue and it will be provide with a further update when available. Please note that we share the same resources on all levels of support so even if you get in touch with Level 2 you will receive the same answer. Once a fix for this will be available a notice will be posted on the Microsoft website and a new update implemented. 

https://learn.microsoft.com/en-us/windows/release-health/status-windows-11-24h2

For the moment the most reported chipset was Z890 but as it is a problem coming from an Windows Update it is not limited just that. Other products motherboard, laptops, desktop, can encounter the problem as well.

So I will kindly ask you to wait for a newer update for the Windows 11 24h2.

I was hours away from wiping the W10 PC (after disk Image saved on external back up disk) )  to load a new W11 24H2 install when I came across this post. I have since stopped all actions to do this until 2025 when we hopefully get some fixes.

To complicate matters further, it would also appear you cannot go back to a previous W11 23H2 fresh installation with ISO image or Media Creator Tool as Microsoft in their wisdom have removed access to these on Windows 11 downloads.  .......Great.

Take note.

Any more news for us @mayjain  ?

[nathaliedevent]

I'm also having this exact same issue. Used to work before.

When I'm rendering, scrubbing, playing or encoding h.264 (or any other codec), the iGPU stays at 0% during the process. My playback is severely lagging and stuttering.

All drivers are up to date, Windows 11 Version 23H2 for x64-based Systems (KB5043076), entire creative suite is up to date, BIOS has been flashed and the iGPU is enabled in the BIOS, yet the iGPU is not utilized during any work in Premiere Pro.

This is an i9 14900k on a MSI Z790 Tomahawk Max Wifi.

Again, this used to work fine a few months ago.

[JonesVid]

See my posts below.

Premiere Pro 25.1 seems to treat H264 differently for decoding (even on Win 11 23H2) - so discrete GPU is used and not the iGPU on motherboard.

You can go back to 25.0 which is what I am going to do until Adobe come back with some sensible statement on this issue - which we are still waiting on @mayjain 

[RjL190365]

Further testing with my main system with Premiere Pro 25.1 on Windows 11 24H2 with actual H.264 and actual HEVC footage confirmed my earlier suspicions: With both the iGPU enabled and with a discrete RTX 4070 Ti installed, the iGPU did function with HEVC but not H.264. All H.264 decoding got sent to the dGPU.

And the lack of activity on the "Video decoding" portion of the iGPU graph for HEVC does not mean that the decoding is broken per se, but rather a bug with the reporting in the Windows' Task Manager itself. The "video decoding" part of the graph only works properly when the iGPU processes everything while the dGPU sits idle or is disabled.

[JonesVid]

I have also conducted similar tests on H264 and H265 decoding but on Win 23H2 as I have stuck with that for now.

I can confirm I get similar results on PPro 25.1 with H264 decoding not active on iGPU. All load spread accross Nvidia RTX 4080 Super and CPU (13900K).

We are dealing with several variables here as we know there are issues on Win 24H2 as seen in many articles and statements from companies like ASUS.

I have also seen this Oct 24 article on Tom's hardware - https://www.tomshardware.com/pc-components/cpus/z890-motherboards-are-having-instability-issues-with...

This however,  talks about the later generation Ultra CPU's, but not sure it is limited to that if you are using a newer driver.

I might try my older ASUS iGPU driver to see if that changes things, as per @AndrewTheGreat tests.

A bit more research on Microsoft blog reveals a lot going on with iGPU reporting and its use - dependent on many factors.

Ref article - https://devblogs.microsoft.com/directx/gpus-in-the-task-manager/

This is an old article and Task Manager with these capabilities were introduced in Windows 10 so who knows what might have been upset in Win 11 24H2 if Microsoft have reworked some graphics code in that new release.

I will need to read this a few times to get my head around it 🙂

Regardless of all that,  it would be useful to know what Adobe have done in version 25.1 which makes it behave differently for H264 decoding, as this has introduced a change, even on Win 11 23H2.

Unless you are looking at task manager you may not even notice any difference in performance if you are using a fairly good dGPU as that is taking additional load with the CPU.

If you platform is older it may have more impact where it relies on the iGPU.

We await more news.

[JonesVid]

My final post on this until we get more information from Adobe.

Have just gone back to Premiere 25.0 and with Win 11 23H2 this does decode H264 on the iGPU. Behaviour is the same as decoding a H265 clip.

So if we isolate Win 11 24H2 issues at present, looking at Premiere 25.1 release, it has different behaviour handling decode of H264 clips - i.e: it does not use iGPU.

As requested Adobe team please give us an explanation - still silence from Dev team on this??

Also - what does your text advertising Premiere 25.1 mean, I quote " faster H64 performance ...." see attached picture snip

I would say the complete opposite quite frankly.

[R Neil Haugen]

The faster H.264 performance was clearly tested on a bunch of machines, noted in the public beta testing, and several of the people on this and other forums have posted notable improvements on their rigs.

The specific issue you're hitting in this, which is hitting a relatively small subset, is a nasty little bugger and I'm grateful for the testing you've done ... and posting the results.

@Mayjain  ... comment?

[максимр49812736]

I confirm the problem. Initially, on a freshly installed Windows 11 24H2 Premiere Pro 25.0 used iGPU decoding instead of dGPU. After updating to 25.1, decoding occurs on dGPU. When turning off Nvidia decoding in the settings, it decodes on iGPU. Config is Intel i5 9300h with Intel UHD 630 Graphics, Nvidia Quadro P620 (Dell Precision 3541 Laptop, latest BIOS). So, it's only Premiere's problem.

