After Effects Lagging when moving objects around

[robw38316308]

I open up After Effects like normal and can animate etc also rendering fine.

Its frustrating when i move shapes around the screen it lags alot.

Is this to do with the AMD 9070 not optimised for it yet?

I change the GPU Sniffer to GPU Sniffer 123 and it works like butter.

Pc specs:

Amd Ryzen 5 7600x

32gb Ram 6000mhz

m.2 7000mbs

Amd 9070

850w power

Is there another solution this weird laggy bug without changing the GPU Sniffer name?

Okay so I recently "upgraded" my gpu from a nvidia 2080ti to an amd 7600xt.  I have been experience intense lag just creating/moving around shapes, using the pen tool, simple things with just one layer in use.  It's a bit ridiculous.  In the last couple of days, I've ran through the internet trying all the basics of fixes from AE preferences to settings.  Nothing worked.  All my drivers and etc are updated.  I have plenty of RAM.  A dedicated drive for my cache(and all purged).  Even uninstalled all my amd driver software programs(Adrenaline n AMD pro software) cuz I saw somewhere that it could be the cause.  But nope....nothing...Not until I came accross a thread on Reddit that said something about renaming a support file in the AdobeAfterEfx called gpusniffer.exe by just adding 123.  And boom no more lag.  This is so great but truly infuriating.  What is actually going on?  What changes by just renaming this exe.  It doesn't make sense to me.  And after a bit of experimenting renaming the file and un-renaming it;  It seems as If my gpu is actually doing it job cuz it shows in the task bar.  

Does anyone know how this works in my situation.

Hi MannieX,

Have you removed the drivers of your previous GPU? I'd suggest removing the residue files manually. If it doesn't help, change the gpusniffer file name back to the original. Once done, open After Effects go to After Effects Preferences > Memory & Performance > GPU Information and share a screenshot.

Looking forward to your response.

Thanks,
Nishu

Hey there,

Yes, I removed my drivers from the previous GPU.  But I will go back in and try and make sure that they're all gone.  I've also remember looking at the GPU info through AE before the GPUsnifferf fix and remembering that it noted the right amount of VRAM but no other GPU info.  Just a bunch of weird numbers.  Will share a screenshot asap

[MannieX]

So with renaming gpusniffer by adding the numbers shows no graphics card.  But my graphics card is still enabled and running when I'm using AE doing the simple things with no lag.  I can also see higher gpu usage when perfoming these simple tasks in AE through the task manager.  The gpu usage was higher than the event of leaving gpusniffer at its default.  I also tried disabling the 7600xt.  It yeilded the no lag result and was no longer visible on the task manager.  Not sure how my computer was still running.  I dunno.

[MannieX]

Not sure if my picture will load but

gpusniffer.exe

Oh yes forget to mention:  Even with everything at default I see device errors for gpu that says "device not started"

Hi @robw38316308,

Thank you for reporting this issue. It sounds like the GPUSniffer is reporting unexpected or incorrect values, which impacts how After Effects can utilize the GPU.

If possible, could you share the output of the GPUSniffer.exe when you run it directly using the Command Prompt?

Follow these steps to see the output of GPUSniffer:

1. Open "C:\Program Files\Adobe\After Effects 2025\Support Files" in Explorer
2. Type "cmd" (without quotes) in the address bar and press Enter to open the Command Prompt to the Support Files folder.
3. Type "GPUSniffer.exe" and press Enter. (If you've renamed GPUSniffer, type the new name).

This should print out detailed GPU specs for your system, which would be hugely helpful in our investigation into why you're currently needing to rename the GPUSniffer to get smooth performance.

Thank you again for reporting this issue and for any further information,

Thanks very much @robw38316308, that is extremely helpful. We now have a ticket open to investigate what might be causing the laggy state in conjunction with GPUSniffer.

Thanks again,

[Puneet98A7]

This is the first time I have seen something like this. I will be happy to take a look at the issue

Please drop me a DM so we can find out what is happening

[Grooooooove]

I'm using 9070tx and having the same issue, solved by renaming it to skip it. 

