I don't understand PERFOMANCE in 2 MONITORS, it doesn't make sense...

[Sherex]

MY PC: i7 12700, 3080 Ti, 32 GB RAM HyperX CL14, 3x M.2 Gen 5.
(Yeah, I’ve got a pretty solid rig.)

Hey guys, I usually edit with two monitors, and performance is great — well, almost great. It could always be better. Nesting clips, for example, isn’t as fast as I’d like.

So here's the thing: I decided to try editing with just one screen... and Premiere runs incredibly smooth. Nesting, playback — everything feels buttery.
But... why? It doesn’t make any sense. I’ve looked all over YouTube and can’t find a clear answer. I'm not using Mercury Playback Engine, and I’ve already optimized quite a few settings in Premiere.

I’d really like to hear your thoughts on this. I want to go back to editing with two monitors, but after seeing this massive performance difference, I’m just like...
C'mon! Seriously!?

That's bizarre to me, as I work with four screens, one of them the transmit out one, and have no troubles, lag, anything. About a 5 year old rig too ... 24 core Ryzen 3960x, 128 GB of RAM, 2080Ti, and working off internal SSD drives. Using mostly 4k BRAW, some ProRes, All-I mov and some mp4, the odd Sony or Panny or Nikon file.

And I do a fair amount of nesting, which doesn't seem to make any difference in playback on my machine. And a fair amount of complex multi-layer Lumetri color stuff, audio mixing too.

So ... what is the media you're using, and the effects? Trying to figure out what might be the trigger here.

Empty space, with a new project. If I use 2 monitors, is not as fast as using 1, that's a fact.

There is many many many post, people complaining the playhead is lagging as hell and they can just fix that undocking the timeline.

I don't know, I wish some people can help

Hi!

I'm sorry to hear about the performance issues you've mentioned. Please share your current Premiere Pro and NVIDIA GPU driver versions.

I recommend trying a new Workspace layout to check if this issue is workspace-specific. If you go to C:\Users\username\Documents\Adobe\Premiere Pro\25.0\Profile-username\Layouts and move the contents of that folder to another location, Premiere Pro will create new workspace files on the next launch. Create a new project and let us know if you still see performance issues.

Thanks,

Ishan

If I close tabs it gets better, this is a know issue, if I open a new workspace and I set up same as I have, the problem still remaining

I don't know if that's a issue of using different refresh rates or what... What I know is with one monitor premiere fly!!!

Are you creating separate panel-group 'windows' on the two monitors, or dragging the Premiere panel across two monitors?

As the first works, the second one, Premiere gets cranky.

I'm not on Windows but any chance your PP interface straddles across both displays?

[Sherex]

PP you mean the interface?

Nop... it doesn't go across, but I have windows on the other one

Does any Premiere panel or panel group on the 2nd monitor extend to the edge of that screen?

Make sure no panel on that monitor *touches* the edge of visible screen.
