No, no, I didn't set anything special in DaVinci. I just tried the difference between manual and automatic selection of Graphic card, but the result seems to be the same = no success = very poor encoding performance to H.265 ... see image below

Unfortunately there is no possibility to encode via UHD630 (even that iGPU is listed), because it is not selectable and is grayed-out as you can see. This would be a sufficient workaround for me, because encoding via iGPU was quite fast.

BTW it is a free version of Davinci.

Thanks for any help.
Here, uncheck Auto and test Metal and OpenCL. Metal should export fast.

In Resolve, H.265 export is carried out on the GPU. It may simply be that Intel's 10700K H.265's encoder is better than RX 6600XT.
When export to H.265 start in Resolve (free version) processor goes to load and all fans start spinning. So I suspect that dGPU is not being used.

Probably, the main root cause. What's the CPU load when exporting?

Could be mostly related to the free version. Try to export using Resolve Studio.
