I don't ONLY take advantage of the source engine's physics in HL2, I also use bhopping to my advantage in counter strike mods like this one.
If you wanna play this server: steam://connect/103.212.224.2:27015

This mod in particular is called jailbreak and it's where I learned all the crazy stuff like bhopping. This is in CS source, but Jailbreak is on pretty much every other moddable source game too. I think it started as a quake 2 mod.

I don't like to admit this, but I've spent like over 1500 hours in jailbreak

edit: The current server is called Oceanic Servers Jailbreak. This came from Domination Servers, being briefly named Backlash Gaming, and before that Momentum Networks, and before that it was Freedom Gamers. That's the one you see in my original CS:S jailbreak video: https://youtu.be/56RQp8lq_sU

Before that it was Xtreme Jailbreak (XJB) https://www.youtube.com/watch?v=OT2Y4_J1ee0
and before that Missing in Action (MIA)
