Quake 2 RTX Patch 1.4.0 released, adds support for platform-agnostic Vulkan Ray Tracing

NVIDIA has released a new update for Quake 2 RTX that adds support for platform-agnostic Vulkan Ray Tracing. This basically means that Quake 2 RTX is no longer locked on NVIDIA’s hardware. Instead, this fully path-traced game can now run on all GPUs that support the latest Vulkan Ray Tracing extensions.

According to some early reports, the new Vulkan Ray Tracing extensions also bring some performance improvements to NVIDIA’s GPUs as well.

Quake II RTX was the world’s first game that is fully path-traced. This ray-tracing technique unifies all lighting effects such as shadows, reflections, refractions and more into a single ray-tracing algorithm.

Now as I’ve already said, I still consider Quake 2 RTX as one of the most impressive Ray Tracing games. It truly is a beauty to behold. Not only that, but NVIDIA has created a studio in order to overhaul with RT effects other classic games. Thus, I can’t wait to see what other classic games NVIDIA will overhaul. I’d personally love to see Unreal Classic and Doom 3 with full Ray Tracing effects.

Below you can also find the complete changelog for this latest update.

Quake 2 RTX Patch 1.4.0 Release Notes

New Features:
  • Added support for final Vulkan Ray Tracing API. The game can now run on any GPU supporting `VK_KHR_ray_tracing_pipeline` extension
  • Added temporal upscaling, or TAAU, for improved image quality at lower resolution scales.
Fixed Issues:
Denoiser Improvements:
  • Implemented a new gradient estimation algorithm that makes the image more stable in reflections and refractions.
  • Implemented sampling across checkerboard fields in the temporal filter to reduce blurring.
  • Improved motion vectors for multiple refraction, in particular when thick glass is present.
  • Improved the temporal filter to avoid smearing on surfaces that appear at small glancing angles, e.g. on the floor when going up the stairs.
  • Also improved the temporal filter to make lighting more stable on high-detail surfaces.
Misc Improvements:
  • Added git branch name to the game version info.
  • Improved the console log to get more information in case of game crashes.
  • Increased precision of printed FPS when running timedemos.
  • Reduced the amount of stutter that happened when the game loads new geometry, like on weapon pickup.
  • Replaced the Vulkan headers stored in the repository with a submodule pointing to https://github.com/KhronosGroup/Vulkan-Headers
  • Static resolution scale can now be set to as low as 25%.
  • Vulkan validation layer can now be enabled through the `vk_validation` cvar.
  • Updated SDL2 version to changeset 13784.
