The lowest-end RTX cards that Nvidia recommends for real-time ray-tracing current start at a $339 MSRP. Running on a Vulkan renderer, with support for Linux, Quake II RTX is a pure ray-traced game. That means all lighting, reflections, shadows and VFX are ray-traced, with no traditional effects or techniques utilized. Running on a Vulkan renderer, with support for Linux, Quake II RTX is a pure ray-traced game. Global lighting effects, including realistic reflections, refraction, shadows, ambient occlusion and global illumination are a result of the path-traced simulation of light. He said yes, and this week NVIDIA is presenting the newly-created Quake II RTX together with Christoph at GDC 2019. Such lighting detail doesn't come cheap for the moment, though. Quake II RTX is a cutting-edge, ray-traced reimagining of id software's old school classic, by NVIDIA's Lightspeed Studios.
You can see the difference in the trailers embedded in this post or by using this Nvidia-provided comparison tool. As part of the Quake II re-release, the minimum and recommended specs for the game have changed (quite significantly) since the game first hit the scene in 1997. Unlike the pre-baked lighting systems used in the past, ray-tracing simulates the actual path of multiple rays of light off different surfaces to create more accurate color and brightness data for each object.
