I mean a way other than normal options that leads to smoother playback ? Is something like that possible ? Yes i use the paid version.
Of course those factors depend on display and its settings, your chosen media player, and your chosen settings for that media player.
So for example there is a panning motion scene in Game of Thrones Season 8 Episode 1, at the start when the kid goes up on the tree and the camera pans from Winterfell to the Army (this is a perfect scene when changing settings to judge smoothness).
I use MPV personally. So I always found a smoothness issue in this scene back in the day. If I have SVP frame rate conversion set to movie x2 and the refresh rate from nVidia control panel to 50Hz. It would play at 48 frames, and those 2 extra frames when they get dropped or delayed, it caused a hiccup in that scene too sometimes. If I set svp motion to screen, it played smooth in most cases at 50Hz, but sometimes when re-checking that scene over and over again it would hiccup sometimes and sometimes it would run smoothly. So I kept digging into mpv's settings and found "video-sync=display-resample", adding that to my mpv configuration, as well as using full-screen-exclusive mode finally adjusted and added an extra layer of smoothness that allowed for 0 hiccups in that scene no matter how many times I replayed it, and since then, everything has been smoother for me. Now every time before I watch content personally I switched my refreshrate to 50Hz and with my mpv settings it's perfect for me.
Here are my mpv configurations if you're interested. These run with my hardware, but doesn't mean they'll run with yours and also pick and choose only the important stuff, you don't need everything for just testing, for example all the lines for the shaders I use at the bottom when you scroll down the code can be removed. The section for changing my subtitles section can also be removed too.
