![]() ![]() The “PT” in its name stands for Path Tracing, a compute-intensive ray tracing technique that unifies all lighting effects (shadows, reflections, et cetera) into a single ‘pure ray tracing algorithm’. student at the Karlsruhe Institute of Technology in Germany. Released in January, Q2VKPT was created by former NVIDIA intern Christoph Schied, a Ph.D. Ever since, fans have beavered away on their own personal projects, the latest of which is Q2VKPT. Colored lighting, dynamic visual effects, and much more, all running at a glorious 640x480, or perhaps 800圆00 if you had top-of-the-line hardware.įast forward to 2001, when id Software made the Quake II engine open source, enabling anyone to legally release total conversions with complete engine overhauls. 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. In addition, Nvidia announces that it brings raytracing support to Vulkan. All graphic effects are based on raytracing, which gives the 1997 game a completely different look. You will need a GPU that supports the VK_NV_ray_tracing extension – that is, a Nvidia Turing card – to use the real-time ray tracing.Nvidia has been showing a demo of Quake II RTX at GTC 2019, it entails a completely updated version of the game with real-time ray tracing. The Quake II RTX demo is available for Windows 7 and Ubuntu 16.04.6 Linux. ![]() It isn’t the full original game, sadly, but the downloadable demo lets you play through the first three levels with updated graphics. ![]() ![]() Updated 10 June: Quake II RTX is now available for download. You can judge for yourself what difference ray tracing makes in the before-and-after comparisons via the link below – and test it for yourself when Quake II RTX is released later this year. The game runs in a Vulkan renderer using Nvidia’s VK_NV_ray_tracing (VKRay) extension. Quake II RTX also overhauls the game’s models and textures – the update introduces full PBR materials – and adds particle effects for weapons, plus optional fire effects using Nvidia’s Flow middleware. Nvidia has now extended Schied’s work, adding time-of-day lighting, refraction, reflective and transparent surfaces, and improved render denoising. Now also supports time-of-day lighting, PBR materials and particles Q2KVPT can “come close to” 60fps at 1440p resolution when running on GeForce RTX 2080 Ti: the highest-spec current gaming card to feature Nvidia’s RTX ray tracing architecture. The overhaul replaced the original game’s baked lighting with fully dynamic global illumination, ray traced shadows, glossy reflections and one bounce of indirect lighting. One such fan was former Nvidia intern Christoph Schied, who released Q2KVPT, a version of Quake II updated to use real-time path tracing. Id made the Quake II engine open-source in 2001, enabling fans to update the original game for modern graphic technologies over the years. Of all of the real-time ray tracing tech demos being released at GTC 2019 and GDC 2019 this week, one of the strangest involves a 21-year-old game.ĭuring its keynote at its GPU Technology Conference, Nvidia showed off Quake II RTX: a total conversion of id Software’s 1997 shooter, updated to run with pure ray tracing in a Vulkan renderer.
