The bear for older graphics cards is ray tracing technology, so I would say that Cyberpunk probably is the one that uses it most, yes. Control too. Watch Dogs Legion seems to use it quite a bit too.
You can also play some dedicated ray tracing games/demos, like RTX Quake and Minecraft with RTX, which features very heavy ray tracing implementation. First generation ray tracing on the 6xxx cards from AMD is no good, but will no doubt improve considerably next generation. Ray tracing taxes but can be decent/playable on the higher nVidia RTX 20xx cards.
Most games from here on out are expected to implement a lot of it, though. So this fall's games and beyond should have it, optionally. If you turn it off, you won't notice it, but it's yet another bell and whistle, as were the raft of anti-aliasing approaches so many years back. Most gamers, per Steam statistics, still play on nVidia 10xx series cards. There are a lot of 1080s and 1070s out there. So most games still make sure they look good on that hardware.
The key for Cyberpunk is that it doesn't really work that well on older hardware. You want a 30xx series card and if you don't have one, it chugs. That's unusual for developers. They usually want to appeal to the lowest common denominator. This is more like the Wing Commander games, which pushed gaming hardware with each release because they immediately made older hardware obsolete at the bleeding edge. The difference is that not everyone can get that new hardware, due to the shortages, so CD Projekt Red faced a lot of blowback. They also left themselves open to criticism that they didn't fine tune the game well enough to run on older hardware.
