That's pretty old 3D rendering tricks causing those overall though. Like I fail to see recent games doing those at all.

Overall, shadows aren't the hard part nowadays, it's light that is. Global illumination and light bouncing back around that is. Though shadows ARE very expensive still.

It's getting better, but correct shadows cast on dynamic objects are still a relatively recent thing. Can't test now, but i would bet some modern titles still only do shadows on static geometry on lower settings.

John Carmack made it a point to show Doom 3 doing exactly that, in 2004, 19 years ago.
