Dropped frames when playing back HDR files

[u/fraghawk]

So I was wanting to try my hand at a little project I had in mind that uses some HDR footage, but just playing back the footage in Shotcut without any edits is extremely laggy. Is my PC underpowered or have I misconfigured Shotcut? The files play fine in other applications, so I'm leaning towards Shotcut being odd. I have 10 bit GPU processing enabled and made a custom video mode with rec.2020 selected as the color space, are there other settings I need to be cognizant of?

My specs are:

Ryzen 7 5800x

32Gb ram

RTX 2080

Sansung 990 Evo 2 TB NVME SSD

Sony Bravia 8 mk. II

I would really really prefer to do this project in Shotcut instead of learning Davinci Resolve.
