GPU Hardware Acceleration not enabled

I have a 3080TI and Adobe Media Encoder/Adobe Premier are not using it to render even if Hardware accelaration is enabled. Its a major problem, cause i'm sure rendering with it will be 100% faster than with the cpu (9900k)

Hello, most reports these last days are about problems with the most recent nVidia drivers.

https://community.adobe.com/t5/premiere-pro-discussions/premiere-pro-community-digest-november-2022/...

 

  • NVIDIA GPU Drivers causing hangs on import and unexpected behavior: Some editors have reported problems with the NVIDIA Studio Drivers v.526.98. Roll back the drivers to v.522.xx or earlier to restore system stability.

I think it goes beyond just drivers. I would really like this fixed because it means an extreme amount of time is lost because of the lack of interaction between the GPU/CPU and software. 

I just updated to 527.37 / clean install, restarted pc ... still nothing. The renderer prioritises the CPU instead of the GPU even though its set to use the hardware renderer

Do a clean installation of the 517.40 Studio Driver (NOT the Game Driver)

Ok, I just did that, 517.40, manually downloaded, clean install, restarted pc, ran through Media Encoder a test file for rendering... nothing changed. CPU is still being prioritised over the GPU

Yes, the rending i'm doing has a massive moving gaussian blur, color changes, 3d particles. 

I've tried to also install the CUDA Toolkit and there is no change either. CPU usage 90+% while the GPU sits under 5%, probably other stuff i'm viewing on browsers and stuff. Under task manager, the GPU has 0% registered "video encoding" activity

Still images create a special problem. If any of those images is much larger in resolution than the size of your video export frame, resizing the still image(s) to fit the frame is not at all GPU accelerated, and therefore will use only the CPU.

There is no image larger than the size of the canvas export, nor does it make sense to limit the encoder to CPU if there is a process like that. The GPU should be able to work along side and split the jobs just like every other program/game on the market.

If your asking about the AE bar above that timeline, I'm not talking about that... I'm talking about the final render option through Adobe Media Encoder, which i'm forced to use... because for some bright reason, I cannot export directly to a proper h.264 setting using AE's options... but thats another issue

So the problem has nothing to do with Premiere Pro, because actually you are exporting AE project...

You asked me for this particular project, I answered specific on this. Let me be clear, i have not noticed any GPU enhanced (With task manager on, watching the load of the gpu) performance on any of these programs, AE or AME. It takes me the same amount of time to render the same kind of project on this GPU as it did on my former. (I now run a 3080TI and I had a 2070 Super, both on a 32GB DDR4 3200Mhz, 9900K i9)

Even though "hardware encoding" is ticked on... it doesn't do actually anything. The CPU is proritized in everything. And as I was asked the question earlier, the project does have effects considered as needed to be processed by the GPU, like gaussian blur for example. Funny thing is, in Premier Pro, in the simplest projects ever, like just changing the bitrate of a video (compressing it), it actually uses the GPU, at least that...

Also, this nvidia studio driver is very old compared to the newest game ready driver and for me as a content creator, it is extremely punishing to use something like this. Makes no sense whatsoever

It's not "The CPU is prioritized in everything". Imagine the render/export process as a conveyor belt. It start's from decoding source, then converted into internal format, then filter#1, then #2, #3, etc, then encoding to output format. You can't start next stage (say GPU-accel encoding) until previous is finished. So your process is not "CPU prioritized", it's bottlenecked, by CPU in this case. Since not all algorithms are/can be effectively pararelled, in worse case scenario you will be bonded not by CPU speed in general, but by its single core instead. 
Also, order of effects also may matter as to how fast it renders. Can't tell about AE, but for Premiere Pro it's definetly the case.

As much as I enjoy delving into my imagination to find answers to technical stuff, I still believe even in the case you have described I should have noticed a serious improvement in total time spent to render a project (the same one) while adding a significantly faster and more capable GPU. Some of the processes you described should have been alot faster and the time allocated to the CPU stay the same, which would have amounted to a change of total time to render.

If thats not the case, there is a serious issue in the program which is causing a mismanagement of resources and inefficient use of hardware components. This is an extremely serious issue and it can save millions of creators alot of time and money spent on just waiting for a render instead of actually working.

This is why I have reached out. There must be an error somewhere, a process not working properly that is keeping the renderer from being efficient in resource management.

@bugam33779908 It seems, you missed a point about bottlenecking. Imagine, your CPU renders frame (his part job in pipeline, to be more precise) in 1 sec, and your prev GPU did its part in 0.02sec. Total time=1.02. Will you notice a difference if your current GPU do it in 0.01, and total time become 1.01 ?

 

Also check this video, judging by the user comments, it's still valid despite being 6 years old:

In this guide I show you how to quickly render high quality After Effects projects! Take note! NOTE: Make sure you have QuickTime installed to have the H.264 option available.

Not sure why you insist on being condescending. It is not helpful, nor welcomed.

I already pointed out there are heavy elements to be rendered like gaussian blur that should be handled by the GPU in the project. They clearly are not, and if I remove them, the process becomes much faster. Nor are the others elements being properly tuned in. I am also not running a slow CPU even by today's standards, so even if I do agree sometimes "throwing money at the problem, solves it", this is not one of those cases. It is a clear software related problem, a bug in the renderers resource management that needs to be fixed.

You have a great graphics card for 3D work.  For video editing, it just isn't as important.
