Probably the first time a 20+ year old game won’t run on a potato.
For a while, Nvidia has been adding a fresh lick of ray-tracing paint to the 1997 classic, Quake II. Coincidentally, it’s now done, and being called Quake II RTX. And if you own the original, you can download the entire re-polished version of the game for free. Or the first 3 episodes if you don’t. And if you want the entire game, ponying up the $4.99 to buy the original game gets you the entire ray-traced version for free.
That said, whether or not you’ll actually be able to run it is down to your hardware. While Quake II is over 20 years old, the new ray-tracing is hardware intensive. That new technique is used to render everything on screen. As such, you won’t be able to run the game with less than one of Nvidia’s RTX cards; GeForce RTX 2060 or higher.
Granted, this is far from the height of what ray-tracing can do; Quake II is an old game, so it’s more a working example of potential. That said, for a game its age, they gussied it up real nice.
You can get Quake II RTX on either Steam or Nvidia’s site.
