Hi.
Yes it its your Computer. When I google it, did I found out it is a Laptop?
In Resolve the CPU is used to run the app, disk I/O and compression and decompression of codecs.
Resolve does all its image processing in the GPU on the graphics card. More CUDA/OpenCL Cores are better.
4K/UHD have 4 times the pixels of Full HD and require much stronger CPU and a GPU with much more CUDA/OpenCl performance and Video ram.
If you don't have dedicated graphics card will Resolve use the OpenCL in the Intel UHD Graphics 620. I never tried it with 4K, but I expect it is much better with HD.
I suggest that you read the Resolve 15 Configuration Guide:
https://documents.blackmagicdesign.com/ ... _Guide.pdfThe are several thing you can try to makes things better. But I wonder if it ever will be good. I don't know where to start.
But may be you can downgrade to Resolve 12, which has less hardware requirements?
Regards Carsten.
