Sluggish timeline video playback, fast PC

I have an intel i914900k, 96 gb ddr5 ram, samsung ssd 990 hard drives, and asus rtx 5070ti 16gb graphics card. I am using 3840 x 2160 25fps footage with and all-i codec? Shot from a dji mavic 4 pro. The vegas template for the project is 1080p because Vegas would seriously choke on a 3840 x 2190 timeline. The issue now is, vegas still stutterers a lot during playback on the timeline with a DRAFT preview screen. Dynamic RAM previews are really slow as well. It stutters even more when there is a simple cross fade transition. How to fix this performance issue?

Could you share more information about the DJI Mavic footage? MediaInfo would be great; a sample on a file sharing site even better.

I have similar hardware to you and would be happy to try it.

In general you should be able to edit it in best/full at 4K on a system like this. The fade might be an exception with VP 23 as fading events into each other now hurts performance (with a copy of the media performance is better- so fade media a to media b instead of a-a).

If preferences/ file io are not on default settings please return them to defaults with the 5070 doing decoding.
