Quake II RTX Download 1.7.0

id Software’s Quake II launched in 1997, bringing gamers a new single-player campaign, a long-awaited, addictive multiplayer mode that we played for years on pitifully-slow 56K modems, and a jaw-dropping engine that supported 3DFX GPU acceleration out of the box. Colored lighting, dynamic visual effects, and much more, all running at a glorious 640x480, or perhaps 800x600 if you had top-of-the-line hardware.

Fast forward to 2001, when id Software made the Quake II engine open source, enabling anyone to legally release total conversions with complete engine overhauls. Ever since, fans have beavered away on their own personal projects, the latest of which is Q2VKPT.

As Christoph states on his site, Q2VKPT is the basis for future research, and a platform for more ray tracing goodness. So, we reached out shortly after Q2VKPT’s release to ask if our own ray tracing experts, many of whom he worked with previously, could develop enhancements and major additions. He said yes, and this week NVIDIA is presenting the newly-created Quake II RTX together with Christoph at GDC 2019.
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.

“But what’s new with Quake II RTX compared to Q2VKPT?”, you ask. A lot. We’ve introduced real-time, controllable time of day lighting, with accurate sunlight and indirect illumination; refraction on water and glass; emissive, reflective and transparent surfaces; normal and roughness maps for added surface detail; particle and laser effects for weapons; procedural environment maps featuring mountains, sky and clouds, which are updated when the time of day is changed; a flare gun for illuminating dark corners where enemies lurk; an improved denoiser; SLI support (hands-up if you rolled with Voodoo 2 SLI back in the day); Quake 2 XP high-detail weapons, models and textures; optional NVIDIA Flow fire, smoke and particle effects, and much more!
