Resolve 12.5 has relatively poor decoding performance for H.264, which shows up especially in UHD 60fps files. Transcode the file into a different format, or try using the Resolve 14 beta, which some people have said worked better for their drone footage. Resolve 14 Studio includes GPU accelerated H.264 decoding for new enough NVidia graphics cards, which you have.
