25.1 update make after effect view port very slow

A Good News For Y'all. They Have Managed To Fixed That Issue Of Timeline Lag in Their Latest 25.3.0(Build 64) Beta Version. I'm currently Using It & There's No issue Except Some Bugs. Which I think Will be fixed When The Stable Version Will release.

Wellcome Buddy.Glad To Help You❤️

Hmm, mine doesn't work that way for some reason. I've checked keyboard shortcuts and found out that it was Ctrl + F12. Done it and it worked! Thanks for your time.  

Brother Its In after Effects When You open after effects ,After That Press f12 and Do So

Does anyone know how I can do this in Win11? 

Does anyone know how and where in the OS I can do this? 

Wellcome Brother ❤️Now your after effects will be working fine

@natasha_2990,

Thank you for your quick response. It helped me.

But if anyone needs it, the DS.GPUSnifferLaunchTimeout setting can be found in the Debug Database View, when you click on the "Console" word with RMB.

(AE 2025 v25.2.2 ).

Press f12. & A console option will appear.

Right cluck and Go to option Abvoe trace volume.

Search GPu And All Gpu Options Will appear. Change The Sniffer Gpu value to 0 And Press Enter. 

Restart After Effects It'll work normally. Only You Won't able to use Advance 3d.

Hello, i have the same GPU and the same problem. Сould you describe how you changed the DS.GPUSnifferLaunchTimeout setting?
