You don't need VRR for this, but there are some step functions of usefulness:

24Hz - now you can correctly play movies.

30Hz - NTSC (deinterlaced) including TV shows + video game emulators.

50Hz - (24 * 2 = 50 in Hollywood. Go look it up!) Now you can correctly play PAL and movies.

120Hz - Can play frame-accurate movies and NTSC (interlaced or not). Screw Europe because the judder is basically unnoticeable at 120Hz.

144Hz - Can play movies + pwn n00bs or something.

150Hz - Unobtanium but would play NTSC (deinterlaced), PAL and movies with frame level accuracy.

240Hz - Not sure why this is a thing, TBH. (300 would make sense...)
