Rendering is extremely slow since the 2025 update

[svens82]

I don't know why, but since the update to 2025 (v25.0.0), Premiere Pro renders very, very... very slowly.

Not every clip, but when I use certain effects (like Neat Video Denoiser) and the line is red, it takes hours to render a 1.5-minute clip.

When I pre-render (by pressing ENTER), it works fine (a few minutes) and the line turns green. However, when I try to fully render the clip, it still takes over an hour. By the way, my Task Manager says only 11% of my CPU is in use.

I also tried the Beta version of Premiere Pro – same problem. I guess it’s a software setting (since the update to 2025).

In Premiere Pro, my render settings are "Mercury Playback Engine GPU Acceleration (CUDA)."

RAM available for Premiere Pro: 52 GB
For export, I use H.264 with an HD file size of 328 MB.

I also deleted my media cache.

I'm using Windows 11 64-bit.

About my hardware:

• AMD Ryzen 9 5900X 12-Core
• 64 GB RAM
• NVIDIA GeForce RTX 3060

Any ideas?

Jumped in this forum hoping to find a solution. but i guess adobe really doesnt care. I'm having the same problem. I have 21 second 4k sequence that is taking hoursssss to render. Mind you i do have a good amount of adjustment layers on there. I don't know if its more time consuming to downgrade or change the project.

i guess its time to learn Davinci. I had avoided it it for so long because its so confusing.

It does seem that the cause has something to do with adjustment layers. Better in 25.3. One simple adjust Layer with maybe a blur seems ok but stack on a color adjustment layer and it really bogs down.

That... slowdown in performance is annoying. I use the same workflow since over 2 years. In this time period I've upgraded my graphic card from quadro k4200 to p4000 mostly due to some version update and lack of GPU support on k4200 which was very good graphic card. Anyway, after change my graphic to P4000 everything was fine until some latest updates. Now I do not know to do next. Maybe downgrade to some stable, and reliable version? But which one? I suppose I have to clean Adobe remains from drive completely after deinstallation and then install that specific version. Which one work flawlessly with CUDA? And don't tell me that I should upgrade my graphic card to something newer... Please. This is not the way.

hey i found the solution. uninstall premiere. find the  download for the premiere pro very first 2025 model or roll back to 2024. boom problem solved. make sure you clear the cache of your current version before uninstalling, and save any projects done in your current running model on the desktop.