[shellkursk]

I have exactly the same story.

Both video devices are enabled in the decoding settings, but ONLY discrete nvidia is working on decoding.

Win - 24H2

intel driver - 32.0.101.6332

Adobe Premier 25.1

Turned off nvidia decoding resolution in the media settings, only then did intel start decoding.

[Nubooo]

Hello, so ive been having a similar issue, had to install windows again because my drive died and now on the new premiere the IGPU wasnt working,

I have enabled hevc decoding on intel only (nvidia unchecked)

I have enabled hardware encoding

this has resolved my issue and now both nvida and intel using about 30% effort when i playback, my theory is nvidia have already enabled or forced the Nvidia card to stay on in the background anyway so we need to only enable the intel, ofcourse that is just a theory but worked for me

using rtx4070 and 13700k

[JonesVid]

For H265 HEVC Codec both Intel iGPU and NVidia GPU can be seen to decode in Windows Task Mgr

For H264 only NVidia GPU can be seen to decode.

It is H264 footage that iGPU does not decode anymore on Premiere 25.1. Turning off NVidia GPU will then force iGPU to decode H264 but this defeats the object of having two GPU resources to share decode/encode.

You only only mention HEVC H265 codec ?

[JonesVid]

On Premiere Pro 25.0 this decoded H265 and H264 on timeline during an encode export process to another codec (such as exporting to ProRes as a test) using split with iGPU and discrete (Nvidia) GPU. This is correct.

On Premiere Pro 25.1 and also on the latest 25.2 beta Build 58  this does not happem and it is ignoring the iGPU resource entirely for H264 hardware decoding Media

This is a bug that has been introduced after Premiere 25.0 version

[jamieclarke]

Hi @JonesVid - I do not see this issue in Premiere Pro 25.1 or beta 25.2.  We need a few more details to try to help with the issue. Can you post a screen recording of the issue you are seeing.  Can you post a screenshot of your media file properties.  What GPU are you using and which driver?

[JonesVid]

I suggest you also refer to the thread below which has lots of documented info on this problem

The thread was started by @AndrewTheGreat 

At first we thought this was just down to the anomalies of Win 11 24H2 - BUT - I decided to stick on Win 11 23H2 and the same thing happens on that version with Premiere 25.1.

Intel iGPU is not used for H264 hardware decoding when using 25.1. Only H265 decodes

However, using Premiere 25.0 both H265 and H264 can be decoded by the iGPU and shared with the NVidia GPU

I am using 4080 Super GPU and driver is 566.14

The iGPU is using 32.0.101.6314

Win 11 23H2 version latest updates .

I have halted any upgrade to Win 11 24H2 at present as that can introduce other problems with some Intel chipsets

Please read through this

https://community.adobe.com/t5/premiere-pro-discussions/premiere-pro-25-1-igpu-stopped-decoding-my-f...

I did a test with the same clip on the timeline - one H265 one H264

The sequence was set to ProRes 422

I output the export as ProRes 422

Looking at the windows task manager you can see activity for iGPU on the H265 decode, Nvidia encoding load and some CPU load

When it gets to the H264 clip - iGPU goes silent and all load is taken by NVidia GPU and CPU

This is using Windows Task Mgr / Performance graphs - see also in the above discussion thread.

I tried Beta 25.2 build 58 and this version does the same.

What is your test setup? @jamieclarke 

[MyerPj]

One thing I did a few weeks ago, and it made my motherboard Intel kick in to help was to deselect Nvidia in Prefs/Media.

I didn't test it further, but would be interested if you did! 🙂

[jamieclarke]

Hi @JonesVid -  Andrewthegreat has a highly customized setup and has chosen not to provide details about some of the modifications to his motherboard. As a result, it might be best to approach his input with some caution.

 I tested an HEVC 10bit 420 and h264 8 bit 420 and they both use the igpu and discrete gpu for playing back and exporting in 25.1 These are my specs 

SYSTEM SPECS:

13th Gen i7-13800H 2.5Ghz

64GB Ram

Windows 11 Enterprise 23H2  

iGPU Intel Iris Xe 32.0.1.6078

NVIDIA RTX 4080 GPU Driver: 566.14

Would you be able to send me a project and test files so that we can take a look?  please send them to jamiec@adobe.com Please provide your steps for reproducing your issue.  Please proivde a screenshot of your export settings.  Just to confirm you are saying that you don't see any percentage in task manager under your igpu?

We also need to know the media type you are working with not all h264/hevc types are hardware accelerated.

[JonesVid]

Thanks - Hang on though - we have been testing on i9  13900K CPUs and i9 14900K CPU's.

I don't know if the onboard iGPU is seen as identical to your 13800H CPU for these tests ???

We are also not Windows 11 Enterprise version.

We are on standard Win 11 23H2 Pro (myself)  and Win 2411 H2 Pro for AndrewTheGreat

Are you on a laptop?

I will take more screen shots on my test tomorrow and post them here as getting late here now

This definitely shows iGPU idle for H264 footage

In other people's tests - they have reported same problem on Premiere Pro 25.1

My setup

Z690A ASUS motherboard

System NVMe 2TB

Projects NVMe 1TB

Export Drive and Media Cache NVMe 2TB

Media Drive 2TB SATA

RAM 128GB Vengeance

CPU Intel 13900K

GPU Nvidia 4080 Super

@MyerPjthanks for your note - this would imply that the 'intelligence' to use both iGPU and NVidia GPU is lost on 25.1. It has to be told not to use NVidia and only use iGPU
