After Effects Lagging when moving objects around

Hello!

So, test 01 > launch AE, create a new Composition, and added a single shape layer. Here's a print of the task manager. (sorry that it's all written in portuguese, but I guess it's understandable) A detail to pay attention: I have two GPU's showing up. One of them is from my CPU, and the other, the Nvidia. Here's the screenshot of both of them.

Test 02 > Details screenshot. 
I believe the only thing that's also using alot of the dedicated memory here is the task manager itself. I also made the test without zen running, and it lagged the same. 

Please let me know what this all means, haha. And thank you for your attention, once again. Ill wait for any updates.

Hi @stardustllama 

In Ae 25.0 and later, we use the GPU to accelerate drawing the UI - this provides a signficant performance improvement. However, it does mean we rely on the GPU even more. On a clean Windows 11 machine using Ae 25.5, GPU memory usage was 2.8Gb. If you're using anything else which uses GPU memory (nVidia utilities, etc) you're going to run out of memory on the GPU, which causes performance to take a hit. To check if this is what's happening, first launch After Effects, create a new Composition, and add a single shape layer. Then open the Windows Task Manager. First, on the "Performance" tab, click on GPU 0 (you should only have a single GPU) and take a look at the "Dedicated GPU memory" entry. It should be less than 3Gb - if not, it's an indication that something besides After Effects is using video memory. Second, switch to the "Details" tab. Right-click on the column headers, choose "Select Columns" and make sure the "Dedicated GPU memory" entry is checked. That column selection doesn't make it clear that you can scroll down, btw, but you can. Click OK, then click on the "Dedicated GPU memory" header to sort by that column, and see which process(es) besides After Effects are using GPU memory. If you could report back here with your findings, we would very much appreciate it.

Well, I tried to run AE 25 without anything running on the background, and it lagged still. Tried unnistalling and installing all over again, still nothing. 

Even with programs open, like zen browser, opera gx, discord, spotify, photoshop and illustrator open, the AE 24 runs super smoothly. 

That doesn't make sense! Lol or it does?

We were able to locate a 1060 3GB internally. We did encounter minor laggyness which is inline with the 3GB card but not to the entent demonstrated in the screen grab you shared.

Are there any other processes running in the background when you are using AfterEffects which might impact the performance on your machine?

Oh, okay. If there is any information or anything at all I can do to help you guys solve this, tell me, please. 

Thank you for your support... I'll wait for any updates. 

That does not look good.

One of the major changes we did for 25 was to shift Application drawing from CPU to the GPU. My hunch was the 3G card was unable to bear the load causing things to studder which would explain why AE 24 does not exhibit the studdering

We are trying to get our hands on a similar system so we can get this to happen locally

Hey! 

Just did that test, and it didn't work too. Still laggy. I even recorded the timeline screen in realtime, so you can see what I mean by "laggy". The same thing happens when I try to move around an object or anything, really.

Thank you!

Thank you for the insight.

I have a stong suspicion that it the NVIDIA card that might be causing problems. To confirm can you do the following

1. Plug you monitor to the motherboard - to ensure you use the AMD iGPU for display

2. Open Device Manager -> Display Adapters -> Right click the NVIDIA card and disable it

3. Launch AE 25 and see if the experience improves

Note - To bring the machine back to the original state, re-enable the NVIDIA card in Device manager and switch the display cable back to it

Hey, sure. 

It happens with every project, even with no media at all or media with effects. I can't move objects around properly because it lags a lot, and the timeline laggs too. I've also tried working with the minimum resolution possible, and still lagged. 

What I notice is that the problem is the UI itself, not the program. When I play the media I'm working, it plays smoothly. 

Oh, and another thing, I clean the cache quite often and sometimes (since I can't work a lot with the ui like this) it's like only 90mb. So I don't think could be that, either. 

Thanks!

I tried with CUDA, with OpenCL and the Mercury one, also lagging. 

Can you expand on the exact nature of issues you are facing? 

The symptoms you are encountering may look similar but probably stems from an entirely different root cause.

It will help if you can provide additional details like whether the issue happens with a new project with no media (just a red solid), with a specific effect, with CUDA or OpenCL selected as the renderer etc.

The GPUSniffer log you posted looks fine with all cards on the system being detected properly
