The other thing that caused me to ditch the GoPro was that it took hours to download the video to my computer, using whatever software GoPro provided for that. And then doing anything to the video seemed to take forever. Maybe I just didn't have enough computing power in my old Dell laptop?
I don't use the GoPro software. I take out the micro SD card, put it into a micro SD to SD adapter and put that into my laptop. Then I open the files in File Explorer like I would any other file.
Not sure what your specs on the Dell Laptop are but I use an older Dell XPS 15 and while it does struggle a bit with 4k, I can edit in 1080 and then render in 4k after the editing process. Plus with Resolve, I can generate proxy media which allows the media to playback at a rate you determine (half or quarter resolution) for faster editing.
The GoPro app has been terrible from the get-go
