Lag problems with V25.0

[Masshiu]

Hello everybody !

I've just bought an MSI raider 18 hx a14v, which has 64GB of RAM and an RTX 4080.

I'm trying to do some video editing on Adobe Premiere Pro V25.0 but the playback of the video track jerks and lags (even in 1/2, 1/4 and 1/8 resolution) and even after rendering. The blue vertical bar in the timeline that should tell me where I am also freezes at the start of playback instead of scrolling, which makes editing horrible as I synchronize my rushes to the music. These are only 4K rushes.

I did some research and checked the first tips found on the internet, namely:
- make sure to use the Mercury Playback Engine (CUDA) GPU rendering system.
- Allocate sufficient RAM to Premiere Pro (I've tried several values, from 12GB to 50GB, which makes no difference).
- Make sure that no other software uses too much memory or CPU with the task manager. By the way, I've been running the software alone, without anything else, since the computer started up, and it always lags.

I've seen other advice, such as using proxies, but that seems a disproportionate measure to me, given that my old computer, half as powerful (32GB RAM and an RTX2080), did the job without any problem.
Does anyone know what the problem is?

Thank you
