As you might recall, NVIDIA released the remastered Quake II RTX for free back in June 2019. In-house developer Lightspeed Studios took the work of Christoph Schied with Q2VKPT and brought it to the next level with new path-traced visual effects, improved texturing, and more.

Last Friday, Quake II RTX received a big new patch, version 1.6. The developers added a bunch of new features, though the most interesting ones came directly from the community, as GitHub user @res2k introduced support for AMD's FidelityFX Super Resolution (FSR) and for High Dynamic Range (HDR) displays.
