UR22C - installation

Hi everyone, I found an excellent offer from Helix Native+Cubase Artist and this audio interface (UR22C).
initially I thought of using the software only with my previous audio interface (one from ik multimedi) but for reasons mysterious to me the sound in Cubase with the native plugin is painful, it seems like digital from the 2000s, muffled… I don’t know what am I doing wrong, in amplitube everything comes out perfect and crystal clear with the same sound card…
in any case, since the package included the new ur22c, I want to give it a try.
I don’t want to burden my PC with useless software, to be able to use it in Cubase is it enough to download its drivers and that’s it?
I ask because the manual indicates to also download Steinberg Ur-C Extension and Basic FX Suite.
A thousand thanks
