(solved) I can't get my linux system to run properly

I chose to use opensuse tw kde based on some vm tests. The installation was easy but for some reason the video playback on youtube is terrible. It stutters. First thing I did after install was to use opi to install codecs. Then I used Yast to get the Nvidia repo. Lastly, I used the software manager to install the video g06 driver.

To be honest I am happy using Windows 10 but I wanted to try Linux again because of the privacy and security, but there always seems to be something whenever I try to use linux. Should I keep using Windows or try a different distro?

My specs:

1080ti, ryzen 2600, msi b450 tomahawk.

Update: It was the secure boot setting. Nvidia drivers don't work with it on I guess. Thanks for all the other information though, more to look into.