Which means my AE 2025 cannot recognize the GPU. 

Please fix it asap.......... It's really frustrating. I spent 2 days figuring out what causes the lag.

My solution for now is deleting the AE 2025 and installing AE 2024. The GPU cannot be found without the GPUsniffer anyway. AE 2024 works flawlessly. 

[hackerziin_0342]

Go to Program Files > Adobe > (YOUR Adobe After Effects version) > Support Files. Find the file GPUSniffer.exe and rename it to GPUSniffer123.exe. TRUST ME IT WILL WORK, THAT WAS A LIFESAVER FOR ME!

[Chris5C41]

I've been searching for solutions all day and this is the only thing that's worked, thank you.

[Warren Heaton]

Instead of renaming GPUSniffer.exe, users experiencing UI lag or Preview lag should udpate GPU drivers or try disabling GPU acceleration.

Also, review these two support documents:
• Known Issues in After Effects
• How to manage plug-ins, reset preferences, and launch Safe Mode for Adobe After Effects

For help from the community, go to Preferences > Startup & Repair > and click "please file a bug report".  This copies system info to the clipboard.  Please be sure to paste that into your forum post..

[hackerziin_0342]

i Tried all. my AMD rx5600XT got the latest driver update. but everything is so laggy. i disabled hardware acceleration, is better but is not great, i have a graphic card and i want to use it. how can use the hardware acceleration how can i desbug it?

[Warren Heaton]

@hackerziin_0342 

That has 6GB of VRAM right?  It's a good mid-range option for beginner to moderate work, but your work in After Effects may require something higher end.

You could look into something with at least 8GB of Display RAM.  For solid performance in After Effects, I'd try to get your build to be as close as possible to what Puget Systems is offering for their "Standard" AE workstation or better yet their "High RAM" worksta....

If you're not already doing it, I'd consider rendering Previews at Half, Third, or Quarter Resolution and for longer Comps enable the Skip Frames option.  For example, use a custom Preview that uses Quarter Resolution and skips 1 frame while working on motion and timing, make refinements at Half Resolution, and then finishing touches at Full Resolution.

Hi folks, we think we have a fix for this issue. Grab the latest beta build of After Effect (25.3.0.069) and let us know if you're still seeing the problem.

HI, IT REALLY WORKED, NOW I CAN MASTER AFTER EFFECTS AND MAKE GOOD SMOOOTHY EDITS THANKS! I WOULD GIVE YOU A KISS IF I COULD

[nishu_kush]

A fix for this issue has been rolled out in the latest beta version of After Effects. Can you give that a try? Here's how you can install the beta version: https://adobe.ly/4d7TuBt

Thanks,

[nishu_kush]

A fix for this has been rolled out in the latest beta version of After Effects. Feel free to give it a try and let us know.

[MannieX]

Thanks a much.  I will check it out.

[MannieX]

Awesome, Awesome, Awesome.  Thanks a much.  Everything seems to be smooth with AE Beta.  This is great.  Thanks a much.  Still a bit curious! Do you know what the bug was?

[robw38316308]

I've installed the beta version of After Effects and the fix has worked! Not lagging anymore. I look forward for this fix to be implemented into the main app. Thankyou.

[Puneet98A7]

@MannieX GPUSniffer enables GPU acceleration in After Effects. The bug was in the GPU path when drawing the overlays.

Disabling GPUSniffer (by renaming it) disabled GPU acceleration from the app completely bypassing the bug leading to smoother overlays but terrible overall performance.

[kubajj]

Hi so i saw one post about this issue and its not fixed yet, ae its absolutely unusable for me when the preview is so laggy and no its not my pc, yes i tried safe mode and yes problem still occurs, yes i have latest drivers, no its not occuring on older versions of ae such as ae 2020 - 2024 its only 2025 problem and i feel like its only on amd cards because my friends are using  nvidia card and they dont have that problem. Adobe please fix it
