How can I fix performance issues in Adobe Premiere Pro when working with 4K footage?

[Alex_5553]

I'm experiencing lag and slow rendering times while editing 4K videos in Adobe Premiere Pro, even with optimized media. I'm using a high-performance PC, but the playback still stutters, and export times are longer than expected. Are there specific settings or workflows I can adjust to improve performance?

We need details or it's just guessing.

OS/RAM/GPU/vRAM, GPU driver, types of drives in use abd whether internal or external. With connection if external.

And media details  ... format/codec, framerate and framesize, 8/10/12 bit, created by what device?

How many tracks video, how many audio, and what effects in use?

Exports done on the same drive as media and/or projects, or to a different drive?
