Premire pro using 100% CPU usage and GPU Cuda is grayed out

try testing only after all those progress bars are completed, and/or turn off the media analysis in the preferances (in your screen shot)....  those background process might be contributing.

Also;  upgrade your video driver, since you opened this post, a new driver I belive was published, and make sure your on 25.3 version of premier pro too....  I noticed you are exporting in 23.97 FPS, and there is a very specific fix in version 25.3 of premier for exporting what it says is 23.98 FPS - not sure if there is a typo, but I would upgrade and restest after you update the studio driver to 576.80 June 17, 2025 version.

Hello, thanks for responding. I have no effects on the videos are this is what my settings look like. I linked a task manager snipped when it was generating the peak file.

As a side note;  Your system memory at 32GB is usable, but honestly a bit too low, really should be 64GB.  whith 6GB reserved for other apps, that doesn't leave you much to work with for Premier, and you probably have chrome running in the background or other apps too.     You can see a spike in the SSD drive usage, I think that memory/disk swap file activity, then it drops down, but even at 9% SSD utilization is kind of high for a SSD, I don't think I have never broken like 3% for a second or two when using premier if/when not reading and writing to the same drive (using M2 drives, I cant tell if you have SATA SSD or M2) but I can see you are using raid drivers for mechanical drives I assume.

to be clear I dont know if the latest updates are usign more memory, and this pushed your config to the edge of the memory you need or not, nor am I saying you need to/must do this to troubleshute, just wanted you to be aware and if you had a easy way to increase the memory, it would at least rule that out  - but I know that may not be possible for everyone.

I don't think you should run out and get more memory right now until we get a better idea, but at some point when it makes sense financially, and its affordable moving to at least 64GB should give you some better performance.

And another note,  do all your windows updates if not already,  there have been lots of under the hood changes and the many small updates have had some positive effects if your at the latest versions.

Your GPU is for sure doing some work based on the task manager you posted; and the 3060 is still supported.  The decode seems to be at near 100% so its doing work;  the 3D resources are running near 100% also; so that GPU is doing some work, and so is your CPU...

Just wondering,  when you imported did you check to see if some of the new features were on, such as the new enhanced visual search and auto transcribe video and if those are running in the background?

You can check to see what background tasks premier is doing in this dialogue:

when you open it it will show a list like this:

Based on that task manager you uploaded, the CPU, and GPU are both doing something, so you will need to figure out what.  Your driver appears to be the studio driver based on what I see on your task manager driver version.

You noted that the machine is taking longer to generate peak files, this could very well be because its doing the background tasks such as preparing the visual search, and you maybe have to wait out the process to be done, or turn them off if your note using them in preferences.

Check this preferences section:

Interested too see what you find after reviewing this.  I am not sure what to look at next if its not the background processing running, that system task amanger shows its doign soemthing and its pretty busy.

ALSO;

Please confirm do you have ANY effects on the media?  some effects can cause it to not be responsive until after you render it/render replace.   It would be ideal to confirm if and what effects you have applied to the media clips also.

No plug-ins being used. Exporting a video at 1mb bitrate and at 29.97 fps. Don't know if this helps but every since I have updated to premire pro 25 I have much longer times to generate peak files in premire. It is using 97% of my GPU to do that. I have a photo of it but can't upload it for some weird reason

I have an NVIDA GeForce GTX 3060. I have 6gb allocated to other apps. I tried using the tool to reintall the drivers and still no luck.

So first, you didnt note what GPU you have,  some GPU's get droped for support,  not sure what GPU you have, but first make sure that the installed version of premier still has support for that GPU (and its the latest STUDIO driver)...  Then....

Please confirm your Nvidia driver version, you should be using the Studio driver (NOT GAME READY), latest version as of 5 min ago is 576.52 from May 19, 2025.

Also; please confirm that your memory settings for Premier leaves some memory for other apps to use; such as:

You can also do a CLEAN install for the driver for nvidia;  this tool should work;

Display Driver Uninstaller (DDU) download version 18.1.1.4

You can re-install the Studio driver after the tool above does its job (reinstalling a driver with nvidia doesnt really clean install it)

Also; it appears that version PP 25.3 was released today for some people, but there is no change log (yet) - if that update is available for you, it may also correct your issue.

If it was me, I would:

-check the memory allocation preference to ensure it has not been modified, move it up MB, and save

-update premier to 25.3 Build 84 if thats available to you now;

-TEST

-use the driver remove tool link above,

-install the STUDIO driver only, not the game ready driver.

-TEST

If its not fixed, repost here, well if fixed also repost 🙂

This should be enough to get you started while others have a chance to look at your post.
