Last attempt to solve DJI Studio for PC problem

I've posted more about this issue. I have a AMD Ryzen 9 5950X CPU 64Gb and NVidia GeForce RTX3060 12Gb which doesn't meet the system requirements according to DJI Support. The fact is that it sometimes runs smooth in HD in DaVinci Resolve and sometimes it doesn't and stutters. The same in SD (proxy). How is that possible? I mean it runs smooth or it but not randomly or am I wrong.

I've a new Insta360 X5 and still in the box but I like the OSMO more due to it's size and colors.

I know I can use Insta360 Studio but that's adding more workflow and edit 360 footage is already a lot.

Any suggestions?
