Trying to grade a clip in premiere pro beta but the lag time between making an adjustment and the program monitor updating is about 3-5 seconds. It used to be basically instantaneous. Enabling and disabling the adjustment layer also takes 5+ seconds for the pogram monitor to display.

Clip has basic lumetri adjustment (exposure / shadow / etc) And above it is a adjustment layer with a lut (slog3 to 709 v2 provided by sony) and a creative effect lut from speed looks. So in node speak, that would be three adjustments or layers. It plays back the clip in real-time but making an adjustment is arduous with or without proxies turned on.

Sometimes after awhile it will become more responsive but it still won't "live update" it will only update once you release the mouse button.

Tried clearing cache and prefs, but problem remains.

Hi @Kirsi21888295ykon and @V-Edit - Can you post your system specs for us. Just to confirm you have good performance in 25.1.0 Release, but in 25.2.0 build 96 and higher you can no longer play your sequence without dropping frames?

Still not fixed in build 96. Any news Adobe or @DaciaSaenz? It has been like this since around build 25.2.5x or something. So a quite a long time and still no fix or at least some news.

But again, Premiere Beta 25.2.0 (Build 96) can't even start playback of one of my current projects (Media analysis is OFF), tried 5 times, with restarts, etc..., so I don't consider it to be a usable version.

The lagging bug with Lumetri Color on Adjustment Layer is not present (for me) in the current Premiere Beta 25.2.0 (Build 96), but is present in the release version, that is 25.1.0 (Build 73)

Some people have posted having issues with Lumetri applied to an AL. I haven't had that, so "I can't replicate it". Which is in itself useful data ... my system, for data comparison, is a Ryzen 3860x CPU, 128GB of RAM, and 2080Ti system.

I don't use that much H.264, but some. Mostly BRAW, ProRes, and some mov. Full 4k through 1080 stuff. All about 24fps/23.976.

Everyone's mileage always varies ...

Ok, and while I am still here: I can add that Global FX mute helps with Multicam playback stuttering. But sometimes some Lumetri effects pop back on without any reason after start-stop, and everything gets laggy again, till I press Global FX - ON, Global FX - OFF one more time.

What I have also noticed, is that CPU going 100% in multicam editing and playback starts to lag if there is an Adjustment Layer on top with Lumetri Color effect. In prior versions everything was normal.

Seems like I am having the same problem! If I place an adjustment layer with Lumetri Color effect, the panel will be very laggy (I have Windows 11, RTX3090, latest driver). It is easyly reproducible even in a simple 4K timeline, with one s-log3 4:2:2 clip from Sony A7 IV. Haven't tested other file formats, but I don't usually work with other formats anyway.
