Quake II RTX was released on Jun 6, 2019 by nVidia. The game was developed by LightSpeed Studios. Quake II RTX is a first person shooter.
This game is available on Steam or you can download it from nVidia. nVidia has been slowly expanding into the game publisher business and LightSpeed Studios is one of the new subsidiaries.
The classic Quake II never looked so good with all new shaders and other improvements. The game is compiled for 64-bit systems so it can use the modern video cards properly. You need the full Quake II game to play the entire campaign, that is available on Steam but there are also a lot of game disks floating around.
Quake II RTX builds on the work of Christoph Schied and the team at the Karlsruhe Institute of Technology, who added ray tracing to Quake II to create Q2VKPT (in turn building upon the Q2PRO code base). nVidia has introduced new path-traced visual effects, has improved texturing, and has made dozens of other changes and improvements, resulting in an experience that rivals games created today, and pushes your RTX hardware to the limit.
You need the RTX 2060, RTX 2070, RTX 2080 or the RTX 2080 Ti to play this version of Quake II. Realistically 16GB or RAM or more is needed due entirely by the video card requirements. The game itself is small so storage costs are negligible.
